There being no specimen of this species in the Herbarium of 

 Ruiz and Pavon, and as the plant has been only known by the 

 short specific character contained in the work above-quoted, I 

 have thought that the above description, derived from the ma- 

 nuscripts of Ruiz, might not prove unacceptable to my botanical 

 readers.

squamis
