agreed about the characters which constitute a species in the 

 Rubi. 



RuBUs, L. Bramble. — Stems variable, but mostly shrubby, 

 rarely herbaceous. Leaves compound, variable. Flowers ter- 

 minal, panicled or corymljose. Calyx five-parted ; segments 

 concave, pointed. Petals five, obovate. Stamens indefinite. 

 Ovaries aggregate, with a nearly terminal style to each, placed 

 on a spongy, conical receptacle. Fruit an agglomeration of one- 

 seeded, juicy drupes. Seeds hard, wrinkled, pitted. 



These plants are characterized by the long, usually arching, 

 angular or round, prickly stems, which are of two years' dura- 

 tion (but some exceed this period) ; also by their acid, pulpy 

 fruit, which is mostly black, but sometimes crimson or yellowish- 

 white. They grow in temperate regions, and rarely between the 

 tropics. 



Note. — The range or area of the various so-called species of 

 this genus, is quoted from the third volume of ' Cybele Brit.,' 

 p. 337 : it is supplied by Mr. Babington.
