In connection with his description of this new species, 
Leonard writes: 
The leaf blades of Ducke’s material are more ovate and less rounded 
at the base than are those of the type. 
The type plant, Schultes informs us, is a rampant liana clambering 
over grasses or low shrubs. Only one plant was observed. The specific 
epithet is derived from Adsios, shaggy, and #vrov, plant, and alludes 
to the densely fulvous-tomentose inflorescence, young leaves, and 
stem tips. 
This new species resembles and is probably closely related to Men- 
doncia gigas Lindau. The size and shape of the bracts and the nature 
of the pubescence covering them and the peduncles are much the same 
for the two species. The leaf blades, however, of Mendoncia gigas are 
generally smaller, not exceeding 13 cm. in length and 7 em. in width, 
and no mention is made of the suborbicular type of leaf sometimes 
subtending the inflorescence. Again the calyx of Lindau’s species is 
described as puberulous, whereas in Mendoncia lasiophyta it varies from 
glabrous to sparingly long-pilose. The corolla lobes of Mendoncia gigas 
are larger, 6 to 7 mm. in diameter instead of 4 mm. long and 3 mm, 
wide, and their tips are rounded instead of emarginate. Finally, the 
ovary, pronouncedly puberulous in Mendoncia gigas, is definitely gla- 
brous in M. lasiophyta. 
A photograph of Ule 9800, the type of Mendoncia gigas, is in the 
U.S. National Herbarium, The type was collected at Seringal Auris- 
tella, along the Rio Acre in Perit.
