Hab. Near Montreal. Mr. Cleghorn.^lYih is a very distinct species, of which I have also received 

 specimens from Dr. Schweinitz, with very long slender procuiubont shoots, densely covered with curved 

 aculei, which often extend likewise to the petioles and back of the costa of the leaflets. Peduncles slender 

 and flowers very small It is probably more common in the sonth than in the British Possessions. Tliis has 

 the most slender stem of any of the fruticose species, and almost unites the present groupe ^vith the folloiv iiig. 

 Sir James E. Smith has well remarked, in Rees* Cyclopaedia, that the name of this plant, and tho definition 

 of its leaves, "foliis ohovalibus" as given by Michaux, are decidedly incorrect: an oval leaf beiti"- of the 

 same breadth at each end. llubus ohovatus is unexceptionable, and expressive of the shape of the loaflt'ts.
