NEW OR INTERESTING ORCHIDS FROM 
ECUADOR AND COLOMBIA 
Durine 1989, C. William Penland and Robert H. 
Summers of Colorado College undertook botanical ex- 
ploration in Ecuador. The orchids collected consisted of 
136 numbers, mostly in duplicate. Among these there 
were a few apparently undescribed species. Several collec- 
tions, other than those of Penland and Summers, have 
been included in this paper because of their relation to 
the Penland and Summers specimens.
