1904] NELSON: ROCKY MOUNTAIN PLANTS 275 
pus of numerous linear-oblong obtuse scales half as long as the 
corolla-tube. 
The two related species are //. /ugens Greene and H. macroglottis Rydb., 
the species now described making the third in the series of long-throated 
forms (see Rydberg, Bull. Torr. Club 27:636). 
Type no. 880, by Mr. Goodding, who reports it as abundant in “rocky 
volcanic draws” near Diamond Valley, Utah; May Ig, 1902. 
’ Tetraneuris epunctata, n. sp—Caudex simple or with 2-sev- 
eral crowns: leaves crowded on the crowns, glabrate and bright 
green, with a few long whitish scattered hairs, wholly free from 
the punctate glands so usual in the genus, some microscopic 
resin particles present, narrowly spatulate or oblanceolate, 2-4™ 
long, the margined petiolar bases imbricated on the crowns but 
not involved in the usual wool of the other species: scapes sim- 
ple, ebracteate, 1 or less high, sparsely silky-canescent and 
obscurely granulate: heads large, 25-30" broad when fully 
expanded: involucre silky-lanate; the green tips of its oblong 
acute bracts mostly free from the wool: the bright-yellow rays 
about 12™ long: disk corollas penicillate glandular-pubescent 
on the lobes: pappus scales nearly as long as the disk corollas, 
obovate, abruptly long-acuminate. 
The type of this excellent species is no. 1236, collected by Mr. L.N. 
Goodding near the Dyer Mine in the Uintah Mountains, Utah, July 3, 1902. 
Most of the species in this genus are xerophilous plants and strictly vernal, 
occurring on broken ridges of the plains or on denudated foothills. In the 
species before us we have an inhabitant of moist subalpine slopes, occupying 
a belt from 9,000-12,000 feet in altitude. No. 1374 by the same collector 
was obtained above timber line. 
~ Tetraneuris eradiata, n. sp.— Densely silky throughout: caudex 
short, of one or more crowns, slightly lanate and covered with 
the expanded bases of the petioles: leaves crowded on the 
crowns, linear or narrowly oblanceolate, 5-8™ long, the short 
petiole margined and expanding at its scarious base: scapes 
slender, 12-25°" high: heads wholly eradiate, 1°" or more 
high, the disk almost orange or tinged with brown: pappus- 
scales obovate, glistening-white, tipped with a slender awn, 
including the awn almost as long as the silvery akene and 
scarcely shorter than the corolla.
