SOME PERUVIAN MAXILLARIAS 
BY 
CHARLES SCHWEINFURTH 
DvRinG THE PROCcEss of working up the genus Max- 
illaria for the orchid flora of Peru, it has seemed advisa- 
ble to record the following taxonomic and nomenclatorial 
notes, amplifications and corrections of previous descrip- 
tions. Also, in accordance with our present practice of 
regarding the genus Ornithidium as referable to Maxil- 
laria, it has been necessary to make several new combi- 
nations. Furthermore, there are included the descriptions 
of six Maxillarias which appear to be new. 
Maxillaria alticola C. Schweinfurth nom. nov. 
Ornithidium serrulatum Lindley in Bentham PI. 
Hartw. (1845) 153, non Mawillaria serrulata Ames 
& Correll, 1943. 
In transferring the concept Ornithidium serrulatum to 
the genus Maxillaria, it should be noted that the epithet 
serrulata has been preoccupied and that therefore a new 
name must be used. 
The original description of Ornithidium serrulatum is 
very brief and by itself is inadequate to furnish a definite 
conception of this species. Fortunately, there are in the 
Ames Herbarium an excellent photograph of the type 
specimen bearing an analytical drawing of the flower 
made by Lindley and also several recent Peruvian speci- 
mens. Therefore, in order to clarify the species, a few 
supplementary notes are given herewith.
