180 CHENOPODIACEiE. 



high; herbage closely and finely mealy-scurfy; leaves 1 to 3 in. long, 

 broadly ovate or deltoid-ovate, irregularly and sharply sinuate- 

 toothed, the lower on stout petioles 9 or 10 lines long and strongly 

 3-nerved from the base, the upper reduced to sessile and more or less 

 cordate floral bracts as broad or broader than long; flower clusters 

 showing a tendency to become unisexual, the staminate flowers in the 

 lower clusters more or less sterile; fruiting bracts numerous, clustered 

 in the axils of the leaves, sessile, orbicular, mostly 3-nerved, 2 lines 

 long, 2J to 3 lines broad, usually emarginate at apex, the wing sharply 

 toothed, partly distinct, and commonly bearing on one face a few 

 irregular projections or crests. — (A. trinervata Jepson.) 



Low alkaline areas from the base of the Coast Range foothills of 

 northwestern Solano Co. southeastward to the lower San Joaquin, 

 where it is a weed in the grain fields near the river. Eecent speci- 

 mens from Solano Co. seem to indicate that the plants there are more 

 or less dioecious. A. nodosa Greene, Pitt. i. 40, is unmistakably a 

 monstrous form of this species, perhaps due to insect stings. A speci- 

 men from near Stockton, Davy, matches in some of its branches the 

 abnormal branches and inflorescence of A. nodosa; the remaining 

 branches are typical A. expansa! 



8. A. bracteosa Wats. Perennial, more or less difiuse, with 

 stems 1 to several ft. long; branches smooth and shining, straw- 

 yellow; foliage finely grayish-scurfy; leaves oblong-ovate, acute, 4 to 

 9 lines long, thin, sharply but sparingly toothed or the smaller entire; 

 flower clusters unisexual, the staminate in terminal submoniliform 

 spikes, the pistillate axillary; fruiting bracts a line long, the margin 

 laciniately toothed or simply dentate and the central tooth lanceolate 

 and conspicuous. 



Sacramento, Miehener; Andrus Island and Tyler Island, Lower 

 Sacramento, Jepson; Antioch, Mrs. Brandegee; and southeastward 

 through the San Joaquin Valley to Kern Co. , where it is common. 



9. A. fruticulosa Jepson. Perennial; herbaceous or sufi'rutescent 

 below, erect, 6 to 13 in. high, and branched from the base, the stems 

 simple below, with terminal branchlets; herbage grayish; leaves 

 sessile, lanceolate or narrowly oblong, J to f in. long; staminate 

 flowers in dense globose clusters 2 lines in diameter, the clusters in a 

 terminal simple or sometimes slightly branched spike, naked or nearly 

 so; pistillate chiefly below, from the leaf axils; calyx deeply 5-oleft, 

 occasionally unequally parted and one lobe reduced; fruiting bracts 

 orbicular, 1^ to 2 lines broad, the margins partly free, the sides tooth- 

 crested; seed nearly a line broad. 



Leesville, Colusa Co.; alkaline flats near the Little Oak Eanch, 

 Solano Co., Jepson; Antioch, Mrs. Brandegee, June 8, 1892. The 

 name not well chosen, but the first specimens with perennial woody 

 stems 3 to 6 in. high. 



10. A. Californica Moq. Finely white-mealy or somewhat 

 glabrate in age; the hue of the herbage mostly greenish; root large 

 and somewhat fleshy; stems slender, wiry, mostly herbaceous, pros- 

 rate, often much branched and forming a thick mat; leaves thinnish ,
