3-5 mm. long., deorsum -5 mm. lat. Filamentorum pars inflata 

 1 mm. long., pars altera filiformis, 1 mm. long. ; antherae ovoidesB, 

 sursum attenuatae, stylum brevem longe superantes, 2 mm. long. 



Differs from B. angolensis N. E. Br. chiefly in the less broad 

 leaves markedly narro\Yed below, the small flowers with shorter 

 and broader calyx-segments, the much shorter corolla lobes, the 

 filaments filiform in their upper part (not broadly oblong), and the 

 short staminal column.

One of Whyte's specimens is in fruit, bearing follicles which 

 are ovoid-oblong below, gradually narrowing above to the obtuse 

 apex, nearly 5*5 cm. long, and about 1 cm. broad below and 

 2- 3 mm. close to the top ; under the lens they are finely pulveru- 

 lent -puberulous. The seeds are oblong, shortly beaked, dark 

 brown, and scaberulous, with a 24 mm. long coma.
