WOOTON AND STANDLEY—-NEW PLANTS FROM NEW MEXICO, 187 
rigid, sessile, oblong or oblong-ovate, 20 to 45 mm. long, obtuse or acutish, sub- 
cordate or clasping, conspicuously veined, coarsely spinulose-serrate, puberulent ; 
involucres about 1 cm. high, the bracts linear-lanceolate to oblanceolate, glan- 
dular, spinulose-tipped; rays rather broad, 8 mm. long; achenes 3 to 4 mm. 
long; papus tawny, 6 mm. long. 
Type in the U. S. National Herbarium, no. 690258, collected at Baldy, August 
14, 1910, by E. O. Wooton. The plant was first collected at Raton, August 22, 
1897, by Dr. C. L. Herrick (no. 762). Specimens not yet in flower were gath- 
ered on the sides of Goat Mountain at Raton, June 22, 1911, by Paul C. Standley 
(no. 6330). The plants are very abundant about Raton, growing in the can- 
yons on the sides of the mountains in oak chaparral. 
EXPLANATION OF PLATE 50.—Part of type specimen. Slightly less than natural size. 
Aster hydrophilus Greene, sp. nov. in herb. 
Perennial or biennial; stems simple, bright green, 80 to 40 cm. high, stout, 
glabrous up to the inflorescence; cauline leaves linear or very narrowly linear- 
lanceolate, 6 cm. long or less, 3 to 4 mm. wide, attenuate, acute, sessile by a

Type in the U. S, National Herbarium, no. 498171, collected along the edge 
of Berendo Creek at the south end of the Black Range, Sierra County, Septem- 
ber 22, 1904, by O. B. Metcalfe (no. 1393). Altitude 1,500 meters,

below or simple; leaves thick and rather fleshy, green, glabrous, few and incon- 
spicuous, linear or linear-lanceolate, 8 cm. long or less, acute; inflorescence

ADDITIONAL SPECIMENS EXAMINED: Near Lake Arthur, August 1, 1905, Wooton; 
Roswell, August 28, 1902, Cockerell. 
In general appearance the plants resemble A. paucifiorus, but that is usually 
a smaller plant and has strongly glandular peduncles and involucres. 
Machaeranthera amplifolia Wooton & Standley, sp. nov. 
Biennial or perhaps perennial, 70 em. high or lower; stems slender, sparingly 
paniculate-branched above, the branches ascending, almost glabrous below,

tipped, but the stems scarcely viscid; leaves bright green, the basal ones broadly 
spatulate, 40 mm. long and 25 mm. wide or less, broadly obtuse, narrowed at 
the base to a long, slender, winged petiole, the petiole as well as the base of
