sursum hispidis basi callosis apice cum disco parvo flavescente pappi- 

 fero coronatis; pappi setis albis roseo-tinctis sursum scabridulis 

 apicem versus pauUulo incrassatis. — Ecuador: vicinity of Las 

 Juntas, J. N. Rose, A. Pachano, & G. Rose, no. 23,179 (Gr., U. S., 

 N. Y.). 



This plant differs from E. pichinchense HBK. in its copiously 

 gland-tipped pubescence, much smaller, fewer-toothed leaves, etc. 

 From E. glanduliferum Hieron. it may be distinguished by having the 

 leaves petiolate and their blades essentially as wide as long. In many 

 respects it corresponds pretty closely with the Colombian E. sotarcnse 

 Hieron., but that species, according to Hieronymus, has leaves glabres- 

 cent or subglabrescent (while they are here densely and permanently 

 pubescent to ^-illous on both surfaces), rounded at the base (while 

 here distinctly cordate), and longer than wide. 



E. RORULEXTUM Robinson, Proc. Am. Acad. liv. 255 (1918). This 

 species, described from young material with the heads merely in bud, 

 has been collected near Laguna de Verjon, Colombia, by Bro. Ariste- 

 Joseph, no. B20 (Gr.). From this material, which, agreeing as to 

 habit and foliage in all details with the original, is decidedly more 

 mature, it is possible to add the following characters to those recorded 

 in the diagnosis: heads at length S-9 mm. high; corolla whitish 5 mm. 

 long, sparsely atomiferous, proper tube 1 mm. long, the throat about 

 3.4 mm. long, the limb about 0.6 mm. long, the teeth deltoid, acutish; 

 mature achenes dark brown, about 3 mm. long. 



E. (§ Cylindrocephala) Roseorum, spec, nov., brevissime griseo- 

 tomentellum; caule tereti usque ad 4 mm. vel ultra diametro pilis

 acuminatis basi subtruncatis lateraliter paullo crenato-serratis 

 vel undulatis vel integris a basi 3-nervatis plerisque ca. 5 cm. 

 longis 3.5 cm. latis membranaceis subconcoloribus vix subtus pallid - 

 ioribus utrinque tomentellis; petiolo gracile flexuoso 10-18 mm. 

 longo; corymbis modice convexis ramos oppositos vel supra alternos 

 terminantibus multicapitulatis densiusculis conjunctim paniculam 

 semiglobosam vel ovoideam foliaceo-bracteatam formantibus; pedi- 

 cellis plerisque ca. 5 mm. longis; capitulis ca. 17-floris 1.5 cm. longis 

 4 mm. latis; involucri cylindrici squamis ca. 30 gradatim regulari- 

 terque imbricatis ciliolatis; extimis brevissime oblongis apice ro- 

 tundatis dorso puberulis et sparsim atomiferis subherbaceis; inter- 

 mediis et intimis gradatim longioribus ciliatis aliter glabriusculis
