Martius FI]. Bras. 3, pt. 1 (1868) 357. 
A rather abundant though highly localized little plant, 
Paepalanthus fasciculatus seems to occur on the sandy 
savannas or caatingas of both cretaceous quartzite and 
cambrian granite origin—one of the relatively few spe- 
cies common to the floras of both of these geological 
areas in the northwestern Amazon. It is a species of the 
northwestern Amazon Valley and the upper reaches of 
the Orinoco.
