WOOTON AND STANDLEY—NEW PLANTS FROM NEW MEXICO. 189 
glandular above, the pubescence especially abundant on the branches of the 
inflorescence; lower leaves firm and thick, oblong-linear, 11 cm. long or less, 
15 mm. wide or narrower, acute, bright green, mostly glabrous, closely and 
sharply spinulose-dentate, sessile by narrow bases, the uppermost leaves sessile 
by broad, clasping bases, some of the leaves almost entire, obtuse; heads few, 
14 mm. wide and 12 mm. high or smaller, hemispheric, with numerous narrow, 
violet rays; bracts linear-subulate, green for two-thirds their length, the tips 
all spreading and some of the lowest bracts reflexed, unequal, densely and 
coarsely viscid-pubescent ; achenes almost or quite glabrous, 
Type in the U. S. National Herbarium, no, 495484, collected in the Mogollon 
Mountains on the Middle Fork of the Rio Gila, Socorro County, August 9, 1903, 
by O. B. Metcalfe (no, 440). Altitude about 2,250 meters. 
ADDITIONAL SPECIMENS EXAMINED: West Fork of the Gila, August 25, 1903, 
Metcalfe; Luna, July 28, 1900, Wooton. 
Similar to M. asteroides, but distinguished by its stouter stems and narrow, 
thick leaves, and especially by the coarse, glandular pubescence 
Machaeranthera pygmaea (A. Gray) Wooton & Standley. 
Macheeranthera tanacetifolia pygmaea A. Gray, Pl. Wright. 2: 74. 1853. 
Aster tanacetifolius pygmaeus A. Gray, Syn. Fl. 17: 206. 1884. 
Machaeranthera simplex Wooton & Standley, sp. nov. 
Perennial or biennial from a thick, somewhat woody root; stems several, 
clustered, very slender and wiry, erect, 40 cm. high or less, simple or bearing 
2 or 3 heads on short peduncles, reddish, glabrous below, sparingly cinereous 
above; leaves thin, green, oblanceolate to oblong-lanceolate, acute, tapering to 
the base, coarsely salient-serrate, nearly glabrous except on the ciliate margins 
and villous veins; heads about 12 mm. broad; bracts linear, with long, linear, 
spreading, green tips, cinereous, nowhere glandular; rays narrow, 8 to 10 mm. 
long. 
Type in the U. 8S. National Herbarium, no. 382533, collected in the Capitan 
Mountains at an altitude of 2,100 to 2,250 meters, August 31, 1900, by F. S. 
and Esther S. Earle (no. 390). 
This is near M. asteroides, but differs in having thin, oblanceolate, nearly 
glabrous leaves, few heads, and very slender, simple stems. 
Aphanostephus perennis Wooton & Standley, sp. nov. 
Slender perennial; stems wiry, erect, 830 cm. high or less, much branched, 
the branches ascending, rough-puberulent or hispidulous; leaves all linear, 
entire, bright green, 15 mm. long or less, cinereo-scaberulous; heads few, 8 or 9 
mm. broad, on slender peduncles; bracts numerous, much imbricated, elliptic- 
lanceolate, acute, puberulent; rays rather few, pinkish; achenes dark brown, 
nearly terete, almost glabrous. 
Type in the U. S. National Herbarium, no. 564549, collected at Knowles, 
July 29, 1909, by E. O. Wooton. 
This may be readily distinguished from our other species by its perennial 
root, wiry stems, narrow leaves, and harsh pubescence. 
Dicranocarpus dicranocarpus (A. Gray) Wooton & Standley. 
Heterospermum dicranocarpum A. Gray, Pl. Wright. 1: 109. 1852.

There is no doubt that the genera Dicranocarpus and Wootonia are the 
same, as suggested long since by Mrs. Brandegee and Mr. M. E. Jones. The 
types of the two genera came from the same general region, from localities 
probably not more than 100 miles apart. It is interesting to find that both are
