NEW OR NOTEWORTHY SPECIES. 157 
twice as numerous as in E. glaucus, broader and of a deep 
blue. 
Shady slopes at 9,500 feet in the mountains towards 
Pagosa Peak, southern Colorado, 23 Aug., 1899, C. F. Baker. 
Much more showy than any forms of its ally, E. glaucus. 
v TowNsgNDIA BAKERI. Subacaulescent and depressed 
perennial: somewhat rosulate leaves oblanceolate, spatu- 
lately tapering to a long and narrow petiole, the whole 1 to 
nearly 2 inches long, the petiolar part, and also the naked 
and scapiform peduncles, canescent with a villous pubes- 
cence, the leaf proper glabrate, of membranaceous texture: 
peduncles barely an inch long; heads rather large, the 
involucre hemispherical, the oblong or elliptic-oblong acute 
bracts imbricated in about 3 series, deep green, but with a 
narrow and closely ciliolate scarious margin: rays white, 
but externally green, or greenish with a purple tinge: disk- 
corollas of a vivid green: pappus of the disk plurisetose, of 
the ray very short, not longer than the breadth of the 
. achene, but setulose rather than squamellate. 
On dry hills among pines, at Los Pinos, Colorado, 16 May, 
1899, C. F. Baker. This appears to be a short-lived peren- 
nial, most of the specimens being small, with a tuft of leaves 
and peduncles from the simple crown of a perpendicular 
root. These I infer to be young plants of one or two years 
from the seed. Others are much larger and truly multicip- 
itoua, the short branches of a former season having survived 
and put forth each its tuft of leaves and flowers. These 
must be older specimens, and have the habit of other mul- 
ticipitous species. 
MACHJERANTHERA PRUINOSA. Root not known, the stout 
widely and subcorymbosely panicled stem 3 feet high or 
more, purple, but whitened with a pruinose pubescence of 
stiff, many-jointed hairs, but in no degree viscid or glan- 
dular: leaves (only the upper cauline known) oblong-lance-
