NEW SOUTHWESTERN PLANTS. 147 
in 2 or 3 series, not very unequal, lance-linear, acute, loosely 
erect, the herbaceous tips purple-edged: rays many, light rose- 
purple. 
In large tufts on stony slopes, Crested Butte, southern Col- 
orado, 13 August, 1901, C. F. Baker, n. 805. A peculiar species 
the near affinities of which it is not easy to name. 
ASTER GRISEUS. Stems decumbent or ascending, 4 to 14 feet 
high, branching, sparingly villous-hairy; foliage and bracts 
pale as if glaucous, but finely strigose-pubescent ; lowest leaves 
oblanceolate, 2 inches long, the cauline oblong-linear to linear, 
all obtuse, entire, 1-nerved, ciliate or ciliolate: heads of middle 
size; involucres broadly campanulate or nearly hemispherical, 
the bracts imbricated in 3 series, erect, appressed even to the 
tips, the outer obovate, obtuse, the inner more elongated, 
acutish, all pubescent and more or less ciliate: rays many, 
showy, pale violet. 
The type is a plant collected by myself thirty years since in 
the Colorado Rocky Mountains west of Denver,on Bear Creek, 
at Sisty’s, the elevation perhaps 9,000 feet. Mr. C. F. Baker’s 
632 from Doyle’s southern Colorado, I think the same, though 
the plants are larger and with herbage even more decidedly 
gray-green. 
BRACHYACTIS HYBRIDA. A foot high or more, branched 
from the base and bushy, the root not always annual, the plant 
apt to propagate by stolons from the crown; stem and branches 
pubescent in lines; leaves spatulate-lanceolate, sessile, entire, 
scabrous-ciliolate, otherwise glabrous ; involucres campanulate , 
bracts in about 2 series and equal, all elliptic-lanceolate, the 
inner narrower, the outer somewhat serrulate-ciliolate; rays 
lavender, elongated. 
Common in alkaline soil about Gunnison, Colo., 27 Aug., 
1901, ©. F. Baker, n. 937. The plant is remarkable as a Bra- 
chyactis for its many long rays, as well as by its apparently per- 
ennial duration; otherwise it is at perfect agreement with other 
members of this well marked genus. The name /yérida is next 
to meaningless here, and I regret having assigned it, as I did, 
in the distribution of Mr. Baker’s collection.
