Buchtienia boliviensis Schlechter in Fedde Repert. 
27 (1929) 34. 
This monotypic genus, originally limited to Bolivia, 
has lately been recognized from Peru. The collection 
cited is somewhat lower in stature than the type. It 
shows one leaf about 48.4 cm. long (in contrast to the 
cited maximum length of 40 cm.), while the lamina, 
which is oval, rather than elliptic or elliptic-oblanceolate, 
has a maximum length of 23.5 em. (as contrasted with 
22 cm.), and a maximum width of 13 cm. (in comparison 
with 10 em.). Moreover, the base of the blade appears 
to be sometimes subcordate and not cuneate as cited. 
The flowers of the Peruvian collection are noted as rose- 
colored, whereas those of the Bolivian type are designated 
as greenish. The parts of the perianth are very similar in
