n many respects similar to EL. solidaginoides HBK. but not as yet 
connected by intermediates and rather too different in appearance to 
be regarded as a variety until intergradation has been demonstrated. 
In E. solidaginoides the branches of the inflorescence present a 
somewhat racemose appearance, the heads being rather evenly dis- 
tributed along them. In E. flexile this is not the case, the branches 
ing floriferous chiefly toward the tip. In E. solidaginoides the 
heads are 10-15-flowered and the involucre (when fresh or softened 
by boiling) is rather narrowly campanulate, the scales being thin. 
In E. flexile the heads are about 20-flowered, the involucre broadly 
campanulate, and the scales somewhat firmer in texture. The 
achenes of FE. solidaginoides are from 1.8-2.1 mm. long, while in E. 
flexile they are about 2.7 mm. long.

Proc. Am. Acad. liv. 302 (1918). Of this little known Colombian 
Species further material is now at hand extending its recorded dis- 
tribution to the department of Huila, where these specimens were 
collected in forests on the Cordillera Oriental, east of Neiva, Aug. 
1-8, 1917, by Drs. Rusby & Pennell, nos. 573 (N.Y.) and 977 (N.Y.). 
In all characters these correspond closely with a photograph (Gr.) of 
the type (Par.) and of their specific identity there can be no doubt. 
However, the receptacle bears a short, thin and very fugacious pubes- 
cence which commonly disappears so completely with the fall of the
