thick, conspicuously veined, canescent, 55 mm. long or less; heads few, 
racemose or narrowly paniculate, 10 to 12-flowered, 10 to 12 mm. high; 
peduncles slender, bearing 1 to 3 heads, 10 to 35 mm. long; bracts much im- 
bricated in several series, the outer orbicular to broadly oblong or ovate, 
obtuse or emarginate and mucronate, cinereous, the inner lanceolate, acute, 
ciliolate, all prominently striate; achenes equally striate, strigose, brown, 
with firm, white, scaberulous pappus.

The plant also occurs in southern Arizona and northern Chihuahua. In the 
Synoptical Flora it was listed as Brickellia oliganthes (Less.) A. Gray, but 
that name was applied originally to a plant from much farther south in Mexico. 
C. venosus differs in having much narrower, sessile, more pubescent leaves, as 
well as different inflorescence, bracts, and pubescence, Doctor Gray at various 
times remarked that the plant from New Mexico and Arizona was different 
from that of Mexico, but probably he had not sufficient Mexican material to 
warrant separation of the two. 
Grindelia neomexicana Wooton & Standley, sp. nov. 
Erect biennial or perennial, 50 cm. high or less; stems slender, sparingly 
branched from the base but abundantly branched above, the branches erect, 
leafy throughout, glabrous; cauline leaves narrowly oblong, or oblong-lanceolate, 
45 mm. long and 10 mm. wide or less, sessile, obtuse or acute, glabrous, sharply 
and evenly serrate, rarely entire; heads few, large, 15 mm. wide and 12 mm. 
high or smaller; rays numerous, showy, stiff, 15 mm. long, narrowly spatulate, 
obtuse; bracts many, elongated-linear, the outermost thick and green through- 
out, with lax, slightly spreading tips, the innermost wide, scarcely if at all 
viscid; heads subtended by 1 or 2 linear or Nnear-lanceolate, bract-like leaves; 
achenes light brown, faintly striate, the pappus smooth or sparingly and very 
faintly barbellate. 
Type in the U. 8. National Herbarium, no. 561099, collected in the mountains 
horth of Santa Rita, August 23, 1900, by E. O. Wooton. 
ADDITIONAL SPECIMENS EXAMINED: Mountains southeast of Patterson, August 
16, 1900, Wooton; G O S Ranch, 1911, Holzinger. 
We have seen no other New Mexican plant with involucral bracts like those 
of this species. They are unusually numerous, narrow, green, and only slightly 
spreading, none of them being recurved. 
Grindelia pinnatifida Wooton & Standley, sp. nov. 
Perennial or biennial, 30 to 45 em. high, with numerous stout stems from 
each root, these simple below but with numerous erect, slender, corymbose 
branches above; stems glabrous, striate, reddish above; lower leaves long-petio- 
late, laciniate-pinnatifid, the segments irregularly dentate, oblong, acutish ; upper 
leaves linear-oblong, laciniate-serrate, sessile by clasping bases, all glabrous or 
nearly so, conspicuously glandular-punctate; heads solitary at the ends of the 
branches, depressed-hemispheric, 15 to 17 mm. in diameter; bracts linear, with 
flat, green, slightly reflexed tips, densely viscid; immature achenes glabrous; 
pappus bristles smooth. 
Type in the U. S. National Herbarium, no. 685628, collected on open slopes 
about Chama, altitude about 2,400 meters, J uly 9, 1911, by Paul C. Standley (no. 
6606). 
The plant was very abundant about Chama, in the Transition Zone. It 
differs from all our other species in its evidently pinnatifid lower leaves. The
