by cuttings or seeds. They are well fitted for rock work, or to 
be'grown in small pots among other alpine plants.

cleft (f. 23, a.), permanent ; segments concave, keeled, mucronate 
at the apex. Petals 5 (f. 23. b.), emarginate, inserted in the 
tube of the calyx. Stamens 3-5, inserted in the tube of the

8-valved (f. 23. e.), many-seeded. Seeds nearly ovoid, a little 
Curved, fixed to the central placenta.—Annual, branched, dicho- 
tomfous herbs. Leaves opposite, or 4 ina whorl; young ones 
usually disposed in fascicles in the axils of the old leaves. 
/Owers in cymose corymbs. Stipulas and bracteas small, sca- 
Tlous.—This genus agrees with Adendrium, but differs in the 
Stamens being equal in number to the petals, not as in Caryo- 
phyllee, double that number. 
* Flowers triandrous.

Cult. The seeds of the annual species of the genus only 
require to be sown in the open border in spring. The last spe- 
cies being perennial, should be grown in a small pot, and placed 
among other alpine plants.
