 heads. — Walp. Eepert. vi. 106 ; Benth. & Hook. Gen. ii. 243. Ilelogyne, Beuth.

Neither of the two known species have yet been found within the actual limits of the State, one 

 being farther south, the other southeast. 



1. H. fasciculata, Walp. Scales of the involucre very numerous and closely 

 appressed, scarcely striate : akenes slender, ilattish, hispid on the lateral angles : 

 pappus of 2 or 3 almost barhellate awns and as many broad chafly scales which are 

 truncate and lacerate at the summit : leaves pabnately 3 - 5-parted or cleft, and 

 with the divisions iimxmia-lohQd. — Helogyne fasciadata, Benth. Bot. Sulpli. 1. c. 



Var. Xanti, Gray, with the leaves round-reniform and mostly only obscurely 

 lobed. — Proc. Am. Acad. v. 158. 



Lower California, Magdalena Bay, Hinds. Cape San Lucas, Xantus, the variety. 



2. H. pluriseta, Gray. Scales of the involucre striate, looser and fewer (20 to 

 25)*: akenes shorter, terete - 5-angular, pubescent: pappus of 10 to 12 slender 

 barely scabrous awns or bristles and as many narrow acute or poiiited chatly scales : 

 leaves small, acutely and irregularly cleft or incised. — Pacif. E. Ptep. iv. 90, t. 9. 



San Bernardino Desert to Williams' River and canons of the Colorado, Bigclow, Newberry, 

 Parry. 



2. EUPATORIXJM, Tourn. 



Head 3 - many-flowered. Involucre various. Pteceptacle naked. Corollas 5- 

 lobed or 5-toothed. Akenes 5-angled, with no intermediate ribs. Pappus of 

 numerous rather rigid capillary scabrous bristles, forming about a smgle series. — 

 Perennials, mostly with opposite leaves. 



A huge and widely dispersed genus, copious in the Atlantic States, extremely scanty in those 

 of the Pacific, two species barely reaching California. 



1. E. occidentale, Hook. Almost glabrous, slightly glandular, a foot or two 

 hi^li from a sulfrutesceut base : leaves commonly more or less alternate, on very 

 short petioles, ovate, triple-ribbed near the base, somewhat serrate : corymbs small 

 in a crowded panicle: heads 15-25-fiowered : scales of the involucre m nearly a 

 single series, shorter than the pink or pinkish flowers. 



From eastern slopes of the Sierra Nevada south to Elibetfs Pass and the Yosemite Valley ; not 

 rare in Nevada and the interior of Oregon, in canons, &c. 



2. E. sagittatum, Gray. Minutely puberulent : leaves all opposite, petioled, 

 hastately sagittate, entire : heads single or in threes at the ends of the diverging 

 branches, peduncled : involucre imbricated, cylindrical, 30 - 40-fiowered ; the scales 

 coriaceous, appressed, with conspicuous foliaceous spreading tips : akenes glabrous 

 with the sharp angles hispid. — PL Wright, i. 88, note. 



Southeastern part of Cahfornia probably ( 294, coll. Coulter), and adjacent parts of Mexico. 



3. BRICKELLIA, Ell. 



Head several -many-flowered. Involucre of imbricated striate-nerved scales, the 

 outer shorter. Receptacle naked. Corollas slender, 5-toothed or with 5 short 

 lobes. Style bulbous at base, the branches commonly thickened upward. 

 Akenes 10-striate or ribbed. Pappus of numerous scabrous or barbellate capillary 

 bristles, about in a single series. — Herbaceous perennial or partly shrubliy plants, 

 commonly rather glandular or viscid or dotted, most resembling Enpatorkm, except 

 in the many-ribbed or striate akenes ; the flowers Avhite, whitish, or flesh-color. — 

 Gray, PI. Wright, i. 84. Brichellia, in part, Bulbostylls, & Clavigera, DC. 



A genus of about 40 species, with head.iuarters southeast of California, but scantily represented 

 Avithin the State.
