Zygadenus salinus, n. sp. — Bulbs globose, or even depressed 

 globose, not deep-set (4-8 cm.), 1-3 cm. in diameter; outer bulb- 

 coats brown, thin, and fragile; the next succeeding ones delicately 

 thin-scarious, glistening white : leaves green, grasslike, usually 

 folded, scabrous on the margins, somewhat pruinose, especially 

 on the greenish sheaths, 7-12 mm. broad, shorter than the scapose 

 stems: stems slender, erect, 3-6 dm. high, with 2-3 non-sheathing 

 linear leaves: raceme short, rather crowded; the pedicels slender, 

 becoming 2-3 cm. long; the bracts with short ovate base and very 

 long linear acumination, the lower as long as or longer than the 

 pedicels: flowers in a simple raceme, yellowish- white ; perianth 

 segments nearly similar, 3-7-nerved, all clawed; the sepals with 

 very short claw, ovate, obtuse; the petals elliptic, obtuse, with 

 evident claw which is more or less concave or inrolled; the glands 

 in both small, inconspicuous, and confined almost wholly to the 

 upper part of the claw: stamens surpassing the perianth, on fila- 

 ments only slightly dilated below: ovary free from the calyx; 

 the styles 2-3 mm. long: fruit ovate, about 6 mm. long; the cells 

 united to the summit. 



I should hesitate to describe this as a new species were it not for the glo- 

 bose bulbs and the habitat. The near allies are Z. venenosus Wats, and Z. 

 intermedins Rydb. These have elongated bulbs; the former has conspicuous 

 glands, and the latter has all the leaves with scarious sheathing base. Both 

 have deep-set bulbs, and belong to dry non-saline soil, while the proposed 

 species was secured in alkali-bog lands, with the bulb but a few centimeters 

 below the surface. It seems that typical Z. venenosus is confined to the coast 



Wash. 108, and Blankinship, Mont

Salix boiseana, n. sp. — A low shrub, forming clumps, 1-2 m. 

 high: twigs glabrous, reddish brown or chestnut, slightly shining 

 or obscurely glaucous: leaves oblong, either obtuse or subacute at 

 apex, usually cuneately narrowed at base, 2-4 cm. long, minutely 

 pubescent but green above, pale with a fine tomentum beneath, 

 margin quite entire; stipules wanting: pistillate aments with two 

 or three foliar bracts at base, 3-5 cm. long: floral bracts (scales) 

 small, ovate, obtuse and brown, about half as long as the pedicels, 

 long silky hairy below, especially near the apex and margin, gla-
