3. A. coulteri Dictr. Erect or diffusely branching annual, 3-10 

 dm. high, woody at base, the branches very slender; leaves oblance- 

 olatc or lanceolate, 12-25 mm. long, entire, sessile or the lower peti- 

 oled; fruiting bracts rounded, 2 mm. broad, with a narrow herbaceous 

 laciniately toothed border reaching nearly to the base, reticulate- 

 veiny on the sides and smooth or rarely muricate.

4. A. expansa Wats. Annual, erect, much branched, 5-10 dm. 

 high, closely and finely mealy-scurfy; leaves 2.5-7 cm. long, broadly 

 ovate or deltoid-ovate, irregularly and sharply sinuate-toothed, the 

 lower on stout petioles about 1 cm. long, and strongly 3-nerved from 

 the base, the upper reduced to sessile more or less cordate floral 

 bracts, as broad or broader than long; flower clusters more or less 

 unisexual, those of the lower clusters mostly staminate; fruiting 

 bracts sessile, clustered in the axils of the leaves, orbicular, mostly 

 3-nerved, 4 mm. long, 5-6 mm. broad, usually emarginate at the 

 apex, the wing sharply toothed and commonly bearing on one face 

 a few irregular projections or crests. 



Occasional in the Ballona Marshes.

6. A. serenana A. Nelson. Stems rather stout and more or 

 less diffuse, 3 dm. or more long; branches smooth and shining, straw- 

 colored; foliage finely grayish-scurfy; leaves oblong-ovate, acute, 

 8-18 mm. long, thin, sharply toothed or the smaller entire; flower- 

 clusters unisexual, the staminate in terminal simple or compound 

 spikes, the pistillate axillary; fruiting bracts 2 mm. long, the mar- 

 gins laciniately toothed or dentate, the central tooth lanceolate and 

 conspicuous. {A. hracteosa Wats.) 



Very common throughout our range in saline places. 



7. A. califomica Moq. Finely white-mealy; stems slender, leafy, 

 mostly herbaceous, prostrate or scrambling among low shrubs, 

 usually much branched and forming a mat; leaves ovate-lanceolate 

 to oblong-lanceolate, 4-12 mm. long, sessile or narrowed to a short 

 petiole; staminate flowers in terminal spikes, the pistillate in axillary 

 clusters; fruiting bracts membranous, ovate, acute, entire, loosely 

 closed over the utricle but not united, 3 mm. long or less.
