A very extreme variant of the common little Erigeron hyssopifolius 
of slaty and calcareous gravels and damp ledges in the Canadian and 
Hudsonian districts. Ordinarily (and in Michaux's type material) 
the taller branching and densely tufted stems and the pedicels are 
glabrous or only sparingly pilose and the otherwise glabrous leaves are 
at most sparingly short-ciliolate on the margin and midrib.

longis cum glandulis stipitatis minutis mixtis; foliis imis lanceolatis vel 
oblanceolatis 3-15 em. longis 5-12 mm. latis acutiusculis apice calloso 
mutico basi in petiolos marginatos angustatis utrinque glandulosis laxe 
villosisque pilis 1-1.5 mm. longis, margine integris vel remote calloso- 
dentatis; foliis caulinis 1-2 jugis, inferioribus lanceolatis 2-4.5 cm. 
longis glandulosis villosisque apice calloso mutico, superioribus multo 
minoribus linearibus vel lanceolatis 1-3 em. longis apice saepe lineari- 
attenuato scarioso; capite 1 pulchro 4.5 cm. diametro: involucro 
circa 1.5 cm. alto basi dense villoso supra glanduloso laxe villosoque; 
bracteis 8-10, anguste rhomboideis 3-3.5 mm. latis a medio ad apicem 
longe attenuatum tenuem angustatis; ligulis circa 10 luteis, lamina

argute 3-4-dentata, dentibus longioribus 3-5 mm. longis; achaeniis 
6-7 mm. longis hirsutis; pappo circa 7 mm. longo albo, setibus barbel- 
latis. 
Rhizome 2-4 em. long, horizontal or suberect: stem solitary, 1-1.8 
dm. high, villous especially above; the white hairs up to 2 mm. long, 
mixed with minute stipitate glands: basal leaves lanceolate or ob- 
lanceolate, 3-15 cm. long, 5-12 mm. wide, acutish with a blunt callous 
tip, narrowed to margined petioles, glandular and loosely villous on 
both surfaces (the hairs 1-1.5 mm. long), margin entire or remotely 
callous-dentate: cauline leaves 1 or 2 pairs; the lower lanceolate, 
24.5 em. long, glandular and villous, with a blunt callous tip; the 
upper much reduced, linear or lanceolate, 1-3 em. long, often with a 
linear-attenuate scarious appendage at tip: heads solitary, very 
handsome, 4.5 cm. broad; involucre about 1.5 cm. high, densely 
villous at base, glandular and loosely villous above; bracts 8-10, 
narrowly rhombic, 3-3.5 mm. broad, tapering from the middle to a 
long-attenuate thin tip: rays about 10, orange-yellow; the oblong- 
ovate blade 1.3-1.5 em. long, 7-8 mm. broad, conspicuously 7-9- 
nerved, strigose on the back, the apex sharply 3-4-toothed, the longest 
teeth 3-5 mm. long: achenes 6-7 mm. long, hirsute: pappus about
