species was introduced appears to be uncertain, but the popular 

 belief held throughout the Southern States, namely that the 

 plant was brought into that section during the Civil War period, 

 is erroneous, although it was doubtless then disseminated in 

 various sections where it had not been before observed. The 

 late Professor Porter found it thoroughly naturalized in middle 

 Georgia as early as 1846 while he was a resident of that state. 

 Its advent was probably unnoticed by the native residents on 

 account of the relative inconspicuousness of the plants, and how 

 long previous to 1846 the plant may have been established as a 

 member of our flora Professor Porter was not able to learn. 



During the first half of the last century the plant seems to 

 have spread slowly; however, during the second half, it advanced 

 north, northwest, and west, apparently establishing itself per- 

 manently wherever it gained a foothold. 



On account of local means of dispersal Lespedeza striata spread 

 westward more rapidy than northward The end of the last 

 century saw it established in Texas, Kansas, and Illinois, while it 

 was not until the beginning of the present century that it got a 

 firm hold in southern Pennsylvania. 



The geographical range for the species given in the several 

 floras within whose limits it occurs are too narrow, and should 

 read Pennsylvania to Kansas, Florida, and Texas.

Qanong's Teaching Botanist'*' 



Progressive teachers of botany already possess well worn copies 

 of the first edition of this pioneer contribution to the pedagogy 

 of their subject. The second edition, "rewritten almost through- 

 out", is brought abreast of the advance of the past decade in 

 botanical education, and will, no doubt, be even more warmly 

 welcomed than was the first edition. 



The title not only names the book, but designates the class of 

 readers to whom it is addressed, and to whom it will make its
