list being brought down to January, 1891, and considerable in- 
formation added to that already printed in the Journal. While the 
list is of not quite the importance to American botanists that it is _ 
to English there is so much matter of direct application to our 
own Botany that it really ought to be in the hands ofall. We 
are so much interested in the success of this project that we will 
receive subscriptions to the work at $1 per copy, payments to be 
made when the book is received. IN, 1k By

This is one of the most carefully prepared and valuable local 
floras ever published, giving the results of the author’s studies in 
the vicinity of Ames during the past seven years.. Localities for 
the rarer species are given in detail. The principle of using the 
earliest specific name has been closely adhered to, the original 
author being cited in parenthesis. Many critical and very useful 
notes on nomenclature and determination of species are given. 
Several old names are here first taken up, as follows: Anemone 
patens, L. var. hirsutissima (Pursh), for var. Nuttalliana, A. 
Gray; Anemone Hepatica, L. var acuta (Pursh), for Hepatica 
acutiloba, DC.; Viola palmata, L. var. obligua (Hill), for var.
