 cellate flowers.

 Leaves glabrous, acuraiuate. Flowers on distinct pedicels, bearing a 



pair of connate deciduous bracts 1. B.. grandijlortu. 



Leaves more or less softly pubescent, at least on the under surface, ob- 

 tuse or acute. Flowers sessile or subsessile 2. H. senegolensu. 



1. H, grandiflorus, Benth. in Linn. Tram, xxiii. 468. t. 49. A tree, 

 attaining 60 ft., with the extremities glabrous, or at first sparsely pilose. 

 Leaves narrow-oval or oblanccolate, acuminate, thinly coriaceous, glal)rous or 

 with very thinly scattered hairs beneath, the midrib glabrous or puberulous ; 

 4-9 in. long, l|-2 in. broad ; petiole 2-4 lines. Flowers solitary or ia 

 pairs, on peduncles of \-\ in., bearing a narrow leaf-bud and a pair of rusty- 

 sericeous connate bracts. Sepals ovate, concave, thick and almost woodv in 

 texture, 4-6 lines long. Petals whitish, subequal, linear-lanceolate, trans- 

 versely plicate, silky-pubescent, 1^ in. or more in length. Anthers linear, 

 sometimes elongate, the connective obtuse or tinincate, scarcely prolonged 

 beyond the cells; filament much shorter than the anther. Carpels 10-12 ; 

 ovary densely pilose ; stigmas short, reflexed, 2-lobed ; ovules numerous, 2- 

 seriate. (Fruit-carpels 3-6, sessile, about 3 in. long, Ij in. thick, rusty- 

 pubescent-tomentose, rounded at the apex, with numerous seeds, transversely 

 packed, extending from side to side. It is not quite certain that the fruit 

 here described belongs to the same species.)

 shortly pilose or pubescent, at length glabrescent above, usually softly pubes- 

 cent beneath, the larger 4-5 in. long, 1-1 1- in. broad, subsessile or petiole 

 scarcely exceeding 1 line. Flowers cream-coloured, axillary, solitary or 2 or 

 3 together, with 2 or 3 deciduous concave bracts. Sepals ovate, pubescent

 cimens f-1 in. long). Anthers linear ; connective slightly transversely di- 

 lated, rounded or truncate; filaments short. Carpels 4-6. Fruit-carpels 

 sessile or subsessile, in our specimens 1-1 1- in. long, ^-1 in. thick, terete or
