The flowers apparently white. This is allied to B. 

 Rohinsonii, Ridley; but the leaves are quite equilateral and not 

 bilobed. It evidently creeps on tree trunks as does that 

 species, as one specimen shows roots spread out from the 

 rhizome with moss on them.

This species is allied to B. speciosa, DC. & Planch., but is 

 very distinct in its much smaller, more slender inflorescence, 

 and longer peduncles.
