slightly pubescent on both surfaces, slightly revolute, entire, or rarely 
obscurely pinnatifid at the base of the 2 to 5 scattered setz, 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, 25-30-flowered, the 5 
oblong obtuse plane bracts smooth, ciliate at the tips, faintly marked with 
elongate glandular dots: rays ovate-oblong, 4 mm. long: pappus clear- 
white, in the disk of 5 or 6 elongate scabrous sete 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.

tonio (Pringle, no. 5760), Cuicatlan (Nelson, no. 1598, L. C. Smith, 
no. 422), Nicaragua, Segovia (CErsted 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 
r procumbent from woody or suffruticose bases, rarely ascending with sub- 
simple branches above: heads many (30-90)-flowered. 
ig 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 sete : 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 em. 
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 
xe 5 mm. long, more or less pubescent with short recurved unequally 
bidentate hairs. — Pl. Wright. ii. 69, in Torr. Bot. Mex. Bound. 73, in
