Discussion:Although Bentham described the corolla-lobes as ''intus fere glabri," an examination of an isotype specimen (Schomburgk 578) shows the interior of the corolla-lobes to be densely puberulent. In all other respects his description applies to the characters evident on the isotype. The lower surface of the leaves of the type collection have moderately to densely pilose midrib and lateral nerves, and the lower surface itself, while mostly glabrous, m a y have a scattering of pilosulity. The axils of the lateral nerves at their junction with the midrib on the lower surface are rather noticeably barbate in the type collection. This barbate condition varies, as it is not present in the 3Iaguire-Fanshawe 23185 collection, but is obvious in the Steyermark 59339 collection and other collections cited.
