27. E. ARTicuLATUM Scli. Bip. (see p. 31(5). Merida: in grassy 

 places on the Sierra de Merida, Moritz, nos. 1371 and 1410, ace. to 

 Hieron, 1. c. 385. 



28. E. IBAGUENSE Sch. Bip. (see p. 317). Merida: near Tovar, 

 Fendler, nos. 642 (Gr.), 643 (Gr.). Federal Dist.: Caracas, Moritz, 

 no. 252 (sk. and fragm. Gr.). 



28a. E. n. sp.? At this point in keying the available material 

 of the Venezuelan Eupatoriums is to be placed a doubtfully distinct 

 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 drnng. 

 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.
