 4 or 5, or in ray-flowers reiluced to a sin<rle one, in some plants all obsolete. 



— S. E. California, near San Bernardino, W. G. Wright, Lemmon, the latter with 

 obsolete or unipaleaceous pappus. 



■t- t- Involucre and whole herbage either glabrous or minutely soft-pubescent, 

 no hirsute hairs : heads middle-sized : pappus of firm ovate paleas abruptly 

 attenuate into an awn, the whole as long as the akene : leaves rather fleshy, 



++ Narrowly linear, quite entire. 



B. CAKXOSA, Greene in litt. Stem with some minute tomcntulose pubescence, 

 glabrate ; bracts of the involucre about 7, oblong, obtuse, thickisli-herbaceous, 

 smooth, at maturity carinate, having a very strong and salient midnerve and 

 an obscure distant lateral pair; rays oblong; akenes densely hispidulous-canes- 

 cent; pappus-pale<E 4, rarely 5, subulate-awned. — Salt marsh at Vallojo, on the 

 Bay of San Francisco, E. L. Greene, April, 188:>. 



B. Clevelandi. Branches and peduncles slightly pubescent ; bracts of invo-

 rays oval ; young akenes minutely scabro-hispidulous ; paleac of pappus slcnder- 

 awned, only 2 in disk and ray. — Near San Diego, Cleveland, 1874.

 coll. by Slillman. 



§ 2. DiCH^TA. {Dichceta, Nutt.) Pappus (occasionally wanting) of two forms, 



* Unlike in disk and raj', in both of about 5 fimbriate-laciniate paleaj, in the 



former awned, in tlie latter mostly muticous : leaves entire. 



B. Palmeri, Gray, Bot. Calif, i. 37G, is only of Guadalupe Island off Lower 

 California, Palmer. 



* * Not unlike in disk and ray, composed in both of truncate or muticous 



short paleoe between 2 or 3 awned ones or naked awns. 



H- Rays hardly exsertcd : leaves all entire : pappus of 3 to 5 awns and at least 

 twice as many squamellate narrow laciniate palea;. 



B. MARiTiMA, Gray. Farralones Islands. Should be collected anew. 

 +- •<- Rays usually exserted : pappus sometimes wanting : some of the leaves 



laciniate or pinnatifid: involucral bracts of the next section. — Dicliata, 'iHutt. 



B. FuEMONTi, Gray. Leaves slender; pappus of 4 slender awns and of nar- 

 row entire or 2-cleft small paleJE. 



B. uLiGiNOSA, Gray. Leaves linear or broader, the lower once or twice pinna- 

 tifi<l ; pappus of 2 or sometimes 3 chaflTy awns and of broad truncate laciniate 

 palesE. — Diclucta ulii/inoaa, Nutt. 1. c.
