slightly pubescent on both surfaces, slightly revolute, entire, or rarely 

 obscurely pinnatifid at the base of the 2 to 5 scattered setie, faintly punc- 

 tate-dotted in 2 or 4 lines: peduncles axillary or terminal, capillary, 1 to 

 3 cm. long, 2-5-bracteate : involucre 5 mm. high, 2j-30-flowered, the 5 

 oblong obtuse plane bracts smooth, ciliate at the tips, faintly marked with 

 elongate glandular dots : rays ovate-oblongs 4 mm. long : pappus clear- 

 white, in the disk of 5 or G elongate scabrous setae 3^ to 5 mm. long, 

 and many unequal shorter capillary ones ; in the ray generally fewer : 

 akenes 3 or 4 mm. long, setose or glabrate. — Sch. Bip. in Seem. Bot.

 no. 422). Nicaragua, Segovia (Qilrsted Jide Benth. 1. c). Without 

 authentic specimens, it is impossible from the description alone to dis- 

 tinguish Bentham's plant from De Candolle's. In the Oaxaca material, 

 which is apparently all the same species, the suffruticose character is found 

 only in Mr. Pringle's plant. 



* * * Perennials, the stems subsimple or sparingly branched, mostly decumbent 

 or procumbent from woody or suffruticose bases, rarely ascending with sub- 

 simple branches above : heads many (30-90)-flowered. 



P. longipes, Gray. The glabrous slender densely leafy stems form- 

 ing tufts or depressed mats, including the long scape-like peduncles 1 ^ or 



2 dm. high: leaves thickish, linear, mucronate, 2 to 4 cm. long, 1^ to 



3 mm. wide, bearing conspicuous marginal glands and 2 or 3 pairs of 

 basal setae : peduncles 6 to 14 cm. long, naked or few-bracteate : involucre 

 broadly campanulate, 6 or 8 mm. high, 50-90-flowered ; the 12 or 15 

 plane linear acutish bracts each bearing a large apical gland and rarely 

 one or two toward the base: rays bright yellow, narrowly oblong, 1 cm. 

 or less in length ; disk-pappus 20 to 40 very unequal subbiseriate capil- 

 lary upwardly scabrous bristles, the longest 4 to 6 mm. long, the shorter 

 outer ones generally more slender ; ray-pappus 2 slender setulose awns 

 3 to 5 mm. long, and rarely a few reduced bristles at the base : akenes 4 

 or 5 mm. long, more or less pubescent with short recurved unequally 

 bideutate hairs. — PI. Wright, ii. 69, in Torr. Bot. Mex. Bound. 73, in
