rally now termed. Whoever examines into the 

 subject, will however soon find numerous brambles 

 not referable to either of these, and to draw more 

 general attention to the brambles, which they well 

 deserve, I here extract an analysis of the divisions of 

 the 'British Rubi, taken from Dr. STEELE'S Hand- 

 look of Field Botany. It will be thus seen that the 

 Fruticose Eubi are physiologically divisible into those 

 whose barren stems always root at the extremity and 

 those that never do so. If the student then examines 

 the barren stem of any bramble he meets with, he 

 will find it reducible to some one of the following 

 groups. To find the species he may either refer to 

 my descriptions given in STEELE'S Hand-Book, or to 

 the elaborate Synopsis of the Rubi, by Mr.
