Hitherto only one species of this genus has been descrilied, the P. distichum of the 

 Hmb, and Knih. Nov. Gen. et Sp. n, 1. t. 77., an inhabitant of Loxa and Gonzana in 

 Peru. Froni that our plant is abundantly distinguished by ils much slenderer stenns, 

 smaller and by no means falcate leaves, by ihe few (apparenily constantly) S-flowered 

 spikes. The scpals are singulnrly (fig. 4!) grooved and carinaled. ihe labellum (scar- 

 cely differing in form from ihe pelals) is destitute of lubercles. which have been con- 

 sidered an essential character of the genus ; but Prof. Lindley doubts whether those 

 represenied by Humboldt are not so done by mistake.
