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 :
