Herbier de la France, 600 planches in fol. 1780, and other 
botanical works). D.C. bull. philom. no. 49. p. 1. prod. 3. p.

Lin. syst. Tetrándria, Tetragynia. Calyx 4-parted. Petals 
4, oval or oblong, acute. Stamens 4. Scales 4, linear. Car- 
pels 4, many-seeded.—Small, glabrous, annual, subaquatic herbs. 
Leaves opposite. Flowers small, white, axillary, sessile, or pe- 
dicellate. The parts of the flower are sometimes quinary, and 
therefore differ from Crassula in the form of the scales, and from 
Tillæ'a in the many-seeded carpels, as well as in the number 
of the parts of the flower.

Cult. A mixture of sand, loam, and peat suit the species of 
this genus; and they should be watered but sparingly when not 
in a growing state. They are readily increased by separating 
the tubers of the roots.
