So called from the two furrows on the dorsal surface of the 
leaves and sepals.

Habit of Cherleria sedoides. The specimens from Guatemala 
deseribed by Mr. W. B. Hemsley do not seem to differ materially 
from the type, except in the somewhat tougher sepals.

Syn. A. serpens var. Orizabe, Rohrb. in Linnea, xxxvii. p. 271. 
The specimens of this variety are labelled Cherleria serpyllacea 
Presl, in Haenke's herbarium. There is also an additional note 
that they were from the Peruvian Andes. Rohrbach is disposed 
to doubt that Haenke procured these specimens from Peru, and 
a posteriori does not admit the extension of the range of the 
species to South America. The leaves are larger than those of 
the type, but not so smoothly shining. 
Hab. Mexico: no locality (Uhde no. 1104, Schaffner no. 489,
