but differs in the more yellowish-green herbage, the whiter stems, 

 the narrower, more erect, thick, i -nerved instead of 3 -nerved leaves, 

 the finer pubescence, and the involucres, which are narrower and 

 with different bracts. In C. piibcmlns \\\& inner bracts are linear or 

 linear-lanceolate and acute. The young achenes are only slightly 

 strigose, in which respect it approaches C. Bakcriz.x\^ C. Vaseyi.

Solidago missouriensis Nutt. Jour. Acad. 

 Phila. 7 : 32. 1834 



Solidago Toliideana A. Gray, Syn. Fl. i' : 151. 1884. 



Dr. Gray in the original publication of S. Tobiiicaiia adds the 

 following note : " Has been taken for a form of 5". missojtriensis 

 var. montana;'' but he overlooked the fact that it was identi- 

 cal with the original .S". nnssonriensis. He might have been led 

 astray by Nuttall himself, who later included in S. unssonriensis the 

 common plant of the upper Missouri Basin with recurved secund 

 branches. That the latter is not the original 5". missouriensis may 

 be seen from Nuttall's diagnosis, of which I here give a copy : 



"55 Solidago * vnssonriciisis. 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 5. Tolmicaua but not with the plant de- 

 scribed by Gray as wS. missouriensis. 



The original Solidago vnssoiiriensis 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. Tolmieana 

 in the Gray Herbarium. The plant described by Gray as ^. vns- 

 soiiriensis 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-
