brate above: pedicels slender, 1.5-2 mm. long; capsules glabrous, 

 3-4 mm. long: style evident but very short (less than 0.5 mm.). 



This is most nearly allied to S. Wolfii Bebb, but seems to be distinct by 

 the cuneate base of the leaves, which are glabrous or nearly so above, tomentose 

 on the lower face (not silky-villous with shining hairs on both sides), by the 

 longer pedicels, the slenderly virgate fertile stems (S. Wolfii is freely short- 

 branched), and the longer fertile aments. S. boiseana belongs to lower alti- 

 tudes and matures much earlier in the season. 



Miss June Clark secured the type material (no. 48) in overripe condition, 

 May 29, 191 1, near Boise at an altitude of less than 3000 feet. 



Eriogonum fasciculifolium, n. sp. — The shrubby base low 

 c-2 dm.) and somewhat di- or trichotomously branched; the more 

 or less scaly bark dark brown or dirty black: leaves fasciculate or 

 verticillate on the enlarged nodes, mostly on the crownlike apex 

 of the branchlets, linear or narrowly oblanceolate, 1-3 cm. long, 

 tapering to a short petiole, rather thick, pale-green, glabrate above, 

 obscurely tomentose below: peduncles from the upper nodes or 

 terminal, 4-8 cm. long, bearing a few-rayed umbel, lightly pubes- 

 cent; the bracts foliar, apparently always few (2-4), or sometimes 

 wanting: rays 12-20 mm. long: involucre many-flowered, campanu- 

 late, its ovate-oblong reflexed lobes as long as the tube, sparsely 

 silky-villous: flowers pale yellowish- white, rather large: sepals 

 similar, broadly obovate, about 5 mm. long, lightly silky-villous 

 below and on the pedicel to the joint: filaments pubescent below, 

 much shorter than the triangular glabrous achene. 



This new member of § Pseudo-umbellata is at once distinguished by its 

 branched shrubby base and its very narrow leaves, though it has all of the 

 characteristics of the section. 



A limited quantity only was secured by Miss June Clark at Tamarack, 

 Washington County, Idaho, August 12, 191 1, no. 236, on a dry mountain side. 



Stellaria (Alsine) praecox, n. sp. — A diminutive vernal species 

 of arid districts: stems usually simple but sometimes branched 

 from the base, glabrous except for some crisped hairs on the lower 

 internodes, 7-15 cm. high (including the long filiform pedicels):

filiform stem 



long: cyme unequally 3-rayed, some of the rays again unequally 

 trichotomous; the bracts minute, somewhat scarious: sepals
