Cæsalpinia. Leguminosæ.
Increased by cuttings, which are somewhat difficult to root, but may succeed if taken from the plant in a growing state and planted in sand with a hand-glass over them, in heat.
Cajanus. Leguminosæ.
Plants are usually raised from seeds obtained from the West Indian Islands and India. Also grown from young cuttings, put in sand with a hand-glass over them, in heat.
Cakile (Sea Rocket). Cruciferæ.
Propagated by seeds sown in spring.
Increased by tubers, which have been kept dry or rested for some time. Place in small pots in a stove or pit, where the night temperature is maintained from 60° to 65°, and syringed daily once or twice at least. Large tubers, if sound, may be divided and the pieces potted. Some also by cuttings.
Calamagrostis. Gramineæ.
Increased by seeds sown in autumn or spring. C. arenaria (now Ammophila arundinacea), used for holding sands along sea-shores, is propagated by division and can probably be handled easily by root-cuttings.
