Hooker records S, saxatile. It is probably a synonjm of S. 

 annuum in this case, as in mauj others : or can it have been the 

 true plant, the S. (Ederi (Eetz.) ? for Hooker gives S. annuum in 

 addition, and marks the S. saxatile as added to the flora by him ; 

 also most of the lists include S, rupestre, meaning probably the 

 plant of the ' Fl. Danica,' which is apparently the same as S, an- 

 nuum ; but Hjaltalin places them as 8. annuum s. anglicum^ and 

 S, saxatile s. rupestre. It appears therefore that he thought 

 that there are two species, but was doubtful concerning their 

 names.

• Hooker does not separate this from S, Cotyledon, and did not 

 know it as Icelandic. Vahl marks it, as well as S. Cotyledon 

 as certainly a native. I am informed by Lange that nothing is 

 known at Copenhagen of S. Cotyledon (which rests mainly on the 

 authority of Zoega) or S. cuneifolia as natives of Iceland.

This is almost certainly a mistake. It is difficult to tell what 

 the S. punctata of K., Z., S., and H, may have been. It can scarcely 

 be the S. cuneifolia^ to which Hj., G., and P. & Z. apparently refer 

 it, and is hardly likely to be the r^dX S . punctata (Linn.), although 

 that plant is a native of Siberia and North-west America.]
