Perennial herbs with scape-like sparingly branched stems from 

 coated bulbs, rather numerous all radical flat narrow leaves and 

 numerous small whitish flowers in somewhat panicled bracted 

 racemes on jointed pedicels. Perianth lax, becoming somewhat 

 scarious but persistent, of 6 distinct oblong closely 3-nerved seg- 

 ments. Stamens 6 adnate to the base of the segments: anthers 

 linear-oblong, versatile. Ovary ovoid, very shortly stipitate : the 

 cells 2-ovuled. Style short, persistent. Seeds oblong, with black 

 shining testa. 



H. alba Watson 1. c. 242. Bulbs membranously coated, or the outer 

 somephat fibious : stem often stout, erect, 1-2)^ feet high : leaves 12-18 

 inches long, 2-6 lines wide, attenuate obove: raceme simple or sparingly 

 branched, densely many-flowered: bracts narrowly acuminate, pedicels 

 1-2 lines long, shorter than the bracts : segments of the perianth about 2> 

 lines long, oblong, obtuse, white or tinged with green or pink, prominently 

 3-nerved: stamens about equalling the perianth: capsule broadly ovoid, 3 

 lines high, very shortly stipitate: seeds oblong, 2 lines long. On dry hill- 

 sides, southern Oregon to California. 



H, bracteosa Watson 1. c. xx, 377. Bulb narrowly oblong, membran- 

 ously coated: stem 1-3 feet high, often stout: leaves 12-20 inches long, 1-4 

 lines wide, acuminate above: racemes simple or sparingly branched, 

 loosely many-flowered : bracts filiform-subulate from a broad base, 6-10 

 lines long or more : pedicels ascending, about 2 lines long: segments of 

 the perianth dull white, lanceolate, acuminate, 4-5 lines long, prominently 

 nerved: stamens about half as long as the segments: mature fruit not

7 CHLOROGALUM Kunth Enum. iv, 683. 



Coarse herbs with fibrous or membranous coated bulbs, narrow 

 radical leaves, scape-like stems paniculately branched above and 

 small scarious-bracted flowers on jointed pedicels. Perianth white 

 or pinkish, of 6 distinct oblong or narrowly ligulate more or less 

 spreading segments with 3 close but distinct nerves down the 

 middle, at length twisted over the ovary and persistent. Sta- 

 mens 6, a little shorter than the segments, inserted on and adnate 

 to their bases: anthers versatile. Ovary sessile or nearly so, with 

 a pair of ascending ovules in each cell. Style filiform, slightly 

 3-cleft at the apex, deciduous. Capsule thick-membranaceous, 

 broadly turbinate, 3-lobed, loculicidally dehiscent. Seeds 1 or 2
