founded the Adam's apple with the potnpolmoes or pampelmous, and have joined the two under ihe name of Cilrus decumanum.

Sloane, in his work on Jamaica, gives us a figure and description which is entirely suited to the genuine Adam's apple, afterwards adding that there exists a variety having the color and flesh of the orange. He characterizes in like manner and connects the two species in his Latin Synonyms. I have preserved m this article only what belongs to the Adam's apple, leaving for the article upon the Pampelmous, that which is peculiarto it. Rumphius.like Sloane, confounds them in his herbarium amboinense, and these writers have been imitated by Linnaeus and the botanists who have followed him.

Adam's apple is one of the hybrids earliest known. We find a description of it in the History of Jerusalem, by Jaques de Vitry, and in the greater part of the works by Arabian authors, who knew it under the names of laytamou or zambau.

Marco Polo found it in Persia in 1270. It was known as Adamo by the ancient Italian writers upon agriculture, such as Gallo and others, and by the Spaniard, Herrera, under the names of toronjo or samboas. Mathioli calls it lomia; Ferraris calls it Iumia vaUntina, a name also given it by Volcamerius.

This fruit is known in Liguria under the different names vipoma iVAdamo, of pompoleon, and of decumano. At Versailles it is called ,pompokmi: also by the gardeners of Paris.

Adam's apple is reported under the name of Citrus aurantium maximum, in the Table of the Botanical School, belonging to the Museum of Natural History at Paris, where arc cultivated several fine and vigorous trees.

It appears to be a lumie, or a hybrid of orange and citron. (I have placed this among the lumics, because it shows traits of them; but I own that I have never tested it by the seed-bed, as I have done with all other races which give seed. I propose to try it at once, and shall not be surprised if the result shows, in this plant, a fifth species of agrume. I have already many reasons for supposing so.) The tree resembles the Chinese citron. Its branches short, often flattened, bear large leaves, which are sometimes lanceolated, sometimes notehed at their edges (crenated), sometimes quilled. They are of a very deep green, and have two very prominent wings to the petiole. The flower, arranged in large clusters, is very large and fleshy, like that of the citron, and entirely white like that of the orange, having thirty or forty stamens. The fruit is round, and four times larger than Ihe common orange. Its rind, smooth as an orange, is green at the commencement, and at maturity is a pale yellow. It is thin, and marked in places by slight clefts, as if it had been bitten. To this peculiarity it owes its name of Adam's apple. Under this skin, which is insupportably bitter, one finds a second, like the citrons, thick, white, leathery, and bitter. This encloses a pulp divided into eleven very small sections, which contain an insipid, slightly acidulated juice. The seeds arc covered by a reddish pellicle, aud arc formed by two whitish cotyledons.

This variety is cultivated in Liguria only by amateurs and seedsmen, and is multiplied by

grafting upou the bigarude. At Salo it is grown from seed, but is used only as a subject upou which to graft the orange.

There ate many plants of it at Versailles, at the Jardin des Planles, and in the gardens of Paris.

The fruit is good for nothing, and is sought for its beanty only, as it is neither edible when raw, nor agreeablefor confits.

i The violet-fruited Bigarade is a singular va riety, and very little propagated. It is not spoken of by Ferraris or Volcamerius, neither is it in the works of botanists who immediately followed or preceded them. We find it described only by a tew modern writers.

1 have seen the fruit only in a painting owned by M. Michel, (editor of* the "Treatise upon Trees,") who obtained it from the heirs of the celebrated Duhamel; and the plant in the orangery of the Museum of Natural History, Paris.

This, which is a tine plant, has the appearance of the ordinary bigarade, having the same leaf. One would not notice anything remarkable, unless that the top is a little more bushy.

I should have classed it among tho varieties of the bigarade, had not the spring growth revealed to me a phenomenon, which convinced me that it was but a hybrid.

Its shoots are of two kinds; the one arc whitish as those of the orange, the others arc of a very deep violet color, as those of tho lemon. This violet color characterizes also a part of its Mowers, which grow upon the same branches with those entirely white. Its fruit is likewise shaded with violet in the same way in which the red orange is shaded with blood color. I do not know the nature of its pulp. I am told that it is yellow and sharp, as in the bigarade.

It is easy to conceive that this variety owes its origin to tho influence of tho pollen of the lemon tree upon the seed from which it has come.

It is one of the most singular results of impregnation.

It is desirable that this hybrid be multiplied, on account of the beauty of both fruit aud flower.

The starred orange is a fruit whose rind presents ribs a little ra<sed, running from the peduncle or stem, and ending in a small mamelon or nipple, which crowns them.

