This species differs from D. oppositifoJius, the only previously known species 

 in the genus, in size and shape of the leaves and of the calyx and in the posture 

 of the corolla-lobes. It differs also in having strikingly horned fruits which have 

 only a single ridge on the back, rather than two as in D. oppositifolius (fruits 

 of var. congestus have not been seen but they are very likely similar to those of 

 the typical variety). The specific epithet is intended to call attention to the 

 horned fruits. 



Var. congestus has the leaves somewhat smaller and congested at the branchlet 

 tips; these plants also have shorter petioles, a pubescent calyx, and usually a 

 puberulous corolla. 



Galipea stelligera Cowan. 



VENEZUELA: Amazonas: Cerro Yutaje, Jan-March 1953, 1300-2000 m elev., Maguire

These are the first collections subsequent to the description of this species 

 from Cerro Duida, more than 100 miles to the south. This extension of range 

 suggests that the species may be expected on other of the sandstone mountains 

 in western Venezuela.
