ON AMERICAN ORCHIDS 
BY 
CHARLES SCHWEINFURTH 
TuE following notes were assembled during the work 
of identifying various tropical American collections and 
particularly in the course of preparing an intensive orchid 
flora of Peru. 
The sequence of genera follows the System of Classi-

Botanischen Gartens und Museums Berlin-Dahlem, 
Band 9, Nr. 88 (1926) 567-591. 
Habenaria repens Nuttall Gen. N. Am. PI. 2 (1818)

Platanthera foliosa Brongniart in Duperr. Bot. Voy. 
Coquille, Phan. 195 (1829) t. 88B. 
Habenaria mawvillaris Lindley in Hook. Journ. Bot. 1 
(1834) 5; Gen. & Sp. Orch. (1835) 310.
