WOOTON AND STANDLEY—NEW PLANTS FROM NEW MEXICO. 191 
acute, 5 mm. long or less, appressed-pubescent; rays bright yellow, conspicuous, 
obovate-spatulate; achenes 5 mm. long, cuneate-obovate, brown, glabrous, closely 
invested by the pales. 
Type in the U. 8S. National Herbarium, no. 563951, collected at Cloudcroft, 
in the Sacramento Mountains, August 24, 1899, by E. O. Wooton. 
A species of the section Verbesinaria, but very unlike anything listed for 
the section by Robinson and Greenman in their revision of the genus.’ It has 
larger heads than most members of the section.

Hymenopappus fisheri Wooton & Standley, sp. nov. 
Probably biennial, from a long, slender root; stems several, erect, stout, 30 
to 40 cm. high or more, leafy, the leaves gradually reduced toward the top; 
basal leaves not seen; cauline ones large, once pinnatifid into narrowly oblong 
to broadly linear, obtuse segments, densely arachnoid beneath, above sparingly 
woolly when young, but soon glabrate and bright green; heads numerous, 
corymbose, about 8 mm. in diameter, on slender peduncles; bracts sparingly 
tomentose, obovate, 5 mm. long, with thin, yellow, scarious tips; corolla bright 
yellow, glandular, the lanceolate lobes about equaling the campanulate throat; 
achenes dark brown, nearly naked on the faces, densely villous-ciliate on the 
angles; pappus conspicuous, about equaling the diameter of the achene at the 
summit. 
Type in the U. S. National Herbarium, no. 564948, collected near Nara Visa, 
in clay and sandy soil, September 8, 1910, by Mr. Geo. L. Fisher (no. 16). 
Also collected at Nara Visa, June 12, 1911, Fisher 177. 
The plant is suggestive of H. artemisiaefolius DC., but the bracts lack the 
very broad, white margins of that species, the leaf segments are narrower, and 
the corollas are bright yellow instead of nearly white. 
Hymenopappus nudatus Wooton & Standley, sp. nov. 
Perennial, 380 to 50 cm. high, with several stems clustered at the top of a thick, 
black root; leaves practically all basal, 10 cm. long, twice pinnate into linear 
divisions, densely arachnoid, the petioles very densely so, their bases covered 
with long, white wool; stems scapose, densely arachnoid, bearing but 1 or 2 
much reduced leaves; heads few, 1 to 5, large, 12 to 15 mm. broad, on long, 
stout peduncles; bracts 8 mm. long or less, unequal, obovate or oblong, with 
scarious stramineous tips, densely arachnoid; corolla pale yellow, the oblong- 
ovate, obtuse lobes not more than one-third as long as the tube; achenes densely 
silky-villous with tawny hairs; pappus of prominent scales nearly 2 mm. long. 
Type in the U. S. National Herbarium, no. 495226, collected in the Burro 
Mountains, Grant County, altitude 1,650 meters, June 6, 1903, by O. B. Metcalfe 
(no. 107).
