NOTES ON PERUVIAN ORCHIDS 
BY 
CHARLES SCHWEINFURTH 
THE examination of loans obtained chiefly from the Pres] 
Herbarium at Prague by Mr. Leslie A. Garay of the 
University of Toronto has revealed the necessity of mak- 
ing several changes in nomenclature. 
HaBENARIA LINIFOLIA Presl Reliquiae Haenkeanae 
1 (1827) 91. 
The type collection of Habenaria linifolia, borrowed 
from Prague, is incomplete, showing only the upper por- 
tion of the plant including two leaves and a loosely flow- 
ered spike, but it definitely agrees with the description. 
The plant, however, resembles certain forms of Haben- 
aria dilatata (Pursh) Hooker. On examining a flower, 
moreover, which likewise matches the description, it was 
found that the lip exactly coincides with that of some 
forms of the latter species. 
Since Habenaria dilatata is a boreal species extending 
only as far south as New Mexico and California and has 
never been recorded from Central or South America, its 
occurrence in Peru seems well nigh incredible. More- 
over, it is a known fact that some of the species described 
by Pres] in the above work have been confused owing to 
mixed labels. It seems desirable, therefore, that Haben- 
aria linifola be reduced to synonymy and omitted from 
the list of Peruvian species.
