GENUS EUTHAMIA IN MISSOURI 1 67 



Illinois and Missouri, southward, according to Greene, 1. c. 



First collected by Engelmann. 



I have concluded that the prairie plant of Ohio, Indiana, 

 Illinois, Missouri, Iowa and Michigan belongs to Dr. Greene's 

 species, and I have been unable to distinguish Fernald's Solidago 

 Moseleyi from it. If we are to accept Dr. Greene's E. gymnosper- 

 moides which has been generally included in E. graminifolia, 

 E. TEnuifolia and E. lEpTocephala, as a valid species, E. minor 

 Greene, and E. Floribunda Greene (the last having been accepted 

 by Fernald in .Gray's New Manual as a species in Solidago, may be 

 known as Solidago floribunda (Greene) Bush, n. comb., if 

 these species are finally placed in Solidago), it seems to me very 

 reasonable to accept this species, and several others of Dr. Greene's, 

 than try to keep it in E. graminifolia, from which it differs in 

 several important characters, notably the fewer-flowered heads. 1 



If the species of Euthamia are to be included in Solidago, 

 this species will take the name Solidago media (Greene) Bush, 

 n. comb. 2 



1 Euthamia camporum Greene, of the far West and Northwest, seems 

 distinct from E- media in the firm, almost coriaceous leaves, which are 

 strongly punctate on both faces. If this species is to be referred to^Solidago, 

 it should bear the name Solidago camporum (Greene) Bush, n. comb. 

 Amongst the many specimens of this species examined, I refer the following: 



Kansas: 

 Riley County, Norton, 231, September 13, 1895, Herb. No. 75294. 



2 I have not been able to see many specimens of Euthamia remota 

 Greene, but the few I have seen were sufficient to cause me to believe that 

 this species is very distinct from E- TEnuifolia, to which it has been re- 

 ferred by Britton in Illustrated Flora, and perhaps by Fernald in Gray's 

 New Manual, and Small in his Flora. This belongs to the E. TEnuifolia 

 group, with upper leaves 1 -ribbed, the lower often with a pair of indistinct 

 lateral nerves, but the leaves are much longer and wider, do not droop, and 

 the involucre is cylindrical in shape, and attenuate at the base. In aspect 

 it resembles E. media on the one hand, and on the other E- TEnuifolia, 

 but is remote from both of these species'. Like E. hirtella, this species is 

 also a lake region species. The thickish, oblong-linear bracts, in several 

 series, with thick green tips, alone separates this species from E- tennifolia. 



Of the few sheets of specimens examined, I feel certain of the following: 

 Illinois: 



Chicago, Glatfelter, August 20, 1893, Herb. No. 75312. 

 Indiana: 



Drue Park, Chase 278, September 19, 1898, U. I. Herb.; 

 Dune Park, Greenman, 2692, September 11, 1908, Herb. No. 

 740564;
