TROPICAL AMERICAN COMPOSITAE. 39 



with markedly different pubescence but otherwise of close similarity 

 can be distinguished, namely: 



Var. a. typicum, caulibus et ramis et petiolis dense patenterque 

 ^^llosis; pilis longis tenuibus flexuosis articulatis. — Peru: A\'ithout 

 locality, Haenke (DC, phot. Gr.); on calcareous rock, near Lima, alt. 

 300-600 m., Wcherhauer, no. 1650 (Berl., fragm. Gr.). 



Var. jS. brevipilum, ^■a^. nov., puberulum vel tomentellum; pilis 

 plerisque brevibus inarticulatis paucis passim longioribus. — Peru : on 

 the Lima-Oroya Railroad, between ]Matucana and Tambo de Viso, on 

 rocks, alt. 2370-2650 m., 26 Dec. 1901, Wehcrbauer, no. 103 (type, Berl., 

 fragm. Gr.); on slopes of eruptive rock, ]Matucana, alt. 2370 m., 24 

 Dec. 1901, Weherhauer, no. 66 (Berl.). 



E. Vargasianuim DC. Prod. v. 155 (1836). Further study of this 

 species leads to the belief that it has been misinterpreted and that to it 

 should be referred E. macrophylloides Robinson, Proc. Am. Acad. liv. 

 249, 340 (1918). The only two collections of the species known to the 

 WTiter are as follows: at Caracas, Vargas (DC, phot. Gr.), and at 

 Sanchorquiz, Eggers, no. 13,413 (U. S.). The localities, both in the 

 Federal District of Venezuela, are not far apart. 



The species has been reported twice from Colombia, namely by Klatt 

 in Engl. Bot. Jahrb. Aiii. 36 (1887), on the basis of Lehmann's no. 938 

 from near Popayan, and by Heering, Mem. Soc. Neuchat Sci. Nat. v. 

 420 (1913), on Mayor's no. 392, from near Medellin. The writer has 

 seen neither of these specimens and cannot confirm the accuracy of 

 their determination, indeed is inclined to question it. 



A related plant, confused with E. J^argasiaimm by Klatt in herb, 

 and by the writer, 11. cc, appears to be a new species and is described 

 above as E. Steetzii. The confusion of these two plants and the acci- 

 dental omission of one species from the author's key to § Subimbricata 

 of the Venezuelan Eupatoriums, Proc. Am. Acad. liv. 337 (1918), 

 necessitates a rcA-ision of the last few lines of the key, thus: 



i. Shrubs; leaves (5-) 6-13 cm. wide j. 

 j. Heads in thyrsoid panicles; scales rounded or obtuse; 



stem glabrate 19. E. morijolium. 



j. Heads in corymbosely branched flattish-topped panicles ; 

 scales acute; stem tomentose k. 

 k. Leaves about two-thirds as wide as long; petioles 1.2- 

 3.8 cm. long; heads 15-18-fiowered; achenes cov- 

 ered with sessile globules 20. E. Steetzii 



k. Leaves about four-fifths as wide as long; petioles 4-6 

 cm. long; heads 10-11-flowered; achenes hispid- 

 puberulent 21. E. Vargasianum.
