 lines long, the petiole i/> to as long; flowers green or reddish, in many small 

 axillary clusters; sepals in staminate tlower 3 (or 2), membranous, oblong- 

 ovate, mucronate or erosulate ; stamens 3 (or 2 or 1): sepals in pistillate 

 flower 1 (or 2 or 3) ; utricle smooth, bursting irregularly and releasing a red

A. albomarmnatus Uline & Bray, Bot. Gaz. 19: 318 (1894), type loc. Monterey (Jo., Palmer 

 456 in 1876. Stems white; leaves elliptical, very small (1 to 2 lines long), conspicuously white- 

 margined; flowers crowded in the dense foliage; sepals 2 or 3, minute, scale-like. — Not known 

 to us, but apparently the plant we here take to be A. californicus. 



7. A. fimbriatus \Yats. Stems several from the base, 1 to 2 feet high, 

 simple or sparingly branched ; herbage glabrous, purplish, especially the 

 inflorescence; leaves linear, narrowed below into a short petiole, 1 to 2 inches 

 long; flowers in rather loose clusters; clusters scattered or mostly approxi- 

 mate and forming a long terminal spike ; bracts ovate, acute, scarious-bordered, 

 shorter than the calyx ; sepals of staminate flowers oblong, obtuse, those of 

 the pistillate flowers broaclly fan-shaped with a narrow thickened base and 

 fimbriate margin, 1 line long; "stamens 2 or 3"; stigmas 3. 



Mohave and Colorado deserts, east to Utah and Texas, south into Mexico.

8. A. palmeri Wats. Stems stout, erect, 2 to 4 feet high, glabrous or 

 pubescent; leaves broadly ovate, acute or acuminate, broadly cuneate at base, 



1 to 4 inches long, on petioles 1 to 2 times as long; flowers dioecious, in dense 

 elongated spikes leafy at base ; bracts solitary, those of the pistillate spikes 

 subulate, spreading, rigid, awn-tipped, narrowly searious-margined at base, 



2 to 3 times as long as the flowers; calyx % to IVo lines long, falling with 

 the fruit, unequal, obscurely cordate at base; sepals of staminate flower 

 oblong-ovate and acute, or oblong-lanceolate and acuminate; sepals of pistil- 

 late flower obovate, refuse or truncate, usuall.y mucronate or setaceously 

 apiculate ; stigmas 2 ; utricle rugose at summit. 



Colorado Desert; east to Texas and south into Mexico. 



Locs. — Holtville, Parish 8269 ; Chemehuevis Valley, Colorado River, Jepson 5209 ; Ft. Yuma, 

 Brandegee : Salton Creek, Brandegee ; Cameron Lake, Brandegee. Abundant in southern 

 Arizona where, cut and stacked by the Mexican population as a winter feed for horses, it 

 yields nearly 3 tons per acre (Bur. PI. Ind. Bull. 67: 58).

9. A. deflexus L. Stems slender, prostrate, a little succulent, 1 to 1% 

 feet long ; leaves rhombic-ovate ; flowers pol.ygamous, in short spikes clustered 

 in the axils, or disposed in dense terminal spikes 1 inch long or more ; sepals

 sepals, indehiscent. 



Introduced from southern Europe; naturalized along streets and in gar- 

 dens ; towns about San Francisco Bay.
