NEW AND SIGNIFICANT SPECIES OF PLEUROTHALLIS 
FROM OAXACA 
Tue following species of Pleurothallis were collected 
by the writer in the northeastern part of Oaxaca, Mexico. 
Specimens of the collections are preserved in the Ames 
Herbarium. The following notes are presented in view 
of the fact that the collections represent undescribed or 
rare orchids which add to our knowledge of distribution. 
Pleurothallis Grobyi Bateman ex Lindley in Bot. 
Reg. 21 (1836) t. 1797. 
Mexico: Oaxaca, District of Cuicatlin, Cerro Machin, San Juan 
wOe 
Zautla, long. 96°40’, lat. 17°58’, altitude 450 m., June 29, 1939, 
Schultes 739. 
The range of Pleurothallis Grobyi is very wide, in- 
cluding Central America, South America as far south as 
Brazil, and the West Indies. It has been known from 
Mexico by collections made in Vera Cruz and in Chiapas. 
It is especially well represented in the Ames Herbarium 
from Chiapas. Schu/ltes 739 is the first collection reported 
from Oaxaca and extends the range of the species consid- 
erably northwestward.
