1. Stellaria umbellata Turcz. Bull. Soc. Nat. Mosc. 89. 1838. Glabrous: 

 stems slender, weak, ascending from a decumbent rooting base: leaves from 

 elliptic-oblong to lance-linear: flowers in a simple or compound subumbellate 

 cyme; the pedicels filiform-elongated; the bractlets mmute and scarious: 

 sepals small, 2-3 mm. long, glabrous: petals wanting: capsule twice as long as 

 the sepals. (^Alsine baicalensis Coville, Contrib. U. S. Nat. Herb. 4: 70. 1893.) 

 — From New Mexico to Montana and west to California. 



2. Stellaria longifolia Muhl. Willd. Enum. 479. 1809. Stems sharply 

 4-angled, 1-2 dm. high, mostly slender and weak: leaves linear or broader, 

 narrowed to both ends, 2-4 cm. long: cyme open, many-flowered; the pedicels 

 filiform, widely divergent or deflexed; the bractlets minute and scarious: 

 petals and capsule longer than the calyx. — Throughout our range, and across 

 the continent to the northward. 



3. Stellaria longipes Goldie, Edinb. Phil. Journ. 6: 327. 1822. Shining 

 or somewhat glaucous, very smooth: leaves ascending, lanceolate or linear- 

 lanceolate, broadest at the base: cyme terminal, few-flowered; the long 

 unequal pedicels erect. — Colorado and northward, thence across* the con- 

 tinent. 



3a. Stellaria longipes laeta Wats. Smaller, only 5-12 cm. high, usually very 

 glaucous, leafy below, the cyme often reduced to a solitary long-pediceled 

 flower; as in the species the capsule is dark-colored and somewhat acute. — 

 Same range. 



4. Stellaria valida L. N. Good. Bot. Gaz. 33: 69. 1902. Glabrous: stems 

 4-angled, 1-2 dm. high, branched: leaves lanceolate, tapering from the base, 

 1-3 cm. long: cyme compound, its rays and pedicels subequal; the bractlets 

 small and scarious; pedicels rigid, spreading: petals deeply bifid, scarcely 

 longer than the sepals: the dark brown capsule twice as long as the sepals: 

 styles recurved and crested with fine short bristles. — Type locality, Centen- 

 nial Valley, southern Wyoming. 



5. Stellaria borealis Bigel. Fl. Bost. Ed. 2: 182. 1824. Glabrous or pu- 

 bescent, erect or spreading: stems weak, somewhat branched: leaves ob- 

 long to lance-linear, thin, their margins often ciliate: cyme dichotomously 

 compound, with foliose bracts and slender pedicels: petals shorter (or wanting) 

 than the ovate-lanceolate sepals which are much surpassed by the oblong cap- 

 sule: seeds smooth. (AZsine caj^cani/w Rydb. Bull. Torr. Bot. Club 24: 244. 

 1897.) — Frequent in the mountains; from Colorado northward and across the 

 continent. 



6. Stellaria obtusa Engelm. Bot. Gaz. 7: 5. 1882. Glabrous: the short 

 stems prostrate: leaves ovate, acute, 6-8 mm. long: flowers solitary, on short 

 axillary peduncles: petals wanting: capsule obtuse, longer than the obtuse 

 sepals: seeds brown, covered with minute oblong tubercles with fringed edges 

 (visible only under a strong lens). — Infrequent; in the mountains, Colorado, 

 northward and westward. 



7. Stellaria crassifolia Ehrh. Hannov. Mag. 8: 116. 1784. Glabrous: the 

 stems weak, erect or diffuse: leaves slightly fleshy, from linear-lanceolate to 

 oblong: flowers terminal or in the forks of the stem or the axils of the foliar 

 bracts: petals longer than the lance-oblong acute sepals: capsule ovoid, longer 

 than the sepals :_ the seeds rough. — ^Throughout our range and extending to 

 eastern and arctic America. 



8. Stellaria Jamesiana Torr. Ann. Lye. N. Y. 2: 169. 1828. Viscid- 

 pubescent above: stems sharply 4-angled: leaves lanceolate, 5-10 cm. long, at- 

 tenuate, broadest at the sessile base: flowers in a leafy terminal panicle: 

 petals twice as long as the oblong acute sepals: seeds rough. — From New 

 Slexico to Wyoming and westward.
