Discussion:
The second known species of Oreanthes, described above, differs from O. buxifolius Benth. in its conspicuous and slender pedicels, the copious hispidglandular pubescence of its flowers (present also but less obvious on other parts of the plant), its comparatively short and essentially free filaments, and its differently proportioned anthers, of which the thecae are much shorter. The genus Oreanthes remains an extremely rare entity in collections. It is apparently restricted to Ecuador, but since noting only the type collection of O. buxifolius in my 1932 treatment (Contr. U. S. Nat. Herb. 28: 359), I have seen two other collections of that species, Penland 62 (NY) from Loja and 1180 (NY) from Tungurahua.
