56 PITTONIA. 
about 4, those of the disk*about 6; achenes with only a few 
hairs; pappus of about ten pales, the greater part of them 
somewhat lanceolate, or oblanceolate, the others narrower 
and shorter. 
Foothills of the mountains back of Silver City, New 
Mexico, collected by the writer Sept. 30, 1880. 
G. FASCICULATA. Size of the last, but less slender, the 
stem and leaves still more sparingly scaberulous, somewhat 
granular and quite viscid, the leaves few and widely spread- 
ing, the axils bearing short very leafy branchlets mostly 
sterile, but some monocephalous: inflorescence somewhat di- 
chotomously cymose-panicled: involucres oblong-clavate, 
2 lines high, their bracts in about 4 series, all except the 
broad innermost ones with erect and stout green-herbaceous 
tips: flowers of disk and ray about five each; achenes some- 
what silky, and pappus of lanceolate paleze only fewer in 
the ray, nearly as long as those of the disk. 
Collected at Grand Junction, Colorado, 26 Aug., 1896. 
The flowers are all of a notably pale color for this genus. 
G. yUNCEA. Very slender densely tufted stems erect from 
a much branched woody base, destitute of leaves at flower- 
ing time, bearing above the middle numerous fastigiate 
almost filiform reedy branchlets each ending in a glomerule 
of about 3 sessile heads, the branchlets sharply angular and 
hirtellous-seabrous, clothed with scattered short and spread- 
ing leafy bracts: involucres oblong-obovoid, less than 2 lines 
high, their narrow bracts with acutish green tips: flowers of 
ray and disk each 4 or 5: pappus-palee lanceolate, acute. 
Obtained near Gray, New Mexico, in August, 1898, by 
Miss Skehan ; and also collected on Eagle Chief Creek, Okla- 
homa, 12 Oct., 1896, by L. F. Ward, whose specimens are in 
the U. S. Herbarium. The species of quite peculiar aspect, 
the leaves having mostly fallen at flowering time, the bushy 
tufts of naked reedy stems bearing only a few bracts on the 
filiform twigs of the flat-topped inflorescence,
