thus stniiiiosiis and Tacnidia intcf!;crrii)ia. On the prairies of 

 central Illinois it forms circular patches of considerable extent, 

 and in the Ozark region it is one of the commonest species in the 

 semi-mesophytic upland woods, growing as scattered individuals. 



Vibur)iu))i rufoto))ientosuin Small. On dry ledges and in fis- 

 sures of limestone cliffs, Jackson County. 



Serinia opposififo/ia (J^ixi.) Kuntz is abundant in Perry County, 

 Missouri, growing in sandy soil along the Mississippi River, and 

 also farther inland in dry upland woods. It has lately been col- 

 lected by Mr. E. S. G. Titus near Eldorado, Illinois, where it 

 grows in dry soil along a railroad, but in such surroundings that 

 it appears indigenous. 



Sitilias Caroliniana (Walt.) Raf. In wet, open places, Massac 

 County. 



Those areas in Virginia, Illinois and Missouri where the coastal 

 plain, with its austro-riparian flora reaches into the so-called 

 "Manual range" have always been a fertile field for collectors, 

 and from them many additional species have been added to the 

 " Manual flora." The work of B. F. Bush in the swamps of 

 southeastern Missouri has been of particular importance because 

 of the number of interesting species which he found there. Three 

 of these species, not previously reported from Illinois, were col- 

 lected in 1902 in the cypress swamps of Johnson and Massac 

 counties : Fraxinus profunda Bush, Sty rax Americaua Lam., 

 and I tea Virginica L. 



Koellia incafia (L.) Kuntze. The distribution of this species as 

 stated in the Illustrated Flora (3 : 114) or Britton's Manual 

 (802) does not include Illinois, the range given being Maine to 

 Ontario, Ohio and Florida. In southern Illinois it is abundant 

 in upland woods and abandoned clearings, where the white 

 canescent bracts make it very conspicuous. It has been col- 

 lected in eveiy county including and south of the Ozark uplift, 

 but its northern limit in the state is as yet undetermined. 



There are a number of other species in Illinois, whose range, 

 as given in the two works mentioned, does not include this state. 

 Among these may be mentioned the following: Cuui/a origanoidcs 

 (L.) Britton is common in the upland woods of the extreme south-
