 albis ca. 4 mm. longis. — Ecuador: vicinity of Guayaquil, 30 August 

 to 2 Sept., 1918, ./. .V. & G. Rose, no. 22,4(34 (Gr., U. S., N. Y.). A 

 handsome species with deltoid-ovate leaves recalling those of E. 

 iresinoides HBK. but with involucre characteristic of § Cylindro- 

 cephala. The involucral scales (green, white, and lilac) recall those 

 of E. iridolcpis Robinson. An attractive and seemingly very distinct 

 species which it is a pleasure to dedicate to Dr. J. X. Rose of the 

 United States National Museum and to his son, who was his assistant 

 on a recent collecting trip to Ecuador,

 alt. 2135 m., E. Jcnman, no. 311 (type, U. S.); ledge, Roraima Exp., 

 E. F. Ini Thurn (K., phot. Gr.). These specimens appear absolutely 

 identical, both being tips of branches carrying two or three of the 

 upper leaves and a terminal corymb in bud. In each there has been 

 some damage from insects, especially to the immature achenes. This 

 is certainly the plant mentioned by Daniel Oliver, Trans. Linn. Soc. 

 ser. 2, Bot., ii. 277 (1887), as "No label. Eupatorium, sp.? (not 

 identified)." Although the material is poor, it discloses practically
