of the ventral side, gradually tapering to a fine acuminate 
point, strongly reflexed when mature; stamens very numerous, 
with the petals inserted upon the calyx rim; filaments glab-

A powerful climber in dense wooded jungles at 3000 feet

Very close to my R. benguetensis, but the calyx is not dense- 
ly tomentose, stamens and pistils twice as long, petals pres- 
ent, stipules not entire, and inflorescence more corymbosely 
paniculate.
