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 being otherwise entirely glabrous.

A species at first sight suggesting a possible small-headed form of 
E. chrysostictum, 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.
