Colvilea

(after Sir Charles Melville, governor of Mauritius). Leguminous. The gorgeous ls. of this tropical tree are a worthy rival of the Royal Poinciana, which is closely allied, but easily distinguished. It has drooping racemes 1% ft. long. densely crowded with perhaps 200 ls. of curious shape and of a splendid
scarlet. The flt. open at the stem-end of the pendent dense raceme, and display masses of long, showy, yellow stamens. The unopened fl. are about the size and shape
of a filbert, and these are gradually smaller towards the end of the raceme. The genus has only this one species, and is characterized by its large, oblique, colored calyx, having 4 segments, the standard being the small
est instead of the largest part; the wings very long,
narrow, erect, ob-ovate, the pod 2-valved. Supposed to
be a native of E. Afr., but discovered in 1824 by Boyer on the west coast of Madagascar. where a single tree was cult. by the natives. It flowered there in April or
May. its culture is similar to that of Caesalpinia. Prop. in the south only by seeds.

aspect of Poinciana regia but with a thicker trunk and
