lip-claw and lateral lobes nearly as abrupt as those in the 
concept Lindleyella. Furthermore, Lindleyella auranti- 
aca is the only species of that genus to conform with 
Schlechter’s requirements. All of the other species so far 
referred to Lindleyella (L. bicornaria (Reichb.f.) Schitr., 
L. floribunda Schltr., L. picta Schltr. and L. saxicola 
Schltr.) have a short or very short claw to the lip, less 
abrupt lateral lobes and an additional callus near the 
claw. Finally, the concept Lindleyella shows the same 
short mentum exemplified by the type species of Bifren- 
aria (B. atropurpurea (Lodd.) Lindl. ). 
Therefore, since there is such a close vegetative simi- 
larity, as well as a general morphological agreement of 
the floral segments and even of pollinia, between these 
concepts and species of the genus Bifrenaria, I find it 
impossible to accept Lindleyella as a valid segregate. 
In conformity with these views, the following trans- 
fers become necessary : 
Lindleyella floribunda Schltr. (in Fedde Repert. Beih. 
27 (1924) 84) = Bifrenaria floribunda (Sch/ltr.) C. 
Schweinfurth comb, nov. 
Lindleyella picta Schltr. (in Fedde Repert. Beih. 27 
(1924) 1783; ex Mansfeld in Fedde Repert. Beih. 58 
(1930) t. 50, nr. 200)= Bifrenaria picta (Sc//tr.) C. 
Schweinfurth comb, nov. 
Lindleyella saaicola Schitr. (in Fedde Repert. Beih. 
27 (1924) 143) = Bifrenaria saxicola (Sch/tr.) C. 
Schweinfurth comb. nov. 
In the Ames Herbarium (No. 26989), there is a spec- 
imen labelled Lindleyella picta Schltr. from near Buena- 
ventura, Colombia, sent by C. W. Powell and determined 
by Dr. Schlechter. Since these data are cited under the 
type description, this collection may reasonably be con- 
sidered to be an isotype. The flower is a close approxi-
