In this arrangement the author divides the genus, as rec- 

 ognized by him, into two sections, viz.: Euvitis, Planchon, 

 and Puncticulosis, Munson. The first section is divided into 



r 



seven series, called respectively Ripariae, Occidentales, CoriacciTJ, 

 Labruscre, iEsti vales, Cordifoliae and Cinerascentes. Section 

 two is represented by the eighth series only, denominated Mus- 

 cadiniae. Twenty-five species are recognized. The following are 

 as new: Vitis DoaniiVia, V. Arizo}iica, var. glabra, V, Girdiana, 

 V. Lincecumii, var. glanca, V. Si^npsoni^ V, Virginiana, V\ cinerea,

This is the most extensive contribution towards the illustra- 

 tion and description of our native grasses hitherto issued, and is 

 an exceedingly valuable contribution to botanical science, as well 

 as to that of agriculture. The drawings, made chiefly by Mr. 

 Wm. R. Scholl, are accurate and artistic, most of the species be- 

 ing given natural size and accompanied by enlargements of the 

 flowers. They are reproduced by lithography. From an in- 

 troductory note we learn that this constitutes one-half of the first
