1904 | NELSON: ROCKY MOUNTAIN PLANTS 267 
distinguished from both by the nearly simple branches, the glandulosity of 
the whole plant, and the narrowly linear leaves, From the former also by 
the greener stems which lack the canescent harsh pubescence of that species ; 
from the latter also by a very different involucre. 
I dedicate this species to Mr. L. N. Goodding, who secured a most valua- 
ble collection of plants in southern Nevada and Utah, in fact, as will be 
noticed, most of the species of this paper. No. 667, from “rock crevices,” 
“The Pockets,”’ southern Nevada, April 30, I902. 
v Townsendia dejecta, n. sp.—Depressed-acaulescent, the caudex 
bearing a few heads in a small rosulate semisubterranean tuft: 
leaves linear-spatulate or oblanceolate, somewhat petioled, 1-2™ 
long (including the petiole), surpassing the heads, somewhat 
fleshy, green and apparently glabrous but under a lens appressed 
strigose on both faces: heads sessile at the base of the leaves, 
about 1° high; involucral bracts in 2-3 series, oblong ovate, 
mostly subacute, purple or some with green centers, ciliate mar- 
gined, otherwise nearly glabrous: rays white or possibly purple: 
disk flowers numerous, the corolla lobes purple: pappus white, 
similar in disk and ray flowers as are also the akenes: akenes 
brown, flattened, spatulate-cuneate, about 4™ long, wholly 
glabrous except for some obscure puberulence at the very base, 
as long as the pappus and disk corolla. 
Most nearly allied to 7. al/pigena Piper, from which it may be dis- 
tinguished by its absolute stemlessness, the strigose pubescence, the purple 
of the involucre, of the disk, and probably of the ray, and by the glabrous 
akenes wholly devoid of bidentate hairs. Townsendias with glabrous akenes 
are rather rare, 
Collected by Mr, Goodding in the Uintah Mountains, near Dyer’s Mine, at 
an altitude of about 3,000™. Type no, 1238, July 3, 1902. 
~ Machaeranthera verna, n.sp.— Perennial from thickened woody 
roots: stems several from the ligneous crown, erect, branched 
above, 4—6%™ high, striate, nearly or quite glabrous except above: 
leaves from linear to lanceolate, glabrous or sparsely crisped or 
ciliate-pubescent especially on the margins, spinously few-toothed 
on the margins; the uppermost reduced and bract-like, lanately- 
puberulent as are also the branchlets: heads corymbose-panicu- 
late: involucre 12-14™™ high and broad; its bracts imbricated 
in 5-6 rows, scarcely viscidulous, lightly sublanate, linear acu- 
minate, the slender tip green and at length reflexed: rays purple,
