 fr. Aug.-Sept. 



Locs. — Orinda, San Pablo Creek, Jepson 14,275; Berryossa, Santa Clara Valley, B. J. 

 Smith 35. 



Refg. — Eryngium jepsonii C. & R. Contrib. U. S. Nat. Herb. 7:54 (1900), type loc. Orinda 

 Park, Contra Costa Co., Jepson 14,275; Jepson, Fl. W, Mid. Cal. ed. 2, 289 (1911), excluding

Eryngium elongatum C. & R. Contrib. U. S. Nat. Herb. 7:53 (1900), type loc. "near San 

 Francisco", Vasey in 1875; bracts becoming reflexedj otherwise much as in E. jepsonii C. & R. 



(ox char.). 



10. E. vaseyi C. & R. Coyote-thistle. Plants growing in shallow vernal 

 pools and showing two vegetative stages : earliest leaves all fistulous, jointed, and 

 basal, disappearing with the drying up of the pools and succeeded by leafy stems ; 

 stems stout, erect, more or less branching, commonly 8 to 13 inches (or sometimes 

 2 feet) high; blades of lower leaves narrowly oblanceolate, spinulose, somewhat 

 incised or bearing small lanceolate lobes below, narrowed below to broadly margined 

 petioles, the whole 4 to 8 inches long, the upper much shorter ; heads Sy^ (or 21/2) 

 lines high ; bracts spinose, spinulose toward the base, 6 to 10 lines long, much sur- 

 passing the bractlets ; bractlets similar, surpassing the flowers ; sepals longer than 

 the short styles. 



Pool beds, water-filled in winter, dry in summer, 25 to 1500 feet : west side Sac- 

 ramento Valley ; Coast Ranges from Mendocino Co. to Monterey Co. May-June, 

 fr. Aug.-Sept. 



Locs. — "Willows, Glenn Co., Davy 4300; Middle Eel River to Round Valley, Jepson 14,267; 

 Big Valley, Lake Co., Jepson 14,272 ; Vacaville, Jepson 14,161, 14,168 ; Little Oak, nw. Solano 

 Co., Jepson 1197, 14,162, 14,165 ; Elmira, Jepson 14,166 ; Suscol Hills, s. Napa Co., Jepson 14,269. 

 The VacaviUe and Elmira spms., cited above, are duplicates of collections, the unicates of which 

 were named by Coulter & Rose as E. vaseyi (Contrib. U. S. Nat. Herb. 7:57). Determinations 

 by us of the other material just cited rest on this initial naming. We have seen no satisfactory 

 material of E. vaseyi from Monterey Co., where the type of the species was collected.

11. E. oblanceolatum C. & R. Dog-thistle. Similar in flowering and fruit- 

 ing habit to E. vaseyi and likewise developing phyllodes in the winter pools ; bract- 

 lets surpassing the flowers, broadly scarious-margined at base, the outer spiny, the 

 inner entire ; styles longer than the sepals.

 petiole ; inflorescence beginning low and diffusely branching, the heads about 2^ 

 lines high ; bracts narrow and rigid, with a few spinose bristles and with or without
