28a. E. n. sp.? At this point in keying the available material 
of the Venezuelan Eupatoriums is to be placed a doubtfully distinet 
plant represented from Tovar by Fendler’s nos 649 and 650, both 
being in the Gray Herbarium. In nearly all technical characters 
close to the preceding, this plant differs in being smoother. The whole 
plant, in the two specimens seen, is strongly nigrescent in drying. 
The stem, with arched-ascending opposite branches, becomes smooth 
and strongly lignified toward the base. Although the plant is proba- 
bly undescribed, it seems best pending further knowledge of its near 
reatives to leave it unnamed, especially as the material is too young 
to show the flowers in full anthesis. she
