The Genus Euthamia in Missouri.

BY BENJAMIN FRANKLIN BUSH. 



JUN 1 4 wo 



Having had occasion last January to examine some specimens 

 collected by Mr. Ralph Hoffman about Kansas City in Jackson 

 County, Missouri, my attention was directed to some specimens 

 of Euthamia, which upon a casual inspection might pass for E. 

 graminifolia (I,.) Nuttall, a species commonly supposed to occur 

 in this locality, but which upon a closer examination seemed to 

 differ from the description of that species in several important 

 particulars. 



No other species of Euthamia being known for this region, 

 and only one other, E. EEptocephala (T. &G.) Greene, a low-land 

 species of Arkansas and Louisiana, which extends up the Mississippi 

 Valley to the low, flat, quaternary formation of the southeastern 

 part of the State, it was interesting to note this new accession to 

 the Flora of a region thought to be well covered by a descriptive 

 Manual. 



Having in mind always the bare possibility that every strange 

 plant of this region may be an undescribed species, I wrote to Dr. 

 George T. Moore of the Missouri Botanical Garden to kindly loan 

 me volume 5 of Dr. Greene's Pittonia, in which E. gvmnospermoides 

 Greene, a species of the high prairies of Kansas and Nebraska, 

 and most probably the species in hand, was described, and my 

 astonishment may be imagined when I saw that Dr. Greene had 

 established the species on plants collected by me in the Indian 

 Territory in 1894, and that I had left my native county where I 

 had collected for many years, to go down to the Indian Territory 

 to collect this most interesting and distinct Euthamia, when it 

 was common on the prairies of the County where I lived.
