The species can be distinguished on sight from S. sicpinum Dun. 

 and its allies b}^ the acute points of the leaf-segments. 



Conspecific with this but with somewhat smaller and apparently 

 more deeply coloured flowers is a specimen {lloss Sf Hogers, 2062) 

 from Canada, Witwatersrand Div. This is a larger specimen and 

 shows more of the plant including the lower part of the stem, which 

 is fistular and nearly 5 mm. thick. Besides flowers, this specimen has 

 spheroidal, reddish berries measuring 10 mm. in diameter. The 

 leaves, although similar to those of the t^-pe, generally run smaller, 

 the upper ones being only 4 cm. in length or even less.
