albuminous ; cotyledons flat, fleshy.—Trees or shrubs, erect or scan- 
dent, the extremities or intlorescence occasionally cirrhose. Leaves 2-

species caducous or inconspicuous. Flowers 2 or 3 together on leaf- 
opposed or terminal peduncles, or collected in simple or compound 
corymbs racemes or panicles, white or rose to purple and yellow.

1. B. fassoglensis, Kotschy; Schweinf. Rel. Kotsch. 14, t. 12, 13. 
Extremities glabrescent, at first thinly pilose with appressed rusty 
deciduous hairs. Leaves firmly membranous, suborbicular, 2$—4$ in. 
broad, with a deep often narrow basal sinus; leaflets connate three- 
fourths of their length or more, rounded above and below, each with 
4 divaricately forking nerves, glabrous or nearly so, paler or subglaucous 
beneath. Flowers in pedunculate terminal or leaf-opposed, rather lax 
many-flowered simple racemes, with the peduncle 9 in.—1 ft. long. 
Bracts lanceolate or subulate, 2-3 lines long, deciduous. Pedicels 3-2 
in., ascending, recurved at the apex, at least in bud. Calyx rusty- 
pubescent, deeply 5-fid, lobes oblong-lanceolate, acute, all strongly 
carinate, twice or thrice as long as the short campanulate tube. Larger
