108 PITTONIA. 
at summit few and long-pedunculate heads: leaves of spatu- 
late-oblanceolate outline, obtuse or acutish, saliently but not 
runcinately toothed: peduncles and involucres glandular- 
hispid: slender-fusiform achenes tapering; pappus fine and 
fragile. 
Meadows along the Humboldt River at Deeth and else- 
where in eastern Nevada, thence northward to southern 
Idaho. Related to C. runcinata and platyphylla. 
CREPIS LANCIFOLIA. Naked and scapiform stems and tufts 
of radical leaves several from a perennial root: herbage 
glabrous throughout even to the involucres: leaves 5 to 8 
inches long, narrowly oblanceolate, attenuate-acute, entire, 
with narrow winged petioles: rather large and showy heads 
forming a somewhat close cymose terminal cluster: bracts 
of the involucre oblong-lanceolate, very thin and glabrous 
except at the very tip which is pubescent: achenes not 
known. 
Moist meadows below Marshall Pass, Colorado, 4 Sept. 
1896. Also of the group to which C. runcinata belongs, but 
with marked characters of leaf and involucre, and a peculiar 
mode of growth, the root being surmounted by a short 
branching caudex. : 
ALLOCARYA NITENS. Annual, prostrate, very diffusely 
branched, the slender branches a foot lon g or more, racemose 
and leafy or leafy-bracted almost throughout, the foliage 
and especially the calyx stri gose-hispidulous; corolla minute: 
nutlets 1 line long, ovate, acuminate, obtusely but promi 
nently carinate ventrally down to the narrow supra-basa 
scar, the back wholly devoid of either rugosities or murica- 
tion, but marked lengthwise by a low broad median eleva- 
tion, the whole surface on all sides otherwise smooth and 
vitreous-shining. 
Dry beds of spring pools in meadows of Pine Creek, Ne 
vada, 20 July, 1896. A very strongly marked species by its 
smooth and polished nutlets.
