 Carinthia and Siberia. {Dec.

 1790, and producing its white 

 flowers in June and July. Height 

 from 3 ft. to 5 ft. It is one of 

 the handsomest species of this

 a variety of S. chaniaedrifolia L. ;

StS. (c.) u. i phylldntha Ser.— In this variety a wliorl of distinct leaves, that are petioled, lan- 

 ceolate, and sharply serrated, occupies the place of the sepals, and is described as being 

 these transformed. Petals and stamens are either not present, or deformed. Seringe 

 appears to think the S. folibsa Poir. Diet., 1. p. 353., is identical with this. l^Dec. Prod.,
