 awn which is somewhat longer. — Hills and plains along the eastern base 

 of the Mt. Diablo Range. 



2. S. palndosa, Greene. Stems several, 2 ft. high or more, strictly 

 erect: leaves subentire to laciniate-parted into long and very narrow 

 segments: head 50 — 75-flowered; bracts all tapering from a lanceolate 

 base into a long slender acumination: achene 2 lines long: pappus 

 brownish, the lanceolate palese little more than a line long, the barbellulate 

 awn 4 — 5 lines. — Low moist plains, from Marin Co. to Solano. 



3. S. Bolanderi (Gray), Greene. About 1 ft. high, the scapiform
