in botany: A genus of the monogynia order, belonging to the tetrandria class of plants; and in the natural method ranking with those that are doubtful. The calyx is monophyllous and quinquifid; the corolla monopetalous, and its tube is short; the filaments are four in number, and hooded at the place of their insertion; the style long and thick; the stigma bilamellated; the capsule is round, bivalved, and contains a number of small seeds.—There are two species, viz. the ficata and ramosa; both natives of Guiana. Both species are bitter, and employed in dyspepsy, and to promote the menses; they are also recommended in visceral obstructions.
