WOOTON AND STANDLEY—NEW PLANTS FROM NEW MEXIco. 177 
surfaces, glandular-dotted beneath, all on slender petioles 7 mm. long or less; 
inflorescence of few, clustered heads terminating long, naked branches; heads 
campanulate, 7 mm. high, on short, glandular or puberulent peduncles; bracts 
linear, appressed, attenuate, puberulent, striate: flowers but little exceeding 
the bracts; achenes 3 mm. Jong, 5-angled, glabrous; pappus a short, obtusely 
toothed, glabrous crown. 
Type in the U. S. National Herbarium, no, 232780, collected in Guadalupe 
Canyon, Sonora, August 27, 1893, by E. C. Merton (no. 2031). Also on Cajon 
Creek in Chihuahua along the New Mexico line, August 16, 1892, Mearns 700. 
Guadalupe Canyon extends into New Mexico, and doubtless the plant occurs on 
the north as well as on the south side of the boundary. 
Doctor Gray reported this plant from this same region as Ageratum corym- 
bosum Zuce., but the northern plant is very unlike true corymbosa, which occurs 
much farther south. It differs especially in the form of the leaves and in the 
pubescence and inflorescence. 
Kuhnia chlorolepis Wooton & Standley, sp. nov. 
Perennial with numerous stems from a thick, woody root; stems slender, 
erect, 30 to 50 cm. high, simple up to the inflorescence, there abundantly 
branched, densely puberulent; upper leaves linear, the lower lanceolate or 
Jance-linear, all obtuse, densely puberulent, sessile, 3-nerved, glandular-dotted 
on the lower surface; heads numerous, on long, slender peduncles, large, 15 
mm. high; bracts firm, green tinged with purple, linear-oblong, broad, the 
outer short and acute, the inner obtuse or acuminate, finely pubescent, conspicu- 
ously striate, in several series, the outer ones gradually and successively 
shorter; corolla lobes oblong-lanceolate, rather long; achenes pubescent, 6 mm. 
long, finely striate; pappus 6 mm. long, whitish, copper colored at the base. 
Type in the U.S. National Herbarium, no. 560399, collected at Mangas Springs, 
June 2, 1903, by O. B. Metcalfe (no. 104). 
ADDITIONAL SPECIMENS EXAMINED: Gila River bottom near Cliff, alt. 1,350 
meters, 1903, Metcalfe 152; 1851-2, Wright 1394 and 1182 (in part); Alamo 
Viejo, 1892, Mearns 188; Mexican Boundary Survey 458 (in part). 
This is most nearly related, perhaps, to A. gooddingii A. Nels., but that has° 
smaller hends and densely glandular bracts. In that species, too, the bracts 
are much thinner and not green. 
Coleosanthus chenopodinus Greene, sp. nov. in herb. 
Small, much-branched shrub; stems stout, with exfoliating bark, puberulent 
below, glandular above, densely branched ; leaves small, ovate or lanceolate, 35 
mm. long or less, rather thick and succulent, glabrous or nearly so, acute, 
rounded or cuneate at the base, somewhat serrate; heads paniculate, large, 
about 12 mm. long, on slender, leafy, densely viscid peduncles 2 to 4 cm. long; 
outer bracts often foliaceous, lanceolate, the others lanceolate to oblong-linear, 
conspicuously nerved, glandular-viscid, acute, or the inner obtuse; achenes 
faintly strigose. 
Type in the U. S. National Herbarium, no. 495728, collected in the Gila River 
bottom near Cliff, Grant County, September 22, 1903, by O. B. Metealfe (no. 
776). Altitude 1,850 meters. 
A peculiar species, somewhat related to C. floribundus, but with very long 
peduncles, larger heads, and peculiarly succulent leaves. 
Coleosanthus venosus Wooton & Standley, sp. nov. 
Low perennial, 50 cm. high or less, with sev eral stems from a woody root; 
stems slender, simple below, sparingly branched above, cinereous-puberulent ; 
leaves narrowly oblong to linear, obtuse, sessile, entire or obscurely serrate,
