nearly so, two or three pairs opposite at base, the upper alternate ; the plant 

 loosely scurfy throughout; leaves oblong-lanceolate or ovate, sessile, 

 3 — 5 lines long; flowers from the axils of the leafy stems in clusters of 

 two or three; calyx deeply 4-cleft, stamens 4; fruiting bracts orbicular, 

 compressed, 2 lines long, the margins crenate-dentate. — Near Collins- 

 ville, on the lower Sacramento. May. 



5. A. depressa, Jepson. Diffuse, grayish-scurfy, decussately branched 

 throughout, the branches 1 — 4 in. long: leaves opposite, sessile, broadly 

 ovate, acute, a line or two long; flowers in the axils of the opposite 

 leaves in clusters of four, these and the leaves crowded on the branch- 

 lets, the internodes at time of flowering a line long or less; fruiting 

 bracts ovate hastate, acute, wingless, or the pair of hastate lobes 

 representing the wing. — In low saline spots, at the base of the Pelevo 

 Hills, west of Vanden, Solano Co. Sept. 



6. A. cordnlata, Jepson. Eigid, virgate, 8 — 15 in. high, widely and 

 oppositely branched at the base, alternately and sparingly so above; 

 herbage scurfy throughout; leaves sessile, cordate-ovate, three or some- 

 times four lines long; flower-clusters in all the axils; calyx tomentosely 

 scurfy and deeply 4-cleft; fruiting bracts semi-orbicular, 13^—2 lines 

 broad; much compressed, sessile or shortly stipitate, the margin with 

 acute teeth, the terminal tooth commonly the largest, the sides smooth 

 or with one or two tooth-like projections. — Near Little Oak, Solano Co. 

 August. 



7. A. nodosa, Greene. Stout, branched from the base, 1 ft. high; 

 mealy and apparently scabrous: leaves broadly rhomboid: fruit-clusters 

 borne at the enlarged nodes of the widely and irregularly branching 

 stem: pedicels stout, thickened under the bracts; these united and form- 

 ing an almost globose fruit 2 lines in diameter, 3-lobed at summit, the 

 sides covered with lichenoid spongy projections.— Near Antioch. 



8. A. trinervata, Jepson. Stout, erect, 2—3 ft. high, closely and 

 finely mealy-scurfy: leaves 1—3 in. long, broadly or deltoid-ovate, irregu- 

 larly and sharply sinuate-toothed, the lower on stout petioles 9—10 

 lines long and strongly 3-nerved from the base: the upper reduced to 

 sessile floral bracts as broad or broader than long; fruiting bracts sessile 

 in the axils of the leaves, orbicular, 2 lines long, 2%— 3 broad, usually 

 emarginate, sharply toothed, partly distinct in the wing, and commonly 

 bearing on one face a few irregular projections or crests.— Near the 

 Araquipa Hills, Solano Co. Sept.

9. A. fruticulosa, Jepson. Erect, suffrutescent at base, %— 1 ft. 

 high: herbage gray-scurfy; leaves sessile, lanceolate or narrowly oblong,
