margins and more oblong diverging lobes, by the very narrow 

 petals, and the keeled anther. The flowers, too, are more nume- 

 rous, and crowded into a loose head, like that of C. calanthoides, 

 Kranz. The broad leaf and numerous flowers also distinguish it 

 from O. purpurascens, Thouars. The stem is about 10 inches in 

 height ; the radical leaf 3 inches in length by f in the broadest part. 

 The bracts are | of an inch, the ovary nearly 2 inches long, 

 distinctly pedicellate. The lip is % of an inch long, | an inch across 

 the lower lobe. Its edges at the base are reflected and attached 

 to the lower part of the stigmatic arms, thus forming a tube 

 to the entrance of the straight spur, which is 1| inch long.
