Parthenopsis Kellogg, Proc. Calif. Acad. 5: 100. 1873. 



Perennial herbs with tall leafy stems, somewhat woody at the base, and petioled, alternate 

 leaves with broad blades. Heads large, terminal or in the upper axils, radiate. Involucre 

 hemispheric ; bracts in 3 or 4 series, broadly oval, or the intermediate ones suborbicular, puber- 

 ulent, faintly nerved. Receptacle flat, naked, slightly alveolate. Ray-flowers ligulate, fertile; 

 ligules spreading, entire or 2- or 3-toothed at the apex, 7-9-nerved. Disk-flowers hermaphro- 

 dite, perfect; tube glandular-hispid, very short; throat elongate, cylindro-campanulate ; limb 

 5-toothed. Anthers obtuse at the base. Style-branches thick, hispidulous, truncate at the 

 apex. Achenes short-linear, angled, striate, muricate, not hairy; pappus wanting.

Parthenopsis maritimns Kellogg, Proc. Calif. Acad. 5: 101. 1873. 



An erect sparingly branched herb; stem 1-2.5 m. high, often woody at the base; leaves 

 alternate, petioled; blades thin, 5-15 cm. long, 3-12 cm. broad, cordate, crenate-dentate, 

 minutely puberulent, more or less 3-5-ribbed; outer involucral bracts ovate, entire, herbaceous, 

 the intermediate ones suborbicular, the inner rounded, oval, more membranous and erose on 

 the margin, all indistinctly veined and puberulent; ligules 13-20, about 2 cm. long, normally 

 entire and acute but often irregularly toothed at the apex; achenes angled, about 12-nerved, 

 papillose-roughened. 



Type locality: California. 

 Distribution: Southern California. 



2. Venegazia deltoidea Rydberg, sp. nov. 



An erect slender branched herb; stem 5 dm. high or more, somewhat woody at the base, 

 terete, purplish, sparingly puberulent; leaves alternate; petioles 2-3 cm. long; blades deltoid-lan- 

 ceolate, 5-7 cm. long, 2-3 cm. broad, thin, puberulent on both sides, dentate with broadly triang- 

 ular acute spreading teeth, except at the entire acute apex; peduncles slender, about 1 dm. long; 

 involucre hemispheric, about 1 cm. high, 1.5 cm. broad; outer bracts ovate with oblong reflexed 

 foliaceous tips, the intermediate and inner ones broadly oval, puberulent, more membranous 

 than in the preceding species, the innermost delicate and cream-colored; ligules 15-18, about 

 15 mm. long and 5-6 mm. broad, entire at the apex; achenes linear-oblong, 12-ribbed, papillose. 



Type collected at Sangal, northern Lower California, April 7, 1886, Orciitt (herb. Columb. 

 Univ.).

7. CLAPPIA A. Gray, in Torr. Bot. Mex. Bound. Surv. 93. 1859. 



Low undershrubs with alternate fleshy leaves. Heads radiate, solitary, peduncled at the 

 ends of the branches; peduncles slightly thickened below the head. Involucre campanulate; 

 bracts impressed-striate, obtuse, in 3-4 series, those of the inner two subequal, of the outer 

 much shorter. Receptacle convex, setose-fimbiate, alveolate. Ray-flowers pistillate, fertile; 

 ligules linear, 3-dentate at the apex. Disk-corollas numerous, fertile; corollas glabrous; tube 

 cylindric; throat campanulate; limb with 5 oblong lanceolate teeth. Anthers linear, obtuse 

 at the base, with lanceolate tips. Style-branches hispidulous, with ovate tips. Achenes 

 oblong, obscurely 6-IO-costate, hirtellous. Pappus of 15-25 barbellate bristles, somewhat 

 squamellate below.
