but differs in the more yellowish-green herbage, the whiter stems, 
the narrower, more erect, thick, 1-nerved instead of 3-nerved leaves, 
the finer pubescence, and the involucres, which are narrower and 
with different bracts. In C. puderulus the inner bracts are linear or 
linear-lanceolate and acute. The young achenes are only slightly 
strigose, in which respect it approaches C. Bakeri and C. Vasey.

Dr. Gray in the original publication of S. Zo/mieana adds the 
following note: ‘Has been taken for a form of S. mzssourtensis 
var. montana ;” but he overlooked the fact that it was identi- 
cal with the original S. mssouriensis, He might have been led 
astray by Nuttall himself, who later included in S. mssouriensis the 
common plant of the upper Missouri Basin with recurved secund 
branches. That the latter is not the original S. #zssourtensis may 
be seen from Nuttall’s diagnosis, of which I here give a copy: 
“55 SOLIDAGO * mssouriensis. Pumila, glabra, racemis erectis, 
foliis lineari-lanceolatis, acutis, inciso-subserrulatis, superioribus 
integris, panicula brevi laxa, floribus majusculis.”’ 
«Stem slender, smooth, leafy, about a foot or so high. Leaves 
scabrous at the margin. Panicle about three inches long, the 
branches slender, the flowers pedicellate, and brought together in 
a somewhat rhomboidal raceme. Rays as long as the calyx.” 
This agrees with S. Zo/mieana but not with the plant de- 
scribed by Gray as S. mzssourtensis. 
The original Solidago missouriensis was collected by Wyeth 
on the upper branches of the Missouri. There is a specimen of 
this collection in the Torrey Herbarium which agrees with the 
description and this matches very well the type of S. Zolmicana 
in the Gray Herbarium. The plant described by Gray as S. mis- 
souriensis is Characterized by its flat-topped or round-topped in- 
florescence with recurved-spreading, secund branches, in variance 
with Nuttall’s characterization: ‘‘racemis erectis,’” and ‘the flow-
