 in pots or in the open ground. 



II. BULLIA'RDA (in memory of Bulliard, author of

LIN. SYST. Tetrdndria, 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 Crdssula in the form of the scales, and from 

 Tillce'a in the many-seeded carpels, as well as in the number 

 of the parts of the flower.

winter ; tubers roundish ; fibres capillary. Stems simple, te- 

 rete. Leaves of 2 opposite pairs, and the pairs sometimes 

 approximate so near as to make the leaves appear in whorls. 

 Flowers white, disposed in something like umbels. The habit 

 of the plants is referrible to some Saxifragece. 



1 S. CAPE'NSIS (Lin. amcen. 6. p. 8 7.) leaves roundish, broadly 

 crenated, tapering into the petioles ; and the base of the petioles 

 is rather connate ; petals spreading. If. . D. G. Native of the

 p. 291. There are varieties of this plant, differing in the num- 

 ber of the floral parts from 5-9, but generally 7 ; and with few- 

 flowered or many-flowered umbels ; and with leaves more or less 

 stalked, having the crenatures either simple or subcrenated. 

 Flowers white or red.

Umbelled Septas. Fl. July. Clt. 1800. PL | foot. 



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.
