Habenaria Ghiesbreghtiana is closely allied to H. brevifolia, 

 and may be inseparable from it, but the material I have examined 

 has not been sufficient to warrant a definitive conclusion. The 

 leaves of H. Ghiesbreghtiana are 8.5 cm. in length on the type 

 specimen and somewhat spreading, thus differing from the leaves 

 of H. brevifolia which are rarely 7 cm. long and conspicuously 

 appressed to the stem. The specimen collected by Conzatti, cited 

 above, was compared with Richard's type, and agreed with it in 

 detail save as to leafage.

The type of this, a Mexican species {Galeotti no. 5257), consists 

 of a single individual 9 cm. tall, with lanceolate-triangular leaves, 



1 There is one individual of this at Paris and a drawing of a flower and bract, a Up and 

 column and a pollen-mass. (A. A. E.)
