 Ecuador: vicinity of Canar, 15-16 Sept., 1918, J. N. & G. Rose, 

 no. 22,766 (Gr., U. S., N. Y.). Clearly of the affinity of E. gracile 

 HBK., E. prundlacfolium HBK. etc., but characterized by leaves 

 which are broader than long and rather deeply cordate.

 Robinson, Proc. Am. Acad. liv. 285, 338 (1918), where vars. mllosum 

 Steetz, glabrescens Steetz, and breviflorum Hieron. are distinguished. 

 Of this always characteristic yet somewhat polymorphous species it 

 is now possible to add another variety as follows : 



Var. adenotrichum, var. nov., habitu foliisque fere ut apud var. 

 a viUosuni differt tamen ramulis pedicellisque inflorescentiae glandu- 

 lari-puberulis; capituhs paullo minoribus ca. 5.3 mm. longis; in- 

 volucri squamis numerosioribus ca. 22 omnibus peracutis vel attenu- 

 atis. — Colombia: in a ravine, alt. 700-1500 m., Cordillera Oriental, 

 east of Neiva, Dept. Huila, Rushy & PcnncU, no. 480 (N. Y., Gr.). 



It is, of course, impossible to say whether the glandular indumentum 

 will prove to be regularly correlated with the slightly smaller heads 

 and more numerous and sharper-pointed scales or whether these 

 features will be found to have independent variability. However, 

 the combination present in the material at hand seems to warrant 

 varietal rather than formal distinction.
