 to be an introduced species,— the S. Ilusselliana, of the present work.

Obs. I am indebted for my only Chester County specimen of this, to Mr. Jcsiiua 

 Hoopks,— who collected it near Downingtown, In 18*28. 1 have not yet met with 

 it, either in flower or in fruit,— nor have 1 seen any specimen with the leaves si 

 large as that figured in Mivhaux's Sylra. It has some resemblance, as Pureh 

 remarks, to the S. amygdalina, of Europe,-! ut is still more nearly allied to 8/ 

 pentandra:— indeed, Mr. Borrer {fide Hook.) doubts if our S. lurida be distinct 

 from the European S. pentamlra.
