*1. B. TOMENTOSA L. 
An erect, branched shrub 1.5 to 3 m high, the branchlets, lower surfaces 
of the leaves, and the pods somewhat pubescent. Leaves 4 to 7 cm long, 
about as wide, split about one-third to the base into two, ovate, rounded 
lobes. Flowers pale-lemon-yellow, usually in pairs on axillary peduncles. 
Calyx-limb spathaceous, split down one side. Petals about 5 cm long, 4 
em. wide. Stamens 10, all fertile, unequal in length, the filaments 1 to 
2 cm long. Pod 9 to 11 cm long, about 1.5 cm wide, flattened, acuminate, 
containing 6 to 10 seeds. (FI. Filip. pl. 119, B. binata.) . 
Cultivated for ornamental purposes, fl. most of the year. A native of 
India, now rather widely distributed in the tropics in cultivation and as 
an escape. 
2. B. ACUMINATA L. 
An erect shrub 2 to 4 m high, somewhat pubescent. Leaves 7 to 13 
em long, 6 to 12 em wide, base somewhat cordate, 9- to 11-nerved, the lobes 
acute or slightly acuminate, about one-third the length of the leaf. Ra- 
cemes axillary, short, few-flowered. Calyx green, about 3 em long, split 
down one side, acuminate, the apex with 5, short, slender teeth. Corolla 
white, about 8 cm in diameter. Stamens 10, shorter than the petals, all 
acuminate, glabrous, containing 7 to 9 seeds. (FI. Filip. pl. 111.) 
In dry thickets opposite San Pedro Macati, also cultivated, fl. Aug.—Oct.; 
of local occurrence in the Philippines; and surely introduced. India to 
China and Malaya. :
