40 PITTONIA. 
Alpine on Mt. Shasta, California; cellected by Dr. Mer- 
riam, 3 Aug. 1898. Species of the typical group of the 
genus; but all its immediate relatives are large plants, and 
of lower altitudes. 
ANTENNARIA CONFINIS. Stems tufted, suffrutescent, as- 
cending, very leafy, 6 to 10 inches high including the spar- 
ingly bracted scapiform peduncles: leaves spatulate-oblong, 
obtusish, mucronulate, about 4 inch long, 1-nerved, densely 
silky-tomentose on both faces: heads 5 to 9, subsessile and 
glomerate at summit of the bracted peduncle: involucre 
small and rather short, the bracts with brownish-yellowish 
very obtuse scarious tips from obovate in the outer series to 
oblong in the inner: bristles of the pappus short and rather 
rigid: male plant unknown. 
Species based on specimens obtained in the Santa Cata- 
lina Mountains, Arizona, in June, 1880, by Mr. J. G. Lem- 
mon. Itisof the group to which belong A. media of the 
Sierra Nevada, and A. umbrinella of the northern Rocky 
Mountains; but is distinetly suffrutescent, the stolon-like 
branches of the early part of the season remaining proper 
branches, not rooting. The involucres differ from those of 
A. umbrinella in that the scarious tips of the bracts are firmer 
in texture, and of only a brownish-creamy color.
