flowered; tegules few, about 20, subequal, erect, loose, thin, oblong- 

 linear, acute, ciliate, 6 mm. long; rays few, yellow; akenes pubescent. 



A species of the granitic rocks of the Wallowa Mountains, Oregon, at 

 2000 to 2500 m. altitude, collected by Mr. W. C. Cusick and distributed 

 under Nos. 1713, 1721, 3308 (type), 3310 and 3314. The species belongs 

 to the Virgaurea group, but is very distinct from any heretofore de- 

 scribed. 



Eucephalus gormani n. sp. 



A tufted perennial from stout woody creeping rootstocks: stems leafy, 

 erect, simple, 10-15 cm. high; whole herbage minutely glandular- 

 puberulent: leaves narrowly oblong to slightly oblong-lanceolate, sessile, 

 acute, mostly cuspidate, ciliate, thickish, 1.5 to 2.5 cm. long, with a promi- 

 nent midrib or occasionally triplinerved ; peduncles very short : heads soli- 

 tary, 1 cm. high: tegules in about 3 ranks, lanceolate to ovate-lanceolate, 

 acute or acuminate, scarious margined and ciliate, green or somewhat 

 chartaceous, the inner ones broadest: rays about 12, pinkish becoming

Dry rocky slopes, 5200 feet altitude, Mount Jefferson, Oregon, type 

 collected by M. W. Gorman, No. 2851, July 24, 1907. Most nearly 

 allied to E. paucicapitatus (Rob.) Greene, from which it differs in its 

 lower habit; absence of the sparse short pubescence on the herbage; 

 smaller heads; and especially in the firmer scarious-margined tegules, 

 most of which are distinctly broadened near the base.

Aster elmeri Piper, Bull. Torr. Club 29:645. 1902 (not Aster elmeri 

 Greene Pitt. 2:170. 1891).
