Common on sand ridges along the lake shore.’ (B. P.) 
“Erect shrub, with reddish-brown, mostly smooth branches; branch- 
lets and inflorescence, pubescent to wooly; petioles 6 to 25 mm. 
long; leaves from lanceolate to ovate, acute or short acuminate, 
acute or obtuse at base, appressed-pubescent to glabrate above, 
white beneath and with wooly hairs variously intermingled with 
appressed ones (or in some cases all appressed), 2.5 to 12 cm. 
long, 1.2 to 7.5 cm. wide; flowers in small rather compact cymes; 
calyx teeth from small to prominent; fruit white; stone decidedly 
compressed, flat-topped, rarely oblique, with a very prominently 
furrowed edge, much broader than high (3 mm. high, 4 to 6 mm. 
broad). 
It differs from C. asperifolia in its mostly glabrate upper leaf surface, 
white lower leaf surface, and much compressed deeply furrowed 
stone, which is much broader than high. It differs from C. stoloni- 
fera , with which it has been mostly confused in herbaria, not only 
in the woolliness of the lower leaf surface, but very strikingly in 
the stone characters just enumerated. It resembles 0. serieea so 
little that a statement of the differences would be a repitition of 
all the specific characters.” Coulter & Evans , Botanical Gazette

Prof. E. J. Hill, in honor of whom the species is named, furnishes 
us with the following description : 
General appearance much like that of C. pumilus, Torr., but the 
whole plant is smaller and more simple in habit, 15 to 20 inches 
high; heads large, rarely more than one, naked or with 1 to 3 
narrow involucrate leaves; root perpendicular, simple, very slender 
for 2 to 6 inches below the crown, then enlarging, hollow and 
fusiform, about 8 to 10 inches long; leaves smaller and less divided 
than in C. pumilus, often, especially the younger ones, nearly 
undulate ; scales of the involucre with a dark glutinous line on the
