 1-3 m. high, occasional, summit of East Escarpment at 1900 m. alt., 30116; small 

 tree 4 m. high, involucral bracts dark wine-red, anthers brownish-red, stigmas

Stenopadus huachamacari and S. kunhardtii both belong to the subgenus Eus- 

 tenopadus Blake, closely related between themselves and with 5. connellii (N. E. 

 Brown) Blake of the eastern portion of the Guayana Highland, which has densely 

 tomentulose branchlets, broadly elliptic very prominently nerved leaves with 

 obtuse bases, and somewhat smaller flowers some 3 cm. long. The two species 

 here described are superficially very similar, but are distinguished by numerous 

 characters, the most obvious being the non-stipitate heads and narrower smaller 

 leaves of S. huachamacari, as contrasted with the stipitate heads and larger 

 broader leaves of S. kunhardtii. 



Stenopadus crassifolius Blake.
