 1.6-4 cm. latis; petiolo 1-4 cm. longo subtus convexo subglabro supra 

 canaliculato villoso ; capitulis 9 mm. longis 6 mm. diametro 20-floris 

 numerosis ad apices ramorum glomerato-aggregatis, corymbis rotun- 

 datis densiusculis ca. 4 cm. diametro ; pedicellis filiformibus puberulis 

 2-6 mm. longis ; involucri campanulati squamis ca. 10 elliptico- vel obo- 

 vato-oblongis aequilongis apice rotundatis saepius pulcherrime ciliatis 

 dorso pubescentibus 3.2 mm. longis 1.5 mm. latis pallide viridibus ; 

 corollis albis, tubo proprio gracili 2 mm. longo glabro, faucibus cam- 

 panulatis giabris, dentibus limbi 5 deltoideis pilosiusculis ; antheris 

 vix connatis apice longe appendiculatis ; achaeniis nigrescentibus 5- 

 angulatis 1.5 mm. longis sursum praesertim in angulis hispidulis apice 

 cupula albida coronatis ; pappi setis capillaribus vix barbellatis laete 

 albis vel saepissime pulcherrime roseis corollam fere aequantibus ca- 

 ducis. — Open moist places, rocks of barranca, Ixtaccihuatl, Mexico, alt. 

 2440 m., C. A. Parpus, no. 1496 (type, in hb. Gray) ; also in the Valley 

 of Mexico, Schaffner, no. 201 (hb. Gray). This species differs from E. 

 pazciiarense HBK. in its very obtuse involucral scales ; from E. photinum 

 Robinson, in its thin pubescent less attenuate leaves. It is perhaps 

 most nearly related to E. Schaffneri Gray, but it differs from that 

 species in its more attenuate-acuminate and more regularly serrate 

 leaves which are pinnately veined, while in E. Schaffneri they are 

 palmately nerved from the very base.
