Erio^oiiiiiii saxicola 



Perennial from a stont woody multicipital rootstock: stems 

 numerous from the crown, about 5 dm. high, scape-like and 

 naked, glabrous and glaucous, moderately stout, about 4 mm. in 

 diameter: leaves basal, the blade coriaceous, ovate with a broad 

 rounded apeJc, densely tomentose below with short cottony 

 hairs, much less so above, the largest ones 25 mm. long, 17 mm. 

 wide, abruptly narrowed into the petiole from the truncate or 

 slightly cordate base; petioles glabrous and yellowish at the en- 

 larged slightly sheathing base, more or less lanate above, the 

 longest 6 or 7 cm, long: cymose inflorescence 3-rayed, the mid- 

 dle branch the longest (about i dm,), the lateral ones i or 2 cm. 

 shorter, each branch normally again three-branched, but the 

 middle one reduced to a single almost sessile involucre, the lat- 

 eral ones about 15 mm, long: flower heads sessile or nearly so: 

 involucres greenish-yellow, glabrous, narrowly turbinate, 4 mm. 

 high, the divisions marked by fluted ridges, the short lobes acut- 

 ish, 1 mm. long: calices sulphur-yellow, a dozen or more in a 

 cluster, articulated at the pedicel, 3 mm, long and as broad 

 across the top, exserted i or 2 mm. from the involucre on slen- 

 der pubescent pedicels, the tube portion i mm, long, lanate, the 

 lobes oblong, 2 mm. long, i mm. wide, obtuse, the margins some- 

 what undulate: stamens exserted 2 mm, a little paler than the 

 calices: pistils equalling the stamens, the slender stigmatic tips 

 very slightly hooked. 



The type is no, 8298, collected May 21, 1906, about three 

 miles south of Bishop, Inyo county, California, in the Sierra 

 foothills, growing about granite boulders. It is rather plentiful 

 at the type station, and occurs in similar situations at other 

 places in the vicinity. It is a relative of E. nudum^ but is suf- 

 ficiently distinct from that species, which is found only in the 

 western part of the State. A plant collected by Mrs. Austin and 

 Bruce in Goose Lake valley, Modoc county, their no. 2316, is 

 apparently the same, which would indicate an extended range 

 for the species along the eastern base of the Sierra,
