Phyllotheca parvifolia Nutt.; Moq. in DC. Prodr. 132: 98, as synonym. 1849. 
Perennial from a fleshy fusiform root, much branched, the branches slender, prostrate or 
sometimes ascending, 1.5-5 dm. long, terete, furfuraceous-canescent ; leaves numerous, often 
crowded, alternate, or the lower opposite, the blades elliptic to lanceolate or oblanceolate, 
0.6-2 cm. long, 5 mm. wide or less, acute at each end, sessile, entire, furfuraceous-canescent ; 
flowers monoecious, in dense axillary clusters, forming stout, dense, leafy or nearly naked 
spikes; calyx deeply 4-cleft; fruiting bracts sessile, ovate or broadly ovate, 3 mm. long, free, 
thin, acute, entire, green; seed 1 mm. long, black, the radicle lateral. 
TYPE Locality: California. 
DIsTRIBUTION: Seacoast, from San Francisco, California, southward to Lower California, 
and on the adjacent islands. 
VI. Graciliflorae. Erect annuals, loosely farinose or glabrate. Leaves alternate, short- 
petiolate, the blades broad, often subcordate at the base, entire. Flowers monoecious, the 
staminate glomerules paniculate. Fruiting bracts pedicellate, suborbicular, very large, united, 
entire or nearly so. Radicle superior.

II. 5: 717. 1895. 
Erect annual, 1.5-3 dm. high, much branched, the branches stout or slender, ascending 
or decumbent, terete, whitish, sparsely farinose when young, glabrate in age; leaves numerous, 
alternate, the petioles 2-4 mm. long, the blades rounded-deltoid, suborbicular, or ovate-orbicu- 
lar, or the uppermost oblong-ovate, 8-20 mm. long, rounded to acutish at the apex, truncate or 
subcordate at the base, entire, rather thin, loosely farinose when young, glabrate in age; flowers 
monoecious, the staminate glomerules in loose naked terminal panicles, the pistillate flowers 
solitary or fascicled in the axils; calyx 5-cleft, farinose; fruiting bracts on slender pedicels 
2-6 mm. long, suborbicular, 10-16 mm. long, united, the green margins 2-4 times as wide as 
the body of the fruit, entire or undulate, sparsely farinose; seed 3 mm. long, the radicle superior. 
TYPE LOCALITY: Blue Valley, near the Henry Mountains, Utah. 
DistTRiBvurIoNn: In alkaline soil, vicinity of the type locality. 
VII. Saccariae. Erect annuals, densely farinose. Leaves alternate, petiolate, the blades 
mostly cordate-ovate, entire. Flowers monoecious, the staminate usually in short terminal 
spikes. Fruiting bracts of 2 kinds, some large, pedicellate, and densely muricate, the others 
small, cuneate, unappendaged. Radicle superior.

Atriplex expansa cornuta M. E. Jones, Contr. West. Bot. 11: 21. 1903. 
Erect annual, 1-3 dm. high, densely farinose throughout, much branched, the branches 
slender, terete, ascending or spreading; leaves numerous, alternate, the petioles 2-5 mm. 
long, the uppermost leaves subsessile; leaf-blades broadly cordate-ovate, subreniform, or 
rounded-deltoid, rarely subhastate, 0.8-2.5 cm. long, rounded to acutish at the apex, rounded, 
truncate, or cordate at the base, entire, thin; flowers monoecious, the staminate glomerules 
in the upper axils or in short naked terminal spikes, the pistillate flowers mostly in fascicles 
of 1-3 in the lower axils; calyx 5-cleft; fruiting bracts of 2 kinds, the larger ones on pedicels 
4-6 mm. long, united at the base, rounded-triangular or suborbicular, 4-6 mm. long, irregu- 
larly and coarsely dentate, the sides very irregularly and densely crested and dentate over the 
whole surface, the smaller fruiting bracts in the same axils as the large ones, oblong or cuneate, 
3 mm. long, truncate or emarginate at the apex, usually not appendaged on the sides; seed 
brown, 1.5-2.2 mm. long, the radicle superior. 
Type LOCALITY: On the desert plains of southern Wyoming or northern Utah, 
DISTRIBUTION: Dry plains and hillsides, southwestern Wyoming and eastern Utah to north- 
eastern Arizona and northwestern New Mexico.
