206 COMPOSITE. 



= Pappus seldom if ever wanting; achenes somewhat cuneate. 



15. L. hirsntnla. 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 

 slsnder- 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 white 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. MONOLOPIA, 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. Acheues black, without pappus. Genus otherwise like 

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



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

 form naked monocephalous 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. gracilens, 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. Rays 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. 



I. 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, 

 % in. high or more, of linear bracts: receptacle convex: rays 68: 

 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.
