E. epilobioides HBK. but differing from all these in its more cordate 

 leaves and particularly in the presence of numerous tack-like glands 

 on the inflorescence, the plant lieing otherwise entirely glabrous.

 (type Gr.). 



A species at first sight suggesting a possible small-headed form of 

 E. chrysosfictum, but clearly distinct through a variety of characters not 

 likely to be intergradient, as, for instance, the impunctate leaves with 

 pellucid veins, the much more extensive branching (attaining to the 

 third and fourth order) of the panicle, etc.
