subtended by very minute subulate bracts. More northern prairie 

 species. 



3. EuTHAMIA MEDIA. 



3. Leaves linear-attenuate, acuminate, 2-5 mm. wide, strongly 

 punctate on both faces, more or less viscid; involucre 5-6 mm. 

 high, subturbinate; bracts of the involucre oblong-linear or oblong, 

 blunt, firm, very glutinous; pedicels subtended by linear bracts. 

 Western and Southern prairie species. 



4. EUTHAMIA GYMNOSPERMOIDES. 



i. Euthamia hirtella Greene, Leaflets, Bot. Obs. and Crit. 

 1 : 180 1906. 



If I have interpreted Dr. Greene's species rightly, this is a tall, 

 simple-stemmed plant, branching at the top, 7.5-15 dm. tall, with 

 much the aspect of Leptilon canadense; leaves spreading, 7.5-12.5 

 cm. long, S- 1 4mm. wide, 3-5-ribbed, at least the midrib conspicuous, 

 the lateral very faint, sparsely to densely short-hairy on both faces. 

 Appears to be a marsh or swamp species. Those who prefer to use 

 Solidago for the name of these spe:ies may use Solidago htrTELLA 

 (Greene) Bush, n. comb. The range of this species is from Massa- 

 chusetts^) to Wisconsin, south to Kentucky and Tennessee. 1 



'I have concluded with Dr. Greene that Euthamia graminifoua 

 (L.) Nuttall, to which were formerly referred all the species of Euthamia 

 in North America except EE. occidentals, tenuiFolia and lEptocephala, 

 is a species of the northeastern States and Canada, and I have not seen any 

 specimens from the interior that I could refer to it. 



Britton in the Illustrated Flora rays of Euthamia graminifoua, " New 

 Brunswick to Saskatchewan, Alberta, Florida, Nebraska and Wyoming; 

 heads 20-30 flowered." I have not seen any specimens from Saskatchewan, 

 Alberta, Florida, Nebraska or Wyoming that had heads with so many 

 Bowers. 



Fernald in Gray's New Manual says of Solidago graminifolia, "East 

 Quebec to Saskatchewan, New Jersey, Illinois, Missouri and North Carolina; 

 heads 20-30 flowered." I have not seen any specimens from Saskatchewan, 

 Illinois, Missouri, or North Carolina, that had heads with so many flowers. 



Small in his flora says of Euthamia GRAMINIFOLIA, "Nova Scotia to 

 the Northwest Territory, Florida and Kansas; ra^-flowers 12-30." I have 

 not seen any specimens from the Northwest Territory, Florida or Kansas 

 that had heads with so many ray-flowers. 



Gray in the Flora of North America says of Solidago lanceolata, " Canada 

 to Georgia, northwest to Montana." I have not seen any specimens from 

 Georgia or Montana that I thought wen- this species.
