 cent; sterile stems somewhat reflexed. S. recurvatum, Willd. 

 enum. suppl. 23. Perhaps a variety of S. albescens, according 

 to Haw.

79 S. VI'RENS (Ait. hort. kew. 2. p. 110.) leaves scattered, 

 subulate, green, loosened at the base ; flowers cymose ; petals 

 lanceolate, much longer than the sepals. "!. H. Native of 

 Portugal. S. reflexum, Willd. enum. suppl. p. 25. S. crassi-

80 S. VIRE'SCENS (Willd. enum. suppl. p. 25.) stems branched: 

 floriferous ones erect ; leaves terete-subulate, those of the sterile 

 branches spreading and glaucescent ; flowering stems spreading, 

 compressed; branches of cyme crowded, erect. 1. 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. reflexum.
