larger, more branched and succulent than are native ones 

 in the Herbarium. It flowered in July and August. 



Desoe. A glabrous glaucous annual, with many simple 

 or branched stout, terete, erect or ascending stems six to 

 twelve inches high. Leaves succulent, very variable, 

 sometimes linear-spathulate, one to three inches long and 

 one-half to three-fourths of an inch broad, and coarsely 

 toothed or lobulate, at others much shorter and trisect or 

 pinnatisect with few very narrow linear acute entire seg- 

 ments about a line broad. Heads solitary at the ends of 

 the stems or branches, long-peduncled, one and a half to 

 two and a half inches broad, golden-yellow. Involucre 

 hemispheric, outer bracts oblong, green, with hyaline 

 margins, inner with very large rounded hyaline appendages. 

 Ray-flowers twelve to twenty, tube very short ; limb very 

 broadly oblong, obscurely crenate at the tip. Dish-flowers 

 very numerous, outer shortly flagon-shaped, base almost 

 cordate, contracted at the minute five-toothed mouth, 

 innermost smaller, nearly tubular. Achenes of the ray 

 short, very broad, dors ahy deeply furrowed, and with 

 three or four ventral thick wing-like ribs crowned by a 

 hyaline truncate and obliquely cleft tube; — of the disk 

 shorter, with two oblong parallel ventral swellings crowned 

 with a scale or annular corona. — J. D. H.
