This species is manifestly allied to the form described some years ago 
as Dimorphocalyx longipes Merr., which is better placed in Trigonostemon. 
It differs remarkably in its caudate-acuminate, larger leaves and especially 
in its very prominent, leaf-like bracts. Opportunity is here taken to 
transfer Dimorphocalyx longipes to Trigonostemon:
