Distribution and Ecology - Distribution. Known only from southwestern Venezuela. VENEZUELA. Amazonas: occasional in montane cafio savanna, Cerro Moriche, Rio Ventuari; alt. 800 m ; 14 Jan 1951, Maguire, Cowan, & Wurdack 30886 (holotype NY); Puerto Ayacucho; 31 Sep 1960, Foldats 3602 (VEN).

Discussion:

This variation of var. hispida has the hairs on the stems, leaves, and calyx gray or white instead of buff, stramineous, or ochroleucous at the base as in typical var. hispida. In typical var. hispida the hairs on the leaves are weaker, more laxly spreading, and often much sparser.

The holotype has the thickish leaves covered on both sides with rigid short hairs pointing to the apex. In the collection of Foldats 3602 the leaves have less rigid and longer hairs and the leaves are thinner with 2-4 weak nerves on either side of the midrib. In the holotype collection the leaves have 1-3 strong elevated nerves below.
