6. Douglasia johnstoni A. Nelson, l. c., p. 37. 
A depressed perennial, the eaudex with few, slender, naked branches 
not rising above the soil, each branch terminating in a close rosulate 
cluster of leaves less than 1 em high and broad: leaves minute, 3—6 mm 
long, closely imbricated, glabrous except for a sparse marginal fringe of 
white ciliae, mostly oblong, subacute, somewhat keeled: peduncles rising 
singly from the center of each rosula, sparsely ciliate-hirsute as is also 
the inflorescence: 8—10 mm long: umbel crowded, few-flowered (3— 8): 
bracts lance-linear, as long as the pedicel and calyx: pedicels nearly 
equal, very short: calyx campanulate, its lobes lanceolate, subacute, as 
long as the tube: corolla-lobes oblong obovate, as long as the tube, 
reflexed and withering-persistent over the distended tube: stamens inserted 
just above the middle of the tube, the large anthers extending to the 
narrowed orifice of the throat: capsule sessile, globose. 
This well marked species I believe is the first Douglasia reported 
from Colorado. It was secured by Mr. Earl Lynd Johnston, August 
16, 1906, near the foot of Mt. Washington, on the trail to Chasm Lake, 
Long's Peak. 
7. Coleosanthus garrettii A. Nelson, l. c., p. 38. 
Apparently tufted, with several assurgent herbaceous stems, leafy, 
bright green and glabrous (a minute puberulence under a good lens): 
leaves very thin, from very broadly to narrowly triangular-ovate, mostly 
irregularly and sharply dentate, acute at apex, the base cuneate, rounded, 
truncate or subcordate on the stame stem, 4—8 cm long, on slender 
petioles 1,5—3 cm long: heads on slender ascending branchlets from the 
uppermost axils, few-several in each cluster, on slender pedicels $—15 mm 
long: involucres campanulate, 10—14 mm high, subtended by a few 
linear or acuminate bractlets; the braets in 3—4 series, greenish, with 
about 5 pale nerves, scarious-margined, obtuse or abruptly acute, nearly 
glabrous: achenes brown, glabrous or nearly so, finely ribbed. 
From City Creek Canon, Salt Lake County, Utah, August 5, 1904.

8. Machaeranthera latifolia ^. Nelson, l. c., p. 38. 
Perennial from woody roots and short branched caudex: stems few- 
several, slender, erect, 1,5—2,5 dm high, minutely puberulent: leaves 
minutely puberulent (the upper face nearly glabrous), mostly entire, 
rarely with a few small spinulose teeth, generally 3-veined from the base 
and somewhat reticulate above: the basal and lower stem leaves from 
broadly oblanceolate to obovate, 2—3 cm long, tapering into a short, 
narrowly margined petiole; the upper stem leaves sessile or nearly so, 
those of the inflorescence reduced and becoming bract-like: heads few, 
corymbose, relatively large, 8—14 mm high: involucre campanulate, its 
bracts in 5—6 series, oblanceolate or oblong-lanceolate, the dark-green 
acute or acuminate tips ultimately reflexed, minutely glandular puberulent 
(the peduncles puberulent but scarcely glandular): rays blue with a
