1905] NELSON—ROCKY MOUNTAIN PLANTS 65 
Crepis alpicola (Rydb.), n. sp.—Caudex short, vertical, semifleshy: 
leaves glabrous, rosulate on the crown, linear-oblong or oblanceolate, 
acute at apex, sessile or tapering into a short margined base, entire 
or saliently toothed or even subruncinate, 3-6°™ long: stems scapose, 
simple, glabrous, with one or two linear bracts, 10-20°™ high, usually 
monocephalous: involucre about 14™™ high, dark green, clammy or 
glandular pubescent; its bracts in 3 or 4 successively shorter rews: 
ligules 2°™ long: akenes short, fusiform, shorter than the fine white 
pappus. 
This is probably C. runcinata alpicola Rydb., Bull. Torr. Bot. Club 24: 299, 
although the above description does not quite tally with the brief diagnosis of 
the variety. A reasonable amount of variation will account for any differences. 
It is to be compared, however, with C. riparia, because of its large heads and the 
gland-tipped pubescence on the involucre. It is distinct from that species in 
its small glabrous leaves, its one-flowered stems, its involucre of 3 or 4 rows of 
bracts, and its short fusiform akenes. Cooper secured it in an alpine meadow 
(11,000%) on Long’s Peak, Aug. 3, 1904, no. 218. 
MISCELLANEOUS SPECIES. 
Gilia exserta, n. sp.—Biennial, 2-34" high: stem single at 
base but branched from near the base upward; branches mostly sim- 
ple and moderately divaricate, almost equaling the main stem, 
minutely pruinose-viscid: leaves 2-5°™ long, somewhat pungent, 
linear, entire or simply pinnatifid, with few to several linear lobes: 
flowers in small bracteate cymes forming narrow panicles: calyx 
membranous, narrowly campanulate, about 4™™ long, merely prui- 
Nose; its teeth very short, green, triangular-subulate, and minutely 
pungent: corolla white, purple dotted, 1o-12™™ long, somewhat 
trumpet-shaped; tube surpassing the calyx; its lobes elliptic-oblong, 
acute, almost as long as the tube: stamens noticeably exserted; 
style scarcely so: ovules about 2 in each cell; seeds destitute of 
mucilage. 
The type is no. 538, by C. F. Baker, Pagosa Springs, Colo., July 28, 1899. 
It was distributed on GREENE’s determination as G. multiflora Nutt., which it 
certainly cannot be. It seems nearer G. stenothyrsa Gray of the section G1xt- 
RA (Syn. Fl). 
~* Amelanchier oreophila, n. sp.—A low scraggy-branched shrub, 
I-2™ high, growing mostly in close clumps: young leaves, petioles, 
and twigs more or less lanate-pubescent, some of the pubescence 
Persisting till maturity, especially on the lower face of the leaves:
