Habenaria graciliscapa is an interesting addition to 
the orchid flora of both Argentina and Uruguay from 
which countries it has been sent to me by Dr. H. R. 
Descole and Dr. Bernardo Rosengurtt. 
The orchids of Argentina and Uruguay are not very 
great in number when contrasted with those of other 
areas in South America; seldom, however, does a collec- 
tion from these countries come in for determination that 
does not contain some rare, noteworthy or new orchid. 
It is quite probable that this will continue to be true for 
many years.
