EUPATORIUMS OF VENEZUELA. 339 



16. E. viTALBAE DC. (see p. 299). A species of frequent occur- 

 rence and wide distribution in the warmer parts of America, but not 

 yet reported from Venezuela. However, as it is known to occur in 

 Colombia, to the west, Dutch Guiana to the east, and Brazil, to the 

 south, its ultimate discovery in this as yet very slightly explored 

 country, seems highly probable. 



17. E. AMYGDALiNUM Lam. (see p. 301). Venezuela: without 

 locality, Moritz, no. "6(80)" (Gr.). Merida: near Tovar, Fendler, 

 no. 654 (Gr.). Federal Dist. : Galipan near Caracas, Kiintze, 

 no. 1525b (N. Y.). 



A very sketchy subdivision of this species has been attempted by 

 Kuntze, Rev. Gen. i. 337 (1891). Quite without detailed statement 

 of differential characters, ranges, previous literature, or of critically 

 determined exsiccatae the treatment is of little ^-ahle. The subdivi- 

 sions are based on characters which are confessedly subject to inde- 

 pendent variation, their combinations being numerous and inconstant, 

 so that they have almost no classificatory value. Finally to make 

 the matter worse, even the rank of the proposed subcategories is in 

 several cases left wholly obscure. 



18. E. INULAEFOLIUM HBK.,formaTYPicuM (see p. 292). Widely 

 distributed from Colombia to Brazil, and with scarcely a doubt to be 

 found in Venezuela. 



Forma suaveolens (HBK.) Hieron. (see p. 292). Merida: near 

 Tovar, Fendler, no. 641 (Gr.). 



19. E. Vargasianum DC. (see p. 289). Bermudez: Aragua, 

 Cruger (K.) Federal Dist.: Caracas, Vargas (DC, phot. Gr.), 

 Linden, no. 137 (K.). Merida: near Tovar, Fendler, no. 647 (Gr.). 



20. E. MORiFOLiuM Mill, (see p. 293). Merida: near Tovar, 

 Fendler, no. 646 (Gr.). 



To this species may be provisionally referred Critonia heteroneura 

 Ernst, Flora, Ivii. 210 (1874). Federal Dist.: on Mt. Galipan near 

 Caracas, Ernst. No material authentically representing Ernst's 

 species has been seen, yet his description is careful and so detailed 

 that it is possible to check up the many points in which his plant 

 agrees fully with E. morifolmm. It is true the florets are said to be 

 only four, while in E. morifolium they are often considerably more 

 numerous, but the number appears to be quite variable even in speci- 

 mens obviously otherwise identical. The peculiar nervation, on 

 which Ernst laid stress as a dift'erential character and which suggested 

 the name he chose for his plant, can be accurately matched even in 

 specimens from Vera Cruz, the type-region of E. morifolium.
