The list has three species of the genus Clematis, the two

 Anemones, A. multifida DC. is omitted and A. cylindrica 

 Gray, a species overlooked by Bessey, is given. The two 

 Hepaticas and four Thalictrums given by Bessey are in- 

 cluded. Of the genus Ranunculus there appear the same 

 species as in Bessey 's list with the addition of R. recurvatus 

 Poir., giving the locality Davenport, and R. aquatilis L. 

 var. stagnalis DC, which variety is further mentioned in 

 the appendix, p. 37 . Myosurus minimus L,. and Hydrastis 

 canadensis L. are for the first time mentioned in Iowa 

 literature, the locality for the former is given as Davenport 

 and for the latter, Lee county. Isopyrum bitcrnatum T.
