Lindleys sketch which accompanies the type exhibits aperfectly smooth flower, as figure 2, plate 72 shows. In all otherrespects this sketch suggests the flowers of H. adenantha Gal. Dr. Prain, in a communication received December 17,1909, assures me that the flowers of Habenaria crassicornisare, in Lindleys original specimen, covered with little roughpoints.
