(1820). To the synonymy of this species may be added Erigeron 

 canadensis as cited in J. D. Sm. Enum PI. Guat. iv. 78 (1895), as to 

 no. 6152. 



Verbesina Holwayi, spec, nov., ut videturherbaceaerectarobusta; 

 caiile tereti medulloso glabro purpurascenti-brunneo exalato levissime 

 striatulo usqvie ad inflorescentiam laxe folioso; foliis alternis ovato- 

 deltoideis utroque latere 1-2-lobatis supra rugosis cum venis impressis 

 reticulatis cum pilis brevissimis albidis scaberrimis subtus paullo 

 pallidioribus viridibus molliter tomentellis ad 1.8 dm. longis 1.4 dm. 

 latis, petiolo ad 9 cm. longo late alato (2 cm. latitudine) basi auricu- 

 lato-amplexicauli, lobis folii inaequalibus ovato-oblongis plus minusve 

 falcatis 3-5 cm. longis 3 cm. latis apice rotundatis margine irregulari- 

 ter serrato-dentatis, lobo terminali multo majori subacuminato, costa 

 media subtus prominenti, venis pinnatis in petiolo transversis in 

 lamina prorsus curvatis; foliis superioribus gradatim reductis lanceo- 

 latis, bracteis ultimis spatulatis vel linearibus minimis; panicula 

 ampla 3 dm. diametro plana multicapitulata sordide puberula vel 

 tomentella, ramis et pedicellis (8-14 mm. longis) adscendentibus;

 pubescentibus margine utroque tenuioribus subchartaceis ; paleis

 faciebus pallide tuberculatis, alis albidis ciliolatis; aristis 2 erectis

 alt. 2290 m., January, 1915, Prof. E. W. D. Holway, no. 96 (type, 

 in Gray Herb.). This species is probably referable to § Lipactinia 

 Robinson & Greenman, Proc. Am. Acad. xxiv. 563 (1899), though 

 in the fruiting material at hand it is difficult to be sure of the absence of 

 rays. It would seem to be most naturally placed near V. auriculata 

 DC. Prod. V. 617 (1836) with which it agrees in many points, though 

 it is readily distinguished by its different inflorescence and lobed leaves.
