The thin foliage, combined with an exceedingly slender tortuous habit, distinguishes 
this species.

In habit, foliage, and inflorescence this species closely resembles the North-American 
D. cuspidatum, Torr. & Gray (D. bracteosum, Michx.); but the latter wants the cordate 
stem-clasping stipules and the folded pod of our plant, which also differs in its leaflets, 
smaller flowers, and bracts.
