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

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

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

 — Baliia confertiflora, DO 1. c. 657 ; Torr. & Gray, 1. u. — HiUs, California, common from near 

 the coast to the Sierra Nevada. 



Var. trifldum, Gray, 1. 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. confertiflora, var. trifida, Gray, Bot. Calif. 1. c. — With the ordinary form. Autum- 

 nal specimens, coll. by Parish, on the San Bernardino Mountains, are tomentose with longer 

 and looser wool. 



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

 peduncled. — Bahia tenuifolia, DC. 1. i;. — California, Douglas (lierb. IJC), Coulter. An 

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



# * Herbaceous, comnionlv and perhaps always perennials: lieads larger, mostly solitary or 

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

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

 variable. 



-I— Akenes glabrous, glabrate, or sparsely appressed-pilose, not glandular. 



E. CSespitosum, Uougl. Flobcosely 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 iucisely 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. tenuifolia, DC, but merely the most 

 slender form of the present species). — Moist or dry ground, common from jMontana 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 half-inch high, the main divergent forms are : — 



Var. latifolium, 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 from 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 paleiE 

 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 olisolete (as 

 occurs in other forms also). — Bahia arachnoidea, Fisch. & Lallement, Ind. Sem. Hort. 

 Petrop. 1842; Gray, PI. Fendl. 100, & Bot. Calif, i. 382. B. latifolia, Benth. Bot. 8ulph.30. 

 Eriopht/llum 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. hrachipoda. 

 Gray, Bot. C:^lif. 1. c, is a sea-shore form of this, with leaves thickish under exposure, beads 

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

 inter/ri folium occur in the Sierra, in groves of Sequoia gigantea. 



Var. achilleeoides, Ghay, 1. c. Lea\ cs pinnately parted or cleft, •v\ith the 3 to 5 

 divisions mostly narrow and laciniately incised or pinnatifid : beads somewhat corvmbosely 

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

 involucral bracts 9 to 13: akenes sparsely pubescent or gXahraie. ~ Bahia^ achillwoides, 

 DC. 1. c. B. lanata, var. arhillaoldes, Gray, Bot. Calif. 1. c. — ( ^ilifornia, near the coast. 



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

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

 parted into a few narrowly linear divisions: lieails solitary and long-pcduniled : involucre 

 half-inch high, hemispherical, dcjisely woolly, of loto i:! bracts: r:vysris niany.hu-ge: :ikcnes 

 usually somewhat pnliesieut : corolbi-tube sparsely bir.sute-ghmdular. — Brt/»Vi laiiata, Benth.
