WOOTON AND STANDLEY—NEW PLANTS FROM NEW MExIco. 195 
Carduus gilensis Wooton & Standley, sp. nov. 
Tall, sparingly branched biennial with slender, striate, villous stems; basal 
leaves oblanceolate, about 40 cm. long, acute, conspicuously lobed, the lobes 
dentate, the few teeth tipped with slender spines, glabrous on the lower surfaces, 
puberulent above; upper cauline leaves oblong or triangular-lanceolate, acute, 
clasping at the base, shallowly lobed, the lobes and their principal teeth with 
numerous long, slender, salient spines; heads usually solitary at the ends of 
the branches, campanulate, about 3 cm. broad or more and of the same height, 
subtended by many narrowly linear-lanceolate, spiny, bract-like leaves; outer 
bracts foliaceous, linear-lanceolate, with elongated tips, often arachnoid on the 
margins, pectinate with very numerous spiny teeth; inner bracts broader, 
scaberulous, little or not at all dilated at the tips and laciniate; corollas green- 
ish yellow. 
Type in the U. 8. National Herbarium, no. 495440, collected in the Mogollon 
Mountains on the West Fork of the Rio Gila, Socorro County, altitude 2250 
meters, August 4, 1903, by O. B. Metcalfe (no. 377). 
This, like O. inornatus, was determined as CO. parryi. It is of that group, but 
is distinguished by its large, mostly solitary heads, as well as by its unusually 
large and thin leaves, and the very numerous foliaceous bracts. 
Carduus inornatus Wooton & Standley, sp. nov. 
Tall biennial about 1 meter high with a stout stem, this simple below, above 
with a few ascending branches; stems striate, sparingly arachnoid, densely so 
on the younger parts, nearly glabrous in age; basal leaves not seen; lower 
cauline leaves linear-lanceolate, 10 to 18 cm. long, 17 mm. wide or less, with 
few remote, triangular, spine-tipped teeth, the margins beset with fine spines, 
glabrous beneath except on the midvein, sparingly villous there as well as on 
the upper surface with long, weak, white hairs; upper cauline leaves lanceolate 
or oblong, acute or attenuate, sessile and clasping at the base, the auricles 
rounded, the margins irregular and bearing numerous slender, yellow spines; 
heads few, occasionally solitary at the ends of the branches but usually in 
clusters of about 3, pedunculate, campanulate, 25 mm. long and 20 mm. broad 
or smaller, subtended by numerous spiny, reduced, bract-like leaves; bracts of 
the involucre in several series, successively shorter outward, the outer linear- 
lanceolate with long-attenuate tips, mostly glabrous on the back, rarely slightly 
arachnoid, spine-tipped, the margins bearing many weak, yellow spines; inner 
bracts broader, scaberulous, most of them abruptly dilated at the tips into a 
lanceolate or oval, often laciniate, spine-tipped portion; corollas yellow ; achenes 
obovate, compressed, brownish, 4 to 5 mm. long, the pappus about 10 mm. long. 
Type in the U. S. National Herbarium, no 5610138, collected in the Sacramento 
Mountains near Cloudcroft, August 24, 1901, by E. O. Wooton. 
Originally this collection was determined as C. parryi, and it is nearer to 
that than to any other species. It differs in having fewer heads and slightly if 
at all arachnoid bracts with pectinately spiny margins and less dilated tips. 
The leaves, too, are not nearly as spiny as in that species, and only the inner- 
most bracts have dilated tips, while in C. parryi almost all have them. 
Carduus pallidus Wooton & Standley, sp. nov. 
Tall biennial, 1 to 2 meters high, with simple, very leafy stems sparingly 
branched about the inflorescence; stems stout, arachnoid above, becoming gla- 
brate below, striate; lower cauline leaves lanceolate, acute, uttenuate to the 
base, irregularly serrate-dentate, the teeth tipped with short, weak spines; 
upper cauline leaves narrowly oblong to triangular-lanceolate, clasping at the 
base, with rounded auricles, acute irregularly dentate or shallowly lobed, the
