190 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM. 
included in Dalla Torre and Harms’s Genera Siphonogamarum, but with an 
interval of just one hundred genera between the two! 
Gymnolomia brevifolia Greene, sp. nov. in herb. 
Perennial; stems 50 to 60 cm. high, slender, brownish, with sparse, short, 
appressed, grayish pubescence; leaves ovate, rhombic-ovate, or elliptic, or the 
lowest oblanceolate, 20 to 40 mm. long, 10 to 20 mm. wide, acute, entire or 
obscurely serrate, the upper on short, winged petioles, the lowest on more 
slender petioles 10 mm. long, appressed-pubescent, scaberulous above, bright 
yellowish green; heads 10 mm. in diameter; bracts lanceolate, acuminate, 
canescent; rays showy, bright yellow; achenes obovate, glabrous, dark brown, 
without pappus. 
Type in the U. S. National Herbarium, no. 495518, collected in the Mogollon 
Mountains on the West Fork of the Rio Gila, altitude 3,300 meters, August 15, 
1903, by O. B. Metcalfe (no. 511). 
Ividently this is closely related to G. multiflora, but not more so than is 
G. longifolia. It is distinguished especially by its broad and remarkably short 
leaves. It seems to grow at a far higher altitude than most of our species of 
the genus. 
Helianthus canus (Britton) Wooton & Standley. 
Helianthus petiolaris canescens A. Gray, Pl. Wright. 1: 108. 1852, not H. 
canescens Michx. 
Helianthus petiolaris canus Britton, Mem. Torrey Club 5: 334. 1894. 
This seems to be worthy of specific rank. It is nearest H. petiolaris, but in 
general appearance is very different, chiefly because of the abundant white 
pubescence on leaves and stems. The pubescence of the peduncles is of long, 
spreading hairs, while in H. petiolaris it consists of short, appressed ones. 
Helianthus neomexicanus Wooton & Standley, sp. nov. 
Tall, branched perennial; stems comparatively slender, reddish, hispid or 
hispidulous up to the inflorescence; leaves all except the uppermost opposite, 
on slender petioles one-fourth to one-third as long as the blades, these ovate- 
lanceolate, thick, 8 to 15 em. long, 6 em. wide or less, rounded or narrowed 
and acute at the base, attenuate or long-acuminate at the apex, sparingly ser- 
rate with low teeth, scabrous on the upper surface, beneath soft-villous; heads 
rather few, the disk 15 mm. broad, on long, slender, densely canescent pedun- 
cles; bracts lanceolate, with long, abruptly acuminate, spreading tips, ciliate 
below the middle, scaberulous on the back, 13 mm. long or less; achenes not 
seen. 
Type in the U. 8. National Herbarium, no. 563826, collected at Mangus 
Springs, August 19, 1902, by E. O. Wooton. 
It is not certain that this is a perennial plant, but in its various character- 
istics it agrees better with the perennial than the annual species. We have only 
the upper branches. 
The pubescence of the lower surface of the leaves is very different from that 
found in any of our other New Mexican species, exactly matching that of the 
southeastern Helianthus tomentosus Michx. 
Verbesina oreophila Wooton & Standley, sp. nov. 
Tall plant, probably perennial, 1 meter high or more; stems erect, stout, not 
winged, minutely puberulent; leaf blades triangular-lanceolate to deltoid-ovate, 
8 to 11 cm. long, 7 cm. broad or less, acute, narrowed at the base to a short, 
slender petiole, coarsely serrate, scaberulous on the upper surface, beneath 
soft-pubescent; heads numerous, about 12 mm. in diameter, loosely cymose, 
on slender, naked peduncles; bracts oblanceolate, linear-oblong or lanceolate,
