membranous, about an inch long, oblong-lanceolate, 1-nerved, arch- 

 veined, tapering at the base, mucronate at the apex, serrate, serratures 

 mucronate, mucros curved. Petioles 4-6 lines long, terete, chan- 

 nelled on the upper surface and furnished at the margins with nume- 

 rous stipitate glands. Stipules linear-subulate, nearly as long as the 

 petioles. Peduncles axillary, about twice the length of the leaf-stalks, 

 dividing above into 2-3 bracteate divisions, of which one only bears a 

 flower. Bracts linear-subulate, like the stipules, about 2 lines from 

 the flower. Flower erect, bell-shaped, whitish, 4—6 lines long. Flower- 

 tube very short. Sepals herbaceous, 3-4 times longer than the tube, 

 linear-oblong. Petals membranous, white, many-nerved, rather shorter 

 than the sepals. Intermediate row of corona membranous, spreading 

 or deflexed, about one-fourth of the length of the outer row ; third row 

 of tbe corona rather longer than the second row. Filaments flat, 

 ribbon-shaped, 1 -nerved, dilated at the base, attached to the back of the 

 linear anthers by a narrowed extremity. Ovary ellipsoidal, glabrous, 

 raised on a short stipes or subsessile ; styles consolidated for three- 

 fourths of their length, dividing above into 3 stigmatic branches. Cap- 

 sule nodding, \ in. long, smooth, obtuse at both ends.

Flowers dichlamydeous, hermaphrodite. Flower-tube short, deeply 

 divided into 5 oblong-lanceolate overlapping segments. Petals 5, 

 springing from the edge of the flower-tube. Corona of two rows 

 emerging from the throat of the flower-tube ; outer row membranous, 

 jagged at the edge, about half the length of the petals; inner row 

 much smaller, consisting of a ring of thick fleshy tubercles. Stamens 

 numerous, monadelphous at the base, emerging from the base of the 

 flower-tube ; filaments in two rows ; anthers linear-oblong, introrse. 

 Ovary sessile, globose ; styles consolidated ; stigma large, mushroom- 

 shaped. Fruit coriaceous, indehiscent, globose. Seeds ovoid, com- 

 pressed ; testa pitted. — Trees or shrubs with large leathery leaves and 

 numerous flowers arranged in dense axillary or supra- axillary tufts, 

 surrounded by overlapping bracts. 



A genus comprising two species only, and confined to Western Tropical Africa.

1. B. nigritiana, Hook.f. in Journ. Linn. Soc. v. 15, t. 2. A small 

 tree or shrub* with stout branches, covered with rusty down, and 

 marked on either side with a raised line continuous with the base of 

 the leaves. Leaves coriaceous, glabrous, 6—10 in. long, 2-3 in. wide, 

 oblong, subacute, crenulateor entire, unicostate, rounded at the base or 

 tapering into a short thick leaf-stalk. Stipules deciduous. Flowers large,
