Herbage densely tomentose, the leaves somewhat glabrate: 

 stems leafy, 1 m. or less high, sometimes very short or almost 

 none: leaves firm-coriaceous, entire, broadly ovate or oval, from 

 1 to nearly 2 dm. long, on petioles of various lengths: heads 

 short-penducled or subsessile, nearly hidden by the leaves : outer 

 bracts of the involucre oblong-lanceolate, foliaceous, usually ex- 

 ceeding the rays; inner bracts 1.5 to 2 cm. long: rays 5 to 9, 

 barely 1.5 cm. long: pappus forming a crown about the summit 

 of the achene, variously cleft, the lobes sometimes awn-like, some- 

 times broad and entire or fimbriate. 



In dry clayey soils at altitudes of 750 to 1400 m., in northern 

 Lower California (Jul. 7, 1885, Orcutt), San Diego Co. (Laguna,

46. VIGUIERA HBK. 



Ours shrubby plants with slender brittle stems and hispidu- 

 lous-scabrous petioled leaves, at least the lower of which are 

 opposite. Heads medium-sized, conspicuously pedunculate near 

 the ends of the branches, the peduncles not thickened at summit. 

 Bracts of the involucre herbaceous, imbricated. Bracts of the 

 receptacle persistent and embracing the lightly compressed or 

 4-angled disk-achenes. Ray-flowers yellow, neutral. Pappus of 

 two awns or acute paleae, one to each principal angle of the 

 achene, and two or more intervening short erose paleae on each 

 side. 



Leaves lanceolate: involucre green: achenes sparsely pubescent 



1. F. laciniata. 



Leaves ovate: involucre cinereous: achenes densely villous: var. Parishii of 



2. F. deltoidea. 



1. V. laciniata Gray, Bot. Mex. Bound. 89 (1859). 



Stems leafy to summit, branching to form a round-topped 

 bush 6 to 12 dm. high : herbage scabrous-pubescent, resinous : 

 leaves from pinnatifid to nearly entire, lanceolate from a broad 

 often hastate base, acute, 2 to 5 cm. long including the short 

 petiole, the veins very prominent on the under side: involucre 

 about 8 mm. high; outer bracts ovate with abruptly acuminate 

 spreading tips ; inner bracts narrow, erect : rays 1 to 1.5 cm. long :