These fruits arc known in Liguria by the name of melaroM, because of an odor of rose which some pretend to find in them. This plant is small, and the branches thin and pliable; the leaf is oblong and lanceolate, with winged petiole; the fruit is small and flattened. lis rind,divided into many raised nbs, Las lhe color of a lemon, and a sweet odor slightly resembling that of the bergamot. The pulp is white, and juice acid, enclosing many seeds. This variety seems to belong to the class of hybrids. It takes after the orange in leaf and form of fruit, and after the lemon in color and acidity of juice. Its odor, very sweet, is apparently the result of the combination of the odorous principles of these two species.

Bizana: Ccdratl della bizaiia. (Vole., t. 2, p. 171.)

The mixed-fruit bigarade, or the bizarrerie, is, perhaps, the most pronounced, and the most singular of hybrids.

It was discovered at Florence in 1614 by a gardener who had obtained the plant from seed, and not dreaming of the phenomenon which lay hidden in it, he had condemned it, according to usage, to be grafted. Happily, after some years, the graft perished, and the forgotten tree, already adult, sent forth wild branches which produced these marvellous fruits. The gardener, surprised, multiplied the new variety by the graft, and made it quite profitable to himself. He making a mystery of its origin, everybody thought that the wonder was owing to the industry of the gardener, who had mingled by the graft the buds of these three species. Bftt the singularity of the phenomenon attracted the attention of philosophers, and a physician succeeded iu obtaining from the gardener the avowal of the true origin of this tree.

To Pierre Nato, a doctor of Florence, we are indebted for this anecdote. He published at this time a very learned dissertation upon this hybrid, of which he gave the history and a very minute description. I have many times compared it with the specimen of the tree which I own, and also with those at Genoa, in the garden of M. Durazzo, and have found that they corresponded in every particular with the description.

The bizarrerie is a bigarade, bearing at one and the same time bigarades, lemons, citrons of Florence, and mixed fruits.

The tree looks like a bigarade. Its leaves are shaped sometimes like those of the orange, and often like those of the citron, sometimes uniting ihe two. There are striped, there are long, there are quilled ones. Most of them have the winged petiole, like the orange leaf. The flowers bloom in spring and in autumn, having, like the leaves, divers forms. Some have petals, white inside, while the outside is shaded with red, aud set themselves as citrous. Others, nearly white, 1 with corolla much larger and more pronounced, produce mixed fruit, while still others have a perfectly white corolla, producing nothing but 1 bigarades. Some have no pistil, and drop oil'.

The fruit follows the caprice of the rest of the tree. One sees sometimes a bigarade in form of a lemon; others arc mingled lemon and orange, at times round, sometimes having a nip- 1 pic at the summit. Others have skin of an orange and pulp of a citron. These trees bear also citrons of many forma, of which snmr uuitr the cit

ron and the orange, and, finally, there arc fruits of which the outside and inside show four parts crossed, of which two are citron and two arc orange, while by the side of these are oranges perfectly formed, without the least mixture. It is necessary to say that the orange is always a sour fruit, and that the citron is the citron of Florence.

The bizarrerie was at first multiplied by means of the graft. It has been remarked that the buds, of which it was difficult to distinguish the nature, developed often only simple oranges er citrons.

There is another caprice of this tree still more singular—that of a citron coming from a bud which grew at the .axil of an orange leaf, and conversely the orange from a bud of which the leaf is citron. This phenomenon deceived so often the gardeners, who obtained from their graft a simple orange or citron, that recourse was had to layers, and only thus can this beautiful tree, with all its caprices, be multipled.

It is cultivated only among amateurs, aud is common in Tuscany; but I have seen it in Genoa only in the garden of M. Durazzo.

The orange of sweet fruit presents a large number of well-marked varieties, and but few subvarieties. Among the varieties are two which bear the characteristics of the type. First is the common sweet orange, or Portugal; second is the China orange.

It is useless to eudeavor to ascertain whether Nature created originally the first, of which the fruit has a little thicker skiu, or whether it is a variety of the second; therefore, we will take one for type, and this will be the aurantium vulgare; aud we will place the aurantium tinense at the head of varieties, of which there are eight.

First. The type, or Portugal orange.

Second. The Chiua orange.

Third. The red-fruited orauge.

Fourth. The dwarf, sweet-fruited orange.

Fifth. The olive-shaped orange.

Sixth. The double-flowered orange.

Seveuth. The sweet orange, with edible skiu.

Eighth. The pompclmous.

The hybrids arc very numerous. We have put two among the bigarades, as that species dominates in their characters. Two others have been ranked among citrons, and three among lemons.

We shall give to the list of oranges but three hybrids, in which the traits of the orange are conspicuous:

First. Is the sour lime, with orange flowers.

Second. The varieguted lime, or orange with white fruit.

Third. The striped lime, or Turkish orange, w ith variegated leaves.

