 Obione Coulteri, Moquin, 1. c. 113. 



Known only from scanty specimens in the herbarium at Kew, collected by Coulter, probably in 

 Southern California : said to be perennial and fruticose. The character, as to habit and foliage, 

 is taken from Mo^uin's description and may be erroneous. See under A. microcarpa. 



A. BARCLAYAN'A, Dietr. Slender, with long procumbent branches, somewhat mealy : leaves 

 obovate and obtuse, on short petioles, or the upper oblanceolate and acutish, 8 to 12 lines long, 

 rather thick, entire : fruiting bracts in small axillary clusters, cuneate-orbicular, a line broad, 

 the margin above the middle rounded, coarsely and acutely toothed. At Magdalena Bay, Lower 

 California, Barclay ; only imperfect specimens in the Kew herbarium. 



H- -H- Bracts orbicular, 2 to 2| lines broad, united, surrounded by a gash-toothed 



herbaceous margin. 



9. A. coronata, Watson. Stout, erect, a foot or two high, branching and leafy, 

 mealy : leaves lanceolate, entire, \ to 1 inch long, acute or acuminate, attenuate to 

 a short petiole or sessile : flower-clusters axillary, androgynous : fruiting bracts 

 strongly compressed, the margin nearly as broad as the body, sessile or shortly pedi- 

 cellate, the sides rarely slightly muricate : seed f line broad. Rev. Chenop. 114. 



Near Fort Mohave (Cooper] ; San Joaquin Valley, Contra Costa County, Brewer. 



*- H -i Fruiting bracts coriaceous, triangular-cordate, not herbaceously margined 

 nor muricate, united to above the middle : leaves oblong-ovate, opposite, sessile. 



10. A. decunibens, Watson. Branching from the base, slender and decum- 

 bent or procumbent, the stems becoming somewhat woody at base, densely hoary- 

 scurfy : leaves mostly opposite, cuneate-rounded at base, acute or acutish, J to 1 inch 

 long or less : staminate flowers in dense clusters in short interrupted terminal spikes; 

 calyx 5 -cleft : fruiting bracts sessile, slightly cordate at base, acute, 2 lines long and 

 broad, compressed, entire or slightly denticulate : seed nearly a line long. Proc. 

 Am. Acad. xii. 275. 



Near San Diego, Palmer. 



t- -i- -f- -i- Fmiting bracts 2 to 4 lines long, indurated or spongy, rhombic-ovate, 

 united; the sides more or less convex and usually conspicuously muricate ; 

 the margin someichat herbaceous and toothed. 

 -H- Leaves broadly obovate to ovate-oblong, alternate, entire: decumbent. 



1 1 . A. leucophylla, Dietrich. Stout, densely hoary-scurfy, decumbent or pro- 

 cumbent : stems a foot or two long, somewhat woody near the base : leaves thick, 

 ^ to 1J inches long, obtuse or acutish, cuneate at base, sessile, 3-nerved : staminate 

 flowers in dense clusters in very short terminal spikes ; calyx rather large, 5-cleft : 

 fruiting bracts in axillary clusters, sessile, 2| to 3| lines long, acute; the sides 

 usually conspicuously 2-crested ; the narrow margin obscurely toothed or entire : 

 seed 1| lines broad. Watson, Rev. Chenop. 117. Obione leucophylla, Moquin, 

 1. c. 109. 



On the seashore, from San Francisco to San Diego. Described by Moquin as perennial, but 

 probably only an annual like the last, which it much resembles in habit. 



H- -H- Leaves triangular-hastate to rhombic-ovate, the lower opposite. 



12. A. argentea, Nutt. Stout, erect or subdecumbent, densely mealy or scurfy, 

 \ to 1^ feet high, branching from the base : leaves rather thick, \ to 2 inches long, 

 acute or obtuse, petioled or the upper sessile : staminate flowers in dense clusters in 

 the upper axils or in short spikes ; calyx deeply 5-cleft : fruiting bracts shortly 

 pedicellate in axillary clusters ; the more or less dilated margins not reaching the 

 base, often bifid at the summit, sharply and deeply toothed ; the sides usually muri- 

 cate with herbaceously tipped projections or with a double toothed crest : seed a 

 line broad. Watson, 1. c. Obione argentea, Moquin. 



Sierra County, Lemmon. Frequent in the valleys eastward to Colorado and the Upper Missouri.
