CIIRYSOPSIS RUTIIII.
Perennial, slender, silvery-pubescent, stoloniferous. Stems dif fusely branched, 1-3 dm. long, the branches ascending or decum bent, very leafy, densely so above ; leaves linear or some linear lanceolate, 2-5 cm. long, acuminate, entire, sessile, the old ones becoming longitudinally ribbed; heads solitary, or corymbosely disposed, about I cm. high ; peduncles 1.5-2 cm. long, densely glandular ; involucral bracts linear or linear-lanceolate, in 4-5 series, glandular on the back, the pale edges ciliate, the apex bearded ; rays bright yellow, elliptic-spatulate, 7-8 mm. long, slightly notched at the apex; corolla 5 mm. long, yellow, the seg ments triangular, sparingly ciliate, nearly erect ; pappus dirty white, slightly shorter than the corolla ; filaments and anthers glabrous; style glabrous, except the very sparingly glandular top; achenes pubescent.
Rocks in the Hiawassee Valley, eastern Tennessee.
A low stoloniferous species related to Chlysopsis graminifolia from which it differs conspicuously in being low, diffusely branched and bushy. Besides the very slender habit, the small acumi nate leaves, the glandular peduncles and narrower and more acuminate involucral bracts distinguish Chrysopsis Ruthii from C. graininifolia. The species is named for Prof. A. Ruth, of Knox ville, Tenn.
Perennial, coarse, very hispid throughout with shaggy hairs. Stem erect, 6-12 dm. tall, simple below, branched above, finely
channelled in age; leaves alternate, ovate-lanceolate to narrowly ovate, 5-14 cm. long, acuminate, remotely serrate with promi nent teeth, except near the base and apex, sessile or nearly so; heads 3.5-4.5 cm. broad, peduncled ; involucres broadly panulate, the bracts lanceolate or ovate-lanceolate, 8-14 mm. long, acute or somewhat acuminate ; corolla about 4 nun. long, the segments ovate, rather obtuse ; rays yellow, elliptic-oblong, 10-14 mm. long, undulately 3-toothed at the apex ; achenes obovate, more or less constricted at both ends, about 6 mm. long, winged (Plate 315).
In dry or rocky soil, Cullman, Alabama, October, 1885.
A very distinct species of the confused genus Si/phi/int, related to what I take to be S. asperrimum Hook., hitherto usually called S. scabeirimum. It is at once distinguished by the copious shaggy pubescence of its foliage as against the short retrorse pubescence of its relative. The peculiarly toothed leaves with their less rounded bases, and the smaller heads with their narrower bracts and shorter rays are additional distinguishing characters.
The species is named in honor of the veteran botanist of Ala bama, Dr. Charles Mohr, who for many years has furnished our collections with rare and unique plants from that interesting re gion.
