TROPICAL AMERICAN' COMPOSITAE. 19 



1 Mar. 1918, Dr. F. W. PcnncU, no. 4.561 (X. Y., phot, and fragm. 

 Gr.). 



This species with something of the habit of a SoUdago is clearly of 

 the affinity of E. cJatitm Steetz, E. turhaccnse Hieron., E. Squircsii 

 Rusby, and E. tovarcnsc Robinson. From all these it difFers in its 

 much narrower, much more gradually attenuate, and in texture more 

 delicate leaves of somewhat different venation and essentially glabrous 

 beneath. In style-branches and some other features it recalls E. 

 Trkinac Robinson but differs in its opposite leaves, slender-pedicelled 

 heads, etc.

 16-17 Sept. 1918, ./. .V. & G. Rose, no. 22,774 (Gr., U. S., X. Y.). 

 X^ot closely related to any hitherto described Ecuadorian species. 

 The lower surface of the leaves is closely covered with a somewhat 

 lepidote pubescence except the midnerve and chief veins which are 

 essentially bare. In habit and foliage the species recalls several 

 Eupatoriums of Peru and Bolivia, but these are of § Eximhricaia 

 rather than § Subimbricata to which the present fpecies is clearly 

 referable.
