Several ecotypes of var. elongata are known. The typical form has stems pilose with widely descending setae and is matched by modem collections from near Niquelândia and Cabeceiras in Goiás. From Sobradinho in the Federal District comes a more slender form with appressed-strigose stems (Irwin 11433, 11443a, NY); and from neighboring Minas Gerais (mun. Burití, 200 km e. of Brasília, Irwin 5471, NY) a glabrescent form with glaucescent leaflets.
