and Phegopteris are not illustrated; the figures of Ch. vestita 

 and W. glabella are very indifferent, the latter particularly so. 



The following extracts from the preface are of interest : — 



" This work is designed as a compendious Flora of the Northern 

 portion of the United States, for the use of students and of 

 practical botanists. 



" The first edition (published in 1848) was hastily prepared to 

 supply a pressing want. Its plan, having been generally approved, 

 has not been altered, although the work has been to a great extent 

 twice rewritten, and the geographical range extended. The second 

 edition, much altered, appeared in 1856. The third and fourth 

 were merely revised upon the stereotype plates, and some pages 

 added, especially to the latter. 



" The Garden Botany, an Introduction to a Knowledge of the 

 Common Cultivated Plants, which was prefixed to this fourth 

 edition in 1863, is excluded from the present edition, and is to 

 be incorporated into a simpler and more elementary work, but of

 that the Lichen es, if not all the other orders of the Lower 

 Cryptogamia, may be added to this supplementary volume, so 

 that our students may extend their studies into these more 

 recondite and difficult departments of Botany.

" There is abundant reason, I doubt not, for me to renew the 

 request that those who use this book will kindly furnish informa- 

 tion of all corrections or additions that may appear to be necessary, 

 so that it may be more accurate and complete hereafter, and 

 maintain the high character which it has earned. 



" Geographical Limitation, Distribution, etc. As is stated on the 

 title-page, this work is intended to comprise the plants which grow 

 spontaneously in the United States, north of North Carolina and 

 Tennessee, and east of the Mississippi. A Flora of the whole 

 national domain, upon a similar plan (the issue of which I may
