n many respects this plant corresponds with the description of 
M. lloensis Hieron., which, however, is said to have membranaceous 
5-nerved leaves with smaller teeth, a rufescent pubescence, and 3- 
nerved involucral scales—expressions far from applicable to the pre- 
sent plant. The achenes show, in somewhat marked degree, a ten- 
dency noticed elsewhere, namely that of having one or two false ribs 
or rib-like folds or angles in the surface between the primary ribs. 
Careful investigation shows these to be without vascular tissue and 
not of sufficient definiteness to warrant placing the plant in Kanimaa, 
which at best is a doubtful segregate from Mikania.
