330 COMPOSITE. Eriophyllum. 



high, several or numerous in a compact cymose cluster, mostly short-pednncled or subsessile : 

 involucre oval or obovoid-oblong, of about 5 broadly oval thin-coriaceous bracts : receptacle 

 convex or low^-couical in the centre, not alveolate : rays 4 or 5 : paleai of the pappus 8 to 14. 

 — Bahia confertlflora, DC. 1. c. 657 ; Torr. & Gray, 1. c. — Hills, California, common from near 

 tlie coast to the Sierra Nevada. 



Var. trifidum, Gray, l. c. A form with small short leaves, simply 3-5-cleft into 

 oblong or short-linear lobes. — B. trijida, Nutt. Trans. Am. Phil. Soc. 1. c. ; Torr. & Gray, 

 1. c. B. con fert [flora, var. trijida, Gray, Bot. Calif. 1. c. — With the ordinary form. Autum- 

 nal specimens, coll. by Parish, on the Sau Bernardino Mountains, are tomeutose with longer 

 and looser wool. 



Var. laxiflorum, Gray, 1. c. Heads loosely fastigiate-cymose and mostly slender- 

 peduncled. — IJahia tenuifulia, DC. 1. c. — California, Doufjias (herb. DC), Coulter. Au 

 ambiguous form with larger heads and rays, coll. at San Bernardino, Parish. 



* * Herbaceous, commonlj' and perhaps always perennials: heads larger, mostly solitary or 

 scattered and conspicuously pedunculate: receptacle from convex or low conical to flat (even in 

 the same species): ligules 6 to 13, from quarter to half inch long, oblong or oval: leaves 

 variable. 



-)— Akenes glabrous, glabrate, or Sparsely appressed-pilose, not glandular. 



B. CSespitosum, Dougl. Floccosely white-woolly, many-stemmed from the root : leaves 

 in age witli upper face often glabrate ; lower ones from spatulate or cuneate to roundish in 

 outline, from incisely 3-5-lobed to pinnately parted, or the upper varying to linear and entire : 

 involucral bracts 8 to 12, oblong or oval: tube of disk-corollas mostly hirsute-glandular and 

 longer than the pappus, which is variable, sometimes very short, sometimes obsolete. — Lindl.

 Gray, Fl. ii. 375, inch var. tenuifolia (which is not B. ten\iifolia, DC, but merely tlie most 

 slender form of the present species). — Moist or dry ground, common from Montana to Brit. 

 Columbia, and tlience to S. California, under very various forms, whicli are indefinable as 

 species. Taking as tlie type the original of Pursh and Nuttall, with rather slender stems 

 a foot or more high, principal leaves somewhat palmately pinnatifid into narrow divisions, or 

 incisely cleft, and lieads rarely half-inch high, the main divergent forms are: — 



Var. latif olium, Gray, 1. c. The opposite extreme in foliage : stems commonly 

 2 feet long, branched and lax when growing in shade : leaves thin, dilated, from rhombic or 

 cuneate to oblong-lanceolate, 3-5-lobed and incised or dentate, the lobes frtnn oblong to 

 broadly lanceolate : peduncles comparatively short : rays 9 to 13 : corolla-tube either sparsely 

 or densely hirsute with gland-tipped hairs, much longer than the pappus, the rounded paleffi 

 of wliich do not exceed the breadth of the narrowly oblong-cuneate or narrower glabrous 

 akenes, commonly very short and forming a kind of crown, sometimes quite obsolete (as 

 occurs in otlier forms also). — Bahia arachnoulea, Fisch. & Lallement, Ind. Sem. Hort. 

 Petrop. 1842; Gray, PI. Fendl. 100, & Bot. Calif, i. 382. B. latifolia, Benth. Bot. Sulph.30. 

 Eriophiillum ccespitosum, Bot. Reg. t. 1167, is nearly this. — California, near the coast, in or 

 near Redwood forests, from Humboldt Co. to Santa Cruz. Bahia lanata, var. brachi/poda, 

 Gray, Bot. Calif. 1. c, is a sea-sliore form of this, with leaves thickish under exposure, heads 

 clustei-ed and remarkably short-peduncled, and pappus larger. Forms connecting with var. 

 integrifolium occur in the Sierra, in groves of Sajuoia (ji<;antea. 



Var. achillseoides, Gray, l. c. Leaves pinnately parted or cleft, with the 3 to 5 

 divisions mostly narrow and laciniately incised or pinnatifid : heads somewhat corymbo.sely 

 collected and rather short-peduncled : involucre hemispherical, 3 or 4 lines high ; rays and 

 involucral bracts 9 to 13: akenes sparsely pubescent or glabrate. — Bahia achi/la-oides, 

 DC. 1. c. B. /anata, var. arhilla'oides. Gray, Bot. Calif. 1. c. — California, near tlie coa.st. 



Var. grandiflorum, Gray, 1. c. Rather strict and stout, densely woolly : leaves all 

 linear i)r the lower narrowly lanceolate or spatulate, laciniate-serrate or entire, ur .some 

 parted fnt(7 a few narrowly linear divisions : heads solitary and long-peduncled : involucre 

 lialf-inch high, hemispherical, densely woolly, of 10 to 13 bracts : rays as many, large : akenes 

 usually somewhat pubescent: corolla-tube sparsely hirsute-glandular. — Bahia lanata, Benth. 

 PI. Hartw. 317. /J. lanata, var. (jrandi flora. Gray, Bot. Calif. 1. c. — California, valley of 

 the Sacramento. (Guadalupe Island, off Lower California.)
