This is the first record of the genus Stenopadus from 
Colombia. In Maguire’s treatment (Mem. N.Y. Bot. 
Gard. 8 (1953) 1538), Stenopadus colombianus would come 
nearest to S. talawmifolius Blake and S. cardonae Mag. 
& Lasser (=S. talaumifolius var. magnifolius Steyer- 
mark). From both of these species it differs in its much 
larger leaf-blades, more numerous flowers in a head, 
nearly glabrous involucre, the squamo-strigosity of the 
branches and petioles, and the sparsely dispersed mal- 
pighiaceous hairs on the leaves.
