Cymbidium Corallorhizon, Sp. pi. 4. 109. 
Root tuberous, branching, divaricate. Stem twelve to fourteen inches 
high, glabrous, clothed with sheaths which at the summits are abruptly 
acute, the upper frequently terminating in a subulate leaf nearly an inch 
long. Flowers in a terminal raceme, nodding. Segments of the periantk 
oblong lanceolate, connivent; of an obscure purplish brown colour; lip bi- 
dentate near the base, with the teeth inflected. Column much shorter than 
the petals. 
Grows in rich wooded lands. I have specimens sent me from Boston by 
Dr. Bigelow, and some collected at St. Mary’s, Georgia, in which I can dis- 
cern no difference.
