196 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM. 
margins spine-tipped, the blades glabrous beneath, above sparingly white- 
villous, lanate along the midrib; inflorescence of rather few heads, these race- 
mose in age, crowded when young, on short, stout peduncles or sometimes ses- 
sile, subtended by reduced, very spiny leaves; heads campanulate, 3 cm. high 
and as broad or smaller; bracts linear, none of them with dilated tips, the 
outer arachnoid on the backs and’ margins, tipped with a long, slender spine and 
usually bearing 2 or more slender lateral spines just below the tip; inner bracts 
lanceolate, thick and firm, scaberulous, with slender, flat, weak tips; corollas 
greenish yellow; achenes oblong-obovate, dark brown, glabrous and shining.

A common species in the higher mountains of New Mexico, occurring chiefly 
in the Transition Zone, although frequently extending farther up. It grows 
usually in swamps or marshes along the edges of mountain streams, sometimes 
in shaded thickets, frequently in open meadows. It is a tall, coarse plant, with 
pale yellowish stems and foliage. Commonly this has passed as Carduus parryi. 
Apparently no one has ever questioned this determination, yet examination of 
herbarium material reveals the fact that true parryi does not occur in New 
Mexico. That species differs from ours in its small heads, more spiny leaves, 
and the conspicuously dilated bracts. 
Carduus vinaceus Wooton & Standley, sp. nov. 
Tall biennial, 1 to 2 meters high, with very numerous ascending branches; 
stems brownish purple, striate, slender, glabrous; basal leaves glabrous, green, 
30 to 50 cm. long, 20 cm. wide or less, elliptic-oblong in outline, pinnatifid 
nearly to the midrib, the segments overlapping, laciniately lobed, the lobes 
oblong-lanceolate, acute, the teeth tipped with short, slender, yellowish spines; 
heads very numerous, naked, campanulate; bracts in numerous series, narrowly 
lanceolate, with long, flat, weak, spreading tips, deep reddish purple through- 
out, glabrous on the back, scarcely keeled, ciliate or puberulent on the margins, 
tipped with short, slender, yellowish spines; inner bracts with long, slender, 
twisted tips; whole head 5 cm, in diameter and 4 em, high or smaller; corolla 
lobes long and narrow, purplish; achenes obovate, brown, glabrous, with tawny, 
plumose pappus 15 to 20 mm. long.

No other North American species of which we have seen either specimens or 
description is at all like this in the form of the involucre. Some of the Mexican 
species suggest our plant but not very closely. When growing it is a handsome 
large plant with very numerous, purplish heads and dark stems, these contrast- 
ing with its glabrous, bright green foliage.
