the Ames Herbarium referred to that species, Brassia 
Lewistt cannot be separated from the widespread and 
variable B. caudata. The former concept, the habitat of 
which was unknown, does not show a single appreciable 
difference. The relative length of the petals and lip, 
sometimes relied upon for the separation of B. caudata 
from £B. Lewis, is a very variable character even in a 
single collection and, therefore, appears to be of no spe- 
cific weight. 
Brassia caudata extends from southern Florida, the 
West Indies and Mexico through Central America and 
most of the countries of northern South America as far 
south as Peru (Dept. of Loreto) and Bolivia. 
Brassia Forgetiana Hort. ex Gard. Chron. ser. 
3, 48 (1910) 434, 463, 471, fig. 209, nomen tantum. 
This concept, which is one of the Peruvian discoveries 
of the late collector M. Louis Forget, made its first ap- 
pearance in The Gardeners’ Chronicle (l.c.) where the 
brief diagnosis is chiefly confined to remarks on the color 
of the flowers. The excellent figure which appears on p. 
471 of that volume has a revealing floral analysis which 
would have been regarded as evidence of satisfactory pub- 
lication if it had appeared two years earlier (according 
to the International Rules of Botanical Nomenclature). 
Since there is apparently no subsequent diagnosis to vali- 
date this concept, I now propose to furnish both a Latin 
diagnosis and a detailed description (so that the concept 
can take its place among validly described and under- 
stood species).
