floriferous ones erect ; leaves terete-subulate, those of the sterile 
branches spreading and glaucescent; flowering stems spreading, 
compressed; branches of cyme crowded, erect. %. H. Native 
of Siberia. The leaves, according to Haw. in rev. p. 29. are green, 
and the flowers nearly white; but according to Willd. 1. c. the 
leaves are glaucescent, and the flowers greenish-yellow, there- 
fore two species are probably confounded under this name, and 
perhaps both are only varieties of S. refléxum.
