(type in Gray Herb.; duplicate in herb. N. Y. Botanical Garden; 
photog. and fragm. in U.S. Nat. Herb.). 
The type collection has been identified as Verbesina arborea 
H. B. K., but that plant has an unwinged stem and different 
pubescence. V. brachypoda is nearer V. callacatensis Hieron., 
which has a densely hirsutulous involucre and longer, auriculate 
petioles, and the wings of the stem, when present, are much less 
developed in that species.
