Var. Parishii (Wats.) Hall, comb. nov. B. Pariskii Wats., 

 Proc. Am. Acad. xxiv. 83 (1889). Plant very slender, seldom 

 over 1.5 dm. high : stem simple to much branched above : herbage 

 pubescent with loose hairs: leaves narrowly linear, acute or ob- 

 tuse, mostly pinnately cleft into one to several pairs of slender 

 lobes, rarely all entire: involucre only 2 to 4 mm. high; bracts 

 8 to 12, scarcely enfolding the ray-achenes and the midvein not 

 prominent : ray-flowers 8 to 12 ; ligules about 3 mm. long : style- 

 tips truncate-apiculate : achenes linear, with truncate summit, 

 sparsely and minutely pubescent: pappus none in the typical 

 form. Known only from the type locality ; namely, on clay hill- 

 sides at about 450 m. alt. in Waterman Canon, near San Ber- 

 nardino: May 29, 1888, Parish, no. 2041 (duplicate type), in 

 part; May 8, 1895, Parish, no. 3642, in part. 



Var. Parishii f. varia Hall, form. nov. Pappus of 6 to 10 

 quadrate or ovate paleae with erose summits, some of them pro- 

 vided with awns as long as the corolla. Claremont, Feb. 10. 

 1897, Chandler. Corresponds to the typical form of B. aristata 

 and of B. aristata affinis, so far as pappus is concerned. 



Var. Parishii f. quadrata Hall, form. nov. Pappus of 6 to 10 

 quadrate paleae only half the length of the corolla-tube, their 

 summits erose-truncate. At the type locality of var. Parishii. 

 Parish, nos. 2041, in part, and 3642, in part, the remaining plants 

 gathered under these numbers differing only in the eppapose 

 achenes. Bears the same relation to f. varia that B. aristata f. 

 mutica does to typical B. aristata, and similarly corresponds to 

 f. truncata of var. affinis. 



66. MONOLOPIA DC. 



White-woolly annuals with mostly alternate sessile leaves and 

 long-peduncled heads of golden-yellow flowers. Involucre hemi- 

 spheric, its bracts either distinct to near the base or united into 

 a cup with broad or triangular teeth. Receptacle globular or 

 conical in our species, naked. Ray-corollas with ample 3 or 4- 

 toothed or -lobed ligule and bearing at the orifice on the opposite 

 side of the style a roundish denticulate appendage ; lobes of disk- 

 corollas somewhat hairy. Achenes obovoid, angular, black. 

 Pappus none.
