330 COMPOSITE. Eriophyllum. 



high, several or numerous in a compact cymose chister, mostly short-peduncled or subsessile : 

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

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

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

 the coast to the Sierra Nevada. 



Var. trifidum, Gray, 1. c. A form with small short leaves, simply 3-5-cleft into 

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

 1. c. B. confurti flora , var. trifida, 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. — Bahia tenuifolia, DC. 1. c. — California, Donrjlas (herb. \yC), Coulter. An 

 ambiguous foi-m with larger heads and rays, coll. at Sau Bernardino, Parish. 



* * Herbaceous, commonh' and perhaps iduavs perennials: beads laryer, mostly solitary or 

 scattered and conspicuously pedunculate: reci'ptaele 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. 



-1— Akenes glabrous, glabrate, or sparsch" appressed-pilose, not glandular. 



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

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

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

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

 longer than the pajijius, which is variable, sometimes vei-y short, sometimes obsolete. — Lindl.

 lanatum, Nutt. Gen. ii. 167; Hook. Fl. i. 315. Bahia lanata, DC. Prodr. v. 657; Torr. & 

 Gray, Fl. ii. 375, inch var. tenuifolia (which is not B. tenuifolia, DC, but merely the most 

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

 Columbia, and thence to S. California, under very various forms, which are indefinable as 

 species. Taking as the 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 heads rarely h,alf-inch high, the main divergent forms are: — 



Var. latifolium,. Gray, l. 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 from oblong to 

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

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

 of which 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 other forms also). — Bahia arachnoidea, Fisch. & Lallement, Tnd. Seni. Ilort. 

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

 Eriophyllum coispitosum, 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. hrachijpoda, 

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

 clustered and remarkaldy short-peduucled, and pappus larger. Forms connecting with var. 

 inteqri folium occur in the Sierra, in groves of Sequoia giijantea. 



Var. achilleeoides, Gray, 1. c. Leaves pinnately parted or cleft, with the 3 to 5 

 divisions mostly narrow and laciniately incised or pinnatifid : heads somewhat corymbosely 

 collected and rather short-peduucled : involucre hemispherical, 3 or 4 lines iiigh ; rays and 

 involucral bracts 9 to 13 : akenes sparsely pubescent or glabrate. — Bahia achilUeoides, 

 DC. 1. c. B. lanata, var. achillwoides, Gray, Bot. Calif. 1. c. — California, near the coast. 



Var. grandiflorum, Gray, 1. c. Rather strict and stout, densely M'oolly : leaves all 

 linear or the lower narrowly lanceolate or spatulate, laciniate-serrate or entire, or some 

 parted into a few narrowly linear divisions : heads solitary and long-peduncled : involucre 

 half-inch high, hemisjjherical, 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. B. lanata, var. grandi flora, Gray, Bot. Calif. 1. c. — California, valley of 

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