On the evidence of the descriptions of Centropetalum 
Warscewiczii combined with the analytical drawing cited, 
it appears that this concept cannot reasonably be sepa- 
rated from the earlier C. distichum which is represented 
in the Gray Herbarium by authentic material and in the 
Ames Herbarium by a photograph of the type with floral 
analyses. Indeed, the only discrepancies to be found are 
that the lip of C. Warscewiczi is lightly retuse in con- 
trast to the entire (or denticulate) apex of this organ in 
C. distichum, and the color of the flowers which is desig- 
nated as purple or blood-red in C. Warscewiczti, as con- 
trasted with yellow or orange-yellow in C. distichum. On 
the sheet bearing the photograph of typical C. distichum, 
however, there is one lip (of an Ecuadorian plant) show- 
ing a similarly retuse lip. Thus the slight discrepancy in 
color appears to be the only remaining difference. 
The name Fernandezia must be considered to be in- 
valid, because this genus (as illustrated in Ruiz & Pavon 
F]. Peruv. et Chil. Prodromus (1797) t. 27, Fernandezia) 
comprises at least two different genera. 
In describing the concept Fernandezia pulchra (1.c.) 
Schlechter says that it differs from Centropetalum disti- 
chum in having larger flowers of different color, in the 
form of the lip and its callus and in the toothed and 
8-lobed clinandrium. However, the photograph of typi-
