Discussion
The var. foliolosa differs from the common var. pubescens only in the soft spreading setose element of the pubescence, but this is visually striking. A sterile specimen (Burchell 7587. K) from near the present Tupiraçaba in central Goiás near 14°30'S suggests a considerable range-extension northward, but its foliage is atypically glandular.
