156 ' — PITTONIA. 
with a few leafy bracts at base, somewhat villous-hirsute 
at the gradually thickened summit: bracts of the involucre 
linear, acuminate, rather densely hirsute below, the acu- 
minate tips naked and of a dark purple: rays numerous 
and slender, decidedly shorter than in E. compositus, pinkish 
or flesh-color: pappus rather copious and firm, of a distinct 
purplish red. 
Sandy river bank at Fort Selkirk in the Yukon Valley, 
28 June, 1899, M. W. Gorman. A most distinct new Eri- 
geron, remarkable for the vivid color of the pappus. No 
more interesting plant has come to us from the far North- 
west in recent years. It is therefore unfortunate that but a 
single specimen was collected ; though that is a very good 
one. 
"ERIGERON Gormant. Near E. compositus, the herbage of 
a much more vivid green, minutely and densely glandular 
and viscid, scarcely pubescent, but with a scattered and 
almost hispid ciliation on the pitioles of the short and almost 
erect leaves ; earliest foliage merely 3-cleft or lobed and the 
lobes little divergent, oblong; later leaves with the lateral 
lobes, and sometimes the terminal one, 3-lobed: numerous 
scapes about 4 inches high, far surpassing the leaves, linear- 
bracted below: involucres only sparsely hirsute: rays very 
numerous, rather slender, flesh-color. 
Dry sandy soil at Fort Selkirk on the Yukon River, 28 
June, 1899, M. W. Gorman. 
" EvcEPHALUS FoRMOsus. Habit of E. glaucus but smaller 
and less branching, equally pale and glaucous, the leaves 
thinner, not reticulate, pungently mucronate, the margin 
scabrous-denticulate under a lens; branches of the corym- 
bose panicle pubescent: involucres broad and subcam- 
panulate, their bracts in 4 series, very broad and obtuse, 
cuspidately or mucronately pointed, minutely woolly- 
ciliolate, deeply purple-tinged: rays very showy, about
