Diothonea lloensis, Lindl., is the original species of an ROSE 7 
base of the lip is attached and from which the limb of the same is 
more or less sharply reflexed ; also in the prominent almost hooded 
clinandrium and in the possession of a viscus connecting the pollinia. 
The species was first collected in the Valley of Lloa by Colonel Hall,

and the subsequent gatherings ai tt and Hartweg were made 
in almost the same locality —R. A. RoLFE.
