70 PITTONIA. 
spike before expansion of the corollas is only round-oval, 
and appears as if it were a mere cluster of long almost fili- 
form plumose bracts. 
SOLIDAGO PRUINOSA. Erect, 3 feet high or more, very leafy 
up to the dense short pyramidal panicle of short spreading 
or slightly recurved abruptly ending and obtuse racemes of 
rather large heads: leaves ascending, 2 inches long, elliptic- 
lanceolate, acute or acuminate, slightly but evenly serrate 
from near the base to near the apex, distinctly 3-nerved and 
canescent or almost hoary on both faces with a dense rather 
soft puberulence or pubescence: pedicels and branches of the 
inflorescence almost tomentulose: bracts of the more than 
middle-sized involucre in about 3 series, the short outer ones 
subulate-linear, the inner long ones also visibly narrowed _ 
from base to apex but obtusish ; flowers apparently light- 
yellow. 
Collected at Moose Jaw, Assiniboia, 13 Aug., 1895, by Mr. 
John Macoun, and numbered 10,893 and 10,894 in the Cana- 
dian Survey Herbarium. An uncommonly good species of 
the section to which S. Canadensis belongs, but with the in- 
dument of such species as S. Californica and S. nana, no 
approach to which is made in any eastern or southern forms 
of the S. Canadensis group. 
EucEPHALUS Macounn. "Tall and amply leafy but rather 
slender, sparsely but rather roughly puberulent: lower 
leaves oblong-lanceolate, 3 inches long, the upper oblong, 
sessile by a broad half-elasping base, all acute and remotely 
but very sharply serrate: heads few and corymbose, about 
i inch high; involucres broadly turbinate, their bracts in 
about 4 series, all lanceolate, very acute, purplish and stiffly 
ciliolate marginally, but pubescent on the back and very 
herbaceous for the genus: rays 10 to 15, narrow, violet: 
achenes pubescent; pappus-bristles rather slender and soft, 
but the longer ones dilated upwards.
