The seed being attached to the upper part of the carp. makes it pendulous with the radicle pointing upwards; this difference from the true Ranunculi is only apparent, and is caused by the singular point of attachment of the seed, the radicle being in fact inferior.-In damp places in fields.

B. heterophyllus (Fries); floating 1. with dentate or cut lobes, fl. from the axils of the submersed or floating leaves; or B. peltatus (Fries); floating 1. subpeltate with a cordate or truncate base and crenate lobes, fl. from the axils of the floating 1. alone.
