CLUTIA, in botany, a name given by Boerhaave to a genus of plants, the characters of which are thefe. In the male flower, the cup is a perianthiurn of the bignels of the flower, com- pofed of five oval obtufe leaves, which are hollow, and ftand open. The flower is compofed of five petals, which ftand very wide open, and are of a cordated figure, with plain ungues, fhorter than the cup.

The internal ncctaria ftand between the others, and are a fmall fort of glands, with an aperture, difcharging honey at their tops. The ftamina are fVe filaments, placed within the ftile, and Handing at a diftance from the petals : the antherae, which thefe fupport, are round, and turn about upon them : the piftil has no germen : the ftile is very long, of a cylindric figure, and truncated, and produces the ftamina in its middle. In the female flower, the perianthiurn and the petals are the fame as in the male ; but the external nectaria are only dou- ble, and appear roundifh. Their fize and fituation are the fame as in the male, and there are in thofe flowers no internal nectaria The piftil is a roundifh germen, crowned with three bifid ftilcs of the length of the flower, and thefe ter- minated by obtufe ftigmata.