I have seen many sub-varieties which arc connected to these hybrids, but 1 consider it useless to describe all these sub-divisions, whoso additional characteristics furnish nothing new.

Any person adopting the principles of uiy theory could class thenr for himself on occasion, and connect them to tho variety to which they belong.

Neither have I thought it my duty to place in this arrangement a great number of other singular races, of which one rinds the names in modern works, without their characteristics beiug there dotei mined. They do not exist in the gardens of Italy and Provence, nor in those of Spain, where I have sought for them in vain. I have come to believe them but imaginary varieties, or else species of India, not known in Europe. Some botanists have also founded species upon the presence or abseuce of the thorn (Citrus inermit).

I have already remarked that this part, so natural to the orange, is sometimes lacking in individuals produced by an extraordinary fecundation.

This phenomenon, analogous to that of the scarcity of hair, which distinguishes sterile beings in the animal kingdom, forms one of tho traits accompanying often the choicest varieties; but it does not of itself constitute a variety.

It is because of these reflections that the thornless orange has not been placed in this table.

Citrus aurantium OlyglponouM.-: Oranger dc Portugal.

The orange of Portugal, or common sweet orange, is a tree growing to a great height when raised from seed. 'Its leaf is green, having a winged petiole, its shoots are whitish, its flowers entirely white and very odorous, though not equal m perfume to those of the bigarade.

Its fruit, ordinarily round, is sometimes flattened, sometimes a little oblong. The rind, less than an eighth of an inch in thickness, is of a reddish yellow, and full of aroma; the inner skin is a sallow while, spongy and light. The sections, nine to eleven in number, contain a sweet juice, very refreshing and agreeable; its seeds are white and oblong, germinating very easily and reproducing usually the species with little change. There is a variety with no thorns; it is the race cultivated mostly by grafting, and is seen in all countries where this method of propagation is followed. In places where the orange is grown from seed, it is rare to find it deprived of thorns.

The China orange is a variety excelling all others in the perfection of its fruit, of which the juice is the sweetest, tho most abundant, and the most perfumed. The skin is always smooth, glossy, and so thin that one can scarce detach it from the pulp. This is characteristic of this variety.

The orange of China grows from seed, as does that of Portugal, and I have in my garden many individuals of it which havegrownfromseeds of ordinary orange. It has, commonly, a thorn by the side of the bud, but there are those from seed which lack this part.

Rumphius reports under the name of aurantium sinense, or, lemon tnani»t<jiiw', a species of sweet orange, tit Amboyua, which seems to be the same as this. He says that that_ tree grows higher and more rounded at top than the sour orange, a difference which also distinguishes them among us; that its leaf, furnished with a thorn, is long and winged; that its fruit, round and large, is of a blackish-green color, and its juice is sweet and vinous.

He adds that there is a second variety with fruit smaller and less sweet, and a third, of which the tree grows extremely high, and has flowers and fruit larger than ordmary oranges.

An examination of their nature would be necessary in order to decide whether they belong to our European varieties.

Orange rouge de Portugal: Orange grenade.
Orange de Make. (Nouv. Diet. d'Hiot. Nat.)

The red-fruited orange is a singular variety. Its appearance, its leaf, its flowcr, are all exactly like the common orange. Its fruit alone is distinguished by a color of blood, which develops itself gradually, and like flakes. When the fruit begins to ripen it is like other oranges; little by little spots of blood-color appear in its pulp; as it advances to maturity these enlarge, becoming deeper, and finally embrace all the pulp and spread to the skin, which is, however, but rarely covered by the peculiar color; yet this sometimes occurs, if oranges are left upon the trees after the month of May.

This orange is multiplied only by grafts, having few seeds, and those of little value. This is a proof that it is a monster; if it were the type of a species it would yield more seed and reproduce itself by seed. Its branches are without thorns, its fruit is sweet, but less so than the China oranges, and it has thicker skin.

It is cultivated largely in Malta and in Provence. In Lignria it is found chiefly among amateurs and seedsmen.

I would here remark that the greater number of botanists, in describing the India oranges, speak often of varieties which are distinguished by a vinous pulp: Medulla vintsu, (Rumph.) Cum yauru rinositate,{lb.)Maiulfa vinosi'.luporin, (Kirmph.) It appears very probable that they have intended to express by the word cinosa (wine-like) the blood-color which distinguishes our red orange. If this bo so, our orange is of Indian origin evidently, and may well be a hybrid of the Citrus a urantium vulgare, and somc one of the species of India.

It is unknown in Liguria and Provence.

tain sweetness when the fruit remains on the trees until August. The orange of edible skin does not merit cultivation, except for completing collections.

The Citrus ditHn,aiui lius been often confounded with the /,omum Adami, both varieties being of an extraordinary size, consequently the name decumana or dccumanus, which signifies ten times greater (derived from decern), has been applied indiscriminately to both. They present, however, traits so different that it is necessary to put the first among varieties, the second among hybrids.

