194 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM. 
lanceolate, acute, 6 mm. long or less, light green; rays oblong, rather bright 
yellow, 6 mm. long and 3 mm. wide or smaller; achenes striate, glabrous. 
Type in the U. S. National Herbarium, no. 497842, collected on open slopes 
on Hillsboro Peak, at the south end of the Black Range, May 27, 1904, by O. B. 
Metcalfe (no. 938). Altitude 3,060 meters. 
Most closely related, perhaps, to S. pentodontus, but with very different 
leaves and pubescence. 
Senecio remifolius Wooton & Standley, sp. nov. 
Perennial, multicipitous, from a rather stout, creeping or ascending rootstock ; 
stems scapiform, 25 cm. high or lower, glabrous, slender; basal leaves linear- 
oblanceolate, glabrous, or with an obscure and very sparse tomentum visible 
only under a lens, about 60 mm. long and 8 mm. wide, obtuse, entire or with 
3 or sometimes a few more shallow teeth, thick and fleshy, deep green, gradually 
tapering at the base into a slender petiole as long as the blade or longer; lower 
cauline leaves like the basal ones but smaller; upper ones linear, sessile by a 
somewhat widened base; stems sometimes with an obscure tomentum in places ; 
branches of the inflorescence several, ascending, each bearing 1 to 3 rather long- 
pedunculate heads, these campanulate, about 12 mm. high; peduncles naked 
or with a few bractlets; involucral bracts 10 to 12, linear-lanceolate, acute, 
with membranous margins, about 7 mm. long; rays oblong, pale yellow, 10 mm. 
long and 2.5 mm. wide or smaller; achenes striate, ciliolate along the angles. 
Type in the U. 8. National Herbarium, no. 690231, collected along Willow 
Creek, August 8, 1900, by E. O. Wooton. 
Similar to the preceding but with different leaves, heads, and achenes, 
Senecio sacramentanus Wooton & Standley, sp. nov. 
Erect from a cluster of rather fleshy roots, 70 cm. high or less; stems mostly 
simple below but paniculately branched above, sparingly tomentose below, 
densely so above, the pubescence densest about the nodes; lee ves lanceolate to 
triangular-lanceolate, 14 em. long or less and 5 em. wide or narrower, abruptly 
acuminate, coarsely salient-dentate, tapering, truncate, or cordate at the base, 
sparingly puberulent beneath, glabrous above, bright green, thin; petioles of 
the lowest leaves 7 em. long, slender, dilated and clasping at the base, those of 
the upper leaves shorter and winged, the uppermost leaves sessile and often 
clasping by a broad base; stems leafy throughout, the upper leaves considerably 
smaller than the others ; inflorescence much branched, of paniculate racemes; 
heads very numerous, small, 10 mm. long and 9 mm. wide or less, rather nar- - 
rowly campanulate, nodding; bracts about 8, rather broadly oblanceolate, acute, 
with membranous, light-colored margins; heads subtended by 2 or 3 short, fili- 
form bracts; rays none; achenes light chestnut colored, striate, with abundant 
soft, barbellate pappus. 
Type in the U. S. National Herbarium, no. 690287, collected in the vicinity of 
Cloudcroft, near the summit of the Sacramento Mountains, altitude about 2620 
meters, August 15, 1901, by E. O. Wooton. 
ADDITIONAL SPECIMENS EXAMINED: Cloudcroft, August 24, 1901, Wooton; 
James Canyon, August 11, 1899, Wooton. 
This is as nearly related to S. pudicus as to any species, but its foliage is 
very different. In that species the leaves are linear to oblanceolate, tapering 
to the base, and nearly entire. In S. sacramentanus the leaves vary from 
cordate-ovate to oblong-lanceolate, are coarsely serrate, and are mostly truncate 
to abruptly contracted at the base. The general appearance of the two is so 
unlike that at first glance one would not suspect the relationship between them.
