348 PROCEEDINGS OF THE AMERICAN ACADEMY 



peduncles and inflorescence subvillous ; leaves ovate, 4—6 lines broad, 

 acute, cordate to cuueate at base, upon a rather short petiole ; pedun- 

 cles stout, naked, 8 inches high, from a diffusely branched wootly base, 

 bearing a compound umbel of about 6 rays ; bracts large and folia- 

 ceous ; involucres large and turbinate, with erect acute teeth ; flowers 

 pale yellow, glabrous, 1^ lines long, the filaments very villous — Dis- 

 tinguished from the rare form of J^. umbellatum with a comjiound 

 umbel by the short erect teeth of the involucre and by the villous 

 pubescence. Collected in Plumas County, California, by Mrs. M. E. 

 P. Ames and J. G. Lemnion, in Long and Bear Valleys, apparently 

 abundant. 



Eriogonum (Virgata) Baileyi. Annual, slender, diflTusely 

 much branched, a foot high, glaucous and wholly glabrous excepting 

 the whorl of leaves at the base, which are densely whitc-toraeutose on 

 both sides, orbicular to broadly ovate, 3-G lines in diametei* ; bracts 

 small ; involucres narrow, a line long or usually less, open at the 

 throat, with obtuse teeth ; flowers pinkish white, J-| of a line long. — 

 Referred to E. gracile, van ejfusum, by Dr. Gray in the Revision of 

 the genus, but more nearly allied to £J. vimineum, which however is more 

 tomentose above the base, the involucres longer and contracted at the 

 mouth, and the flowers somewhat larger. E. gracile is of stricter 

 habit, with oblanceolate or oblong leaves, the turbinate involucres with 

 rigid acute teeth. Eastward of the Sierra Nevada, in the valleys and 

 on the foothills ; collected in North-western Nevada by Dr. Torrey 

 (n. 439), by W. W. Bailey and Watson on King's Survey (n. 1029- 

 1031), in Owen's Valley by Horn (n. 2851, California State Survey), 

 and in Arizona or Southern Utah by Dr. E. Palmer. 



Uktica Lyallii. Perennial, tall and rather slender, more or less 

 spinulose and hispid or becoming nearly glabrous ; leaves thin, cordate- 

 ovate, 3-6 inches long, on petioles 2-4 inches long, acute, coarsely 

 serrate, the teeth sometimes sparingly serrulate, the young leaves 

 densely hispid beneath ; stipules large, broadly oblong, obtuse ; flowers 

 in loose spreading or deflexed slender panicles, equalling or rather 

 shorter than the petioles ; perianth broadly ovate or nearly orbicular, 

 rounded at the apex, shorter than the broadly ovate achenium, which 

 is f of a line long — A very large leaved species collected by Dr. 

 Lyall in the Cascade Mts. in lat. 49 , and in Marin County, Cali- 

 forriia, by Bolander and Kellogg, the latter specimens more densely 

 hispid. A slenderly branched and nearly smooth plant collected by 

 Dr. Lyall at Vancouver's Island is probably the same. 



Urtica Breweri. Perennial, stout, tall and branching, grayish
