Ecuapor: epiphyte, island in Lake Cuicocha, Province of Imbabura, 
at 3100 meters altitude, “leaves thick, dark green above, bronze 
beneath, sepals pinkish white, petals narrow and white, labellum 
white with yellowish center, slightly fringed, column pale pastel 
green,’ May 29, 1939, Penland & Summers 756 (Tyrer in Herb. Ames 
No. 57881). 
Epidendrum Penlandii is closely allied to 7. conopseum 
R. Br., a species which occurs in the southern United 
States, with a variety in Mexico, but differs in the calli 
of the lip, in having smaller flowers and larger leaves. 
The outline of the segments of the flowers is almost iden- 
tical in the two species. [t is interesting to find a species 
in Ecuador which is so similar to a species of the southern 
United States and Mexico.
