This subspecies can be easily distinguished cent to -puberulous on the veins, occasionally
from subsp. scobina by the arachnoid indument brown, pluricellular hairs on the main veins,
covering the smaller veins (between the parallel arachnoid hairs in the areoles, often also on the
tertiary veins), and often also by the relatively smaller veins; lateral veins ca. 15-30 pairs, terbroad
segments of the lamina. Some of the spec- tiary venation almost plane beneath; petiole 8-
imens are yellow-hirsute on the leafy twigs, or 50 cm long, glabrous or occasionally with brown,
also on the stipules, petioles, main veins of the pluricellular hairs; stipules 2-20 cm long, outside
lamina above and/or the peduncles. Such spec- white-appressed-puberulous and with (dense) redimens
resemble P. oraria very much. The two brown, pluricellular hairs, inside densely yellowtaxa
differ in the smooth upper surface of the hirsute and sometimes with brown, pluricellular
lamina, the smooth fruiting perianth, and the hairs, caducous. Staminate inflorescences up to

Distribution (Fig. 68). Extending from Colombia
(Meta) through Amazonian Ecuador, Peru,
and Brazil (Acre and western Amazonas) to Amazonian
Bolivia, also in Amazonian Venezuela;
in non-inundated forest, at altitudes up to ca.
1000 m. Often cultivated and their occurrence
often indicating previous human inhabitation.
