Danert’s suggestion (5) that D. suaveolens and D. 
candida may be conspecific deserves further consideration 
and, especially, experimentation. However, the associa- 
tion in .D. suaveolens of several characters rarely seen in 
D. candida and the relatively very few intermediate 
specimens known, imply, at least for the present, that 
both concepts are of species status.

DovusTrrulL SPECIES AND HYBRIDS 
D. vulcanicola A.S. Barclay in Bot. Mus. Leafl. Har- 
vard Univ. 18: 260 (1959), closely related to D. san- 
guinea R. & P., is distinguished by its cernuous flowers 
with light red throat, yellow mouth and red nerves, and 
by its warty, almost woody, fruit with smooth seeds.
