The widespread species known as Scaphyglottis proli- 
Sera, illustrated by Lindley (as Isochilus prolifer, |. c.) 
is an entirely different plant from Mpidendrum prolifer- 
um Sw., upon which it was erroneously based. This con- 
cept, consequently, must have a new name. The next 
oldest designation not founded on Lpidendrum prolifer- 
um is selected, namely iS. cuneata. 
Except for Scaphyglottis Wercklei and its variety, the 
above names have already been reduced to synonymy 
(Correll in Bot. Mus. Leafl. Harv. Univ. 9 (1941) 148). 
Scaphyglottis Werckle: differs trom the typical form 
of S. cuneata only in lacking a callus on the lip. This 
structure, however, seems to be extremely variable when 
it is present and may be quite inconspicuous or lacking 
in certain collections. It seems advisable, therefore, to 
relegate both this concept, and its variety, to the poly- 
morphie WS. cuneata. 
This species occurs throughout Central America from 
Guatemala and British Honduras to Panama; in Gren- 
ada and Trinidad; and in Colombia, Venezuela, British 
Guiana, Surinam, Brazil, Bolivia and Peru.

Centralbl. 42, Abt. 2 (1925) 95. 
A number of collections from eastern Peru (Depart- 
ments of Junin and Loreto) have been referred to this 
species. Altogether they show marked variation in vege- 
tative size and in floral details, and accordingly it seems 
advisable to add a few supplementary notes to the orig- 
inal description. 
The lower part of the stems (even of the abbreviated 
superposed members) is clothed by several loose imbri- 
‘ating scarious evanescent sheaths, of which the upper 
ones are articulated to short blades. The leaves, which 
are gradually narrowed toward the apex, reach a length