The aurantium decumanum is the same as the limo decumanus of Rumphius, and the malus anrantia fructu omnium uuuimo el suarissimo of Sloane, and is a veritable orange tree, beariug extraordinarily large fruit, yet having all the characteristics of the orange.

In India this variety gives a numerous gradation of sub-varieties, described principally by Rumphius in his herbarium amboinense, and of which some arc perhaps hybrids crossed with bigarades, citrons, and lemons.

This writer describes some having red and sweet fruit; others with fruit sour and skin edible; still others with insipid fruit and bitter skin.

Sloane confounds also this orange with the Adam's apple, and after having reported it as the malus aurantia fructu rotundo maxima Jmileseente humanum caput execdente of many botanists, he calls it the malus aurantia utriusr/vc India; fructu omnium mtu-imo et suavissimo of Pluken, which is the true pompelmous.

Linnieus, who wrote after these, united them uuder the same name, and appeared to indicate the Adam's apple in the mains aurantia fructu * r * * r ma-Hmo of Sloane, and the pompelmous in that of Meist.

All this clearly proves the existence of a sweet orange, extraordinarily large, whose hybrids and varieties arc so numerous that they cause confusion in names.

This orange is not connected with the aurantium -maximum of Ferraris, which appears to bo a hybrid of two oranges, and which has trails peculiarly its own.

I do not know whether this t rce is cultivated in Europe. I have many times visited gardous in Italy and Spain, where they pretended to have it, | but have always found it was but the Adam's I apple. I have, however, seen one of its fruits brought from America, and preserved in spirits of wine, at I he Museum of the Botanical Garden, Paris. Its size is truly extraordinary. I have never seen an Adam's apple approach log it in volume. Its oulcr skin is smooth, miil of Hie color of the orange, which il exactly resembles in form.

I do not know Ihe nature of its inner skin and pulp, but the descriptions of Rumphius and others teach us that there exist several varieties, some having sour and some sweet fruit. 1 have a fancy that the fruit at the Museum belongs to these last; for the sour fruit is said to be a pale yellow, the color of the Pomme d'Adam—very far removed from the beautiful, golden fruit at the Museum.

Millar says that this orange was carried from India by a Captain Shaddock.

There is a certainty respecting Ihe origin of the Adam's apple, though the history of the pampelmons is obscure. We know that the first, resembling the pampelmous in size, and attached to it by many varieties, has been cultivated in Europe for more than 500 years. It is possible that the English isles received it from Asia, but it is certain that the Spaniards, who acclimated it upon the continent, brought it from Spain, where it was cultivated from the time of the Arabs.

Its pulp is sweetish and has little perfume.

It is cultivated in Liguria by amateurs and seedsmen.

Art. V.—Of Monstrous Fruits.

No genus of plants is so much disposed to yield monsters as the Citrus. These are of two kinds, monstrous races and monstrous fruits.

We have seen that monstrous races are due only to an extraordinary fertilization modifying within the ovary the germs that give them birth.

We have observed that the monstrous fruits appeared also to be produced by the action of a forced fertilization, which caused a modification in the forms of the ovary.

The first fact appears carried to the last point of evidence. It establishes the influence of the pollen upon the organization of germs, without, however, destroying the pre-cxistence of these embryos in the ovary.

The second fact is not so well established, but the consequences of it are much more important. So that whoever succeeds in confirming it by exact and repeated experiments will have fixed a principle of vegetable physiology now uncertain; and which has been judged until the present time, by a system of analogy, with the animal kingdom, fie will have determined the measure of co-operation which the male principle has in reproduction.

The fact of monstrous races can be reconciled with the prc-existence of the germ in the ovary; for this germ, receiving life but by the agency of the fertilizing part, may, by this operation, be altered in the principles of its organization, and give but vegetable mules.

But the fact of monstrous fruits would appear to destroy the theory of this pre-cxistence. Hero the pollen changes the form and nature of the ovary, and multiplies the embryos in this envelope in a singular manner, such as the anrantium ftdiferum, the ewniculatum, the digitatum, and the orange that I have obtained with a lemon border.

The anrantium faUferum presents a super-foatation, an imperfect development of many germs enclosed one within another, or united under the envelope of an exterior germ. These germs—did they exist in this ovary, or have they been formed there by the pollen which has fertilized it? This is the problem which remains to be solved.

On the one hand I observe that these monstrous developments have place, very often, in flowers of which the fertilization has been forced by a superabundance and mixture of pollen. On the other I sec that this phenomenon is very frequent in the monstrous races, such as plants with double flowers, and appears to show modifications in the germ analogous to those which produce the change of sexual parti into petals. ; These two observations may be the base of
