206 COMPOSITE. 



= = Pappus seldom if ever wanting; achenes somewhat cuneate. 



15. L. hirsutnla. Stout and low, from a strictly annual root, mostly- 

 branching very freely : the whole herbage rather roughly short-hirsute: 

 leaves broadly linear, often with saliently projecting scattered teeth, the 

 lower conspicuously connate, sheathing the stem: involucral bracts obo- 

 void, obtuse or acutish: rays oblong: achenes mostly very smooth, 

 rounded at summit, manifestly compressed; pappus of 2 brownish very 

 slender-subulate aristiform bristles. — Plentiful on open rocky and grassy 

 hills along the seacoast, from Marin Co. southward. May, June. 



16. L. gracilis (DC). Whole habit and aspect of n. 13, but achenes 

 linear-cuneate, with pappus of while lanceolate or ovate slender-awned 

 palese, or the paleae sometimes almost obsolete. — Very plentiful and var- 

 iable; often very small, slender and simple, not rarely as large as L. 

 chrysostoma. April — June. 



53. M02JOLOPIA, De Candolle. Annuals white with floccose wool. 

 Leaves alternate, not linear, toothed or entire. Kay-corollas with ample 

 ligule, bearing at base, and opposite the ligule, a rounded denticulate 

 appendage. Achenes black, without pappus. Genus otherwise like 

 Laslhenia, and too near it; but also as easily referable to Eriophyllum. 



1. M. major, DC. Stout, nearly simple, or with several pedunculi- 

 form naked monoeephalous branches, 2 ft. high; expanded heads more 

 than 1 in. wide: bracts of involucre joined into a broad-campanulate toothed 

 cup: achenes 2 lines long. — In rich fields, or on hillsides. May. 



2. M. grracilens, Gray. Slender, diffusely paniculate, bearing scat- 

 tered short-peduncled heads less than 1 in. wide: bracts of involucre 

 distinct to the base: achenes 1 line long. — Plentiful on Mt. Diablo near 

 the summit, thence southward to the Santa Cruz seaboard. May — July. 



54. ERIOPHYLLUM, Lagasca. Ours mostly suffruticose, floccose, 

 and with divided leaves. Involucres oblong or campanulate, the bracts 

 of firm texture, permanently erect. Bays few, short and broad. Disk- 

 corolla with distinct slender proper tube. Style-tips truncate, obtuse, 

 or obscurely conical: Achenes clavate-linear to cuneate-oblong, mostly 

 4-angled. Pappus of nerveless and mostly pointless hyaline paleae. 



* Suffruticose; heads smallish, terminally clustered. 



1. E. staechadifoliuin, Lag. Stem and lower face of leaves white 

 with a close pannose tomentum; shrub much branched, 2 — 5 ft. high, 

 very leafy throughout: leaves subcoriaceous, cut into linear pinnate 

 divisions: heads compactly corymbose-cymose; involucres oblong, angular, 

 34 in. high or more, of linear bracts: receptacle convex: rays 6 — 8: 

 pappus-palese 8—12, the 4 over the angles of the achene somewhat 

 longer. — Sandy hills, and slopes of bluffs near the sea only. May — Dec.
