 funnel-shaped, very minutely furfuraceous without ; tube scarcely 

 1 J lin. long, glabrous in the throat ; supra-staminal calli transversely 

 linear ; lobes rather thick, ovate-lanceolate, as long as the tube or 

 slightly longer. Staminal cone reaching to the corolla-mouth ; anthers

Flowers sometimes occur with the tails of the corolla-lobes not developed. Such 

 flowers are very like those of B. elUptica. De Wild. & Durand quote (Reliq.
