MDCCCXXXVIII.A genus of hot-house trees and shrubs, natives of the East and West Indies. Linnaean class and order Decandria Monogynia; natural order Leguminosae. Generic character: calyx five parted, lowest segment large and vaulted; corolla of five petals; stamens downy at the base; style filiform; stigma truncated and fringed; pod and seeds compressed. This family of plants is celebrated for the hardness and durability of its wood, and for its uses to the dyer. It makes the best trenails for ship-building. Both the C. crista and Brasiliensis yield the Brazil wood used in dyeing, though that of the C. echinata is said to yield the finest colour. The plants are thorny, and seldom flower in our stove; they are propagated by cuttings, but with difficulty.
