(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 videtur herbacea erecta robusta; 
caule tereti medulloso glabro purpurascenti-brunneo exalato levissime 
striatulo usque 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 em. longo late alato (2 em. latitudine) basi auricu- 
ato-amplexicauli, lobis folii inaequalibus ovato-oblongis plus minusve 
faleatis 3-5 em. longis 3 em. 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; 
capitulis (fructigeris) contiguis ovoideis ca. 8 mm. diametro 1 em. altis 
ca. 25-floris ut videtur discoideis; involucri squamis extimis linearibus 
inaequalibus dorso sordide pubescentibus acutiusculis, intimis spatu- 
lato-oblongis carinatis mucronulatis in media parte subherbaceis 
pubescentibus margine utroque tenuioribus subchartaceis; paleis 
similibus; disco conico; achaeniis nigris 3.2 mm. longis bialatis in 
faciebus pallide tuberculatis, alis albidis ciliolatis; aristis 2 erectis 
1.5 mm. longis tenuibus barbellatis— GuaTEMALA: Quezaltenango, 
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 diff infl d lobed leaves. 
Liabum sublobatum, spec. nov., caule tereti (exsiccatione) striato-
