A comparison of the Bolivian species L. Rusbyi, as 
represented by a photograph of the type, with the Peru- 
vian 1. ramosa, as shown by the plate of the type (l.c.), 
indicates that the two concepts are inseparable. Liparis 
Rusbyt appears to have somewhat larger flowers than 
those of the Peruvian collections referred to L. ramosa.

A comparison between M. auropurpurea, of which we 
have authentic material, and the Bolivian 7. Herzogu 
(illustrated by a floral analysis of the type) shows that 
the concepts are synonymous. Kriinzlin, in his monograph 
of Masdevallia (in Fedde Repert. Beihefte 34 (1925) 128), 
regards this concept as a synonym of Masdevallia brachy- 
ura Lehm. & Kriinzl. which he keeps separate from MZ. 
auropurpurea. We have seen no good material of M. 
brachyura. However, it seems probable that it may prove 
to be merely a small form of M. auropurpurea. 
Furthermore, it appears that M. wanthura differs from 
M. auropurpurea only in having longer tails to the sepals 
and in having yellow and violet, instead of yellow and 
brown, flowers. The bilobulate apex to the petals found 
in this concept also occurs in M. auropurpurea. It there- 
fore seems unjustifiable to maintain M. wanthura as a 
distinct species.
