than the original description permits. A form represented by no. 
4327 and some earlier collections, from the limestone ledges of the 
Laramie hills, is strongly matted and has the branches of the caudex 
enormously thickened and protected by the densely lanate leaf-bases. 
' Add to this its large root, broad green leaves, and the copious secre- 
tion of its punctate glands, and it might well stand as var. glandulosa. 
It is in this species that the salient character of the genus (4-nerved 
ligules) often fails ; 5-8 nerves are not infrequent. 
etraneuris Mancosensis, n. sp.— Tufted, with woody root and mul- 
ticipital caudex, the short.thickened crowns clothed with the expanded, 
membranous, lanate leaf-bases: leaves glabrous, 4-8" long, crowded 
on the crowns, linear or linear-oblanceolate, acute or cuspidate, rather 
minutely punctate: stems few to several, bearing a few (usually 2) dis- 
‘ant leaves, 2" in length (including the long monocephalous peduncle) : 
heads large, disk about 1™ high; involucre silky-lanate, the bracts in two 
a three tows, the inner oblong or somewhat expanded upwards by the 
— margins: palee of the pappus oblong-elliptic with an acu- 
mination as long as the body proper, equaling the disk corollas: 
ligules of the rays Is—rgm™ long, 6-8™ broad
