PROF. C. C. BABINGTON OK THE FLOHA OF ICELAND. 293 



This is apparently a common plant in Iceland, but has not 

 been found in Greenland or Spitzbergen, 



[Berberis vulgaris, Linn., is recorded by G-., but is not likely 

 to be a native-] 



14. Papaver alpinum, Linn, — K. 



Jokaldalr near Stafafell, and near Leera by BorgarQord, Hd. ! Ak- 

 reyri, C. ! Garpsdal, Thorisengismule, and Breidabolstad, -S'^ Stranda 

 Syssel, G, KoUaQord, M. HrutaQord, B. G. Near Holmar on 

 Reydarfjord, T, ^ G. 



Preyer and Zirkel also record P. alpinum (Linn.), which is 

 probably not distinct from P. nudicaule. Mohr and also Glie- 

 niann give P. radiatum, which is another synonym of P. nudi- 

 caule. Solander mentions doubtfully P. duhiuon on the autho- 

 rity of Paulsen's Herbarium. 



[i^asturtiiim officinale (E. Br.) is in Lindsay's ' Flora/ but in 

 no other list. I much doubt its correctness.] 



15. Nasturtium palustke, DC, — K. 



Sisymbrium islandicum, FL Dan. 409. 



S. terrestre. Hooker. 



S. palustre, var. islandicum, Hj. 



S. sylvestre, Mohr, 



By hot springs and in wet places about Krafle and Myvatn, Z. and 

 also G. . 



Dr. Lindsay places the N. ampTiilium (E. Br.) as a synonym 

 of tliis species, and P. &Z. follow him. There must be some 

 mistake or misprint. Hjaltalin has N. amphihinm, var. terrestre, 

 which may be the iV. am^hibium, but is more probably the pre- 

 sent plant. 



16. Arabis alpina, Linn. — K".

 fjord, T. 4- G. Thingvellir and Esia, St. Oxnedalrheidi, Kr. Ska-

Brassica alpina, which is not different from this plant, is also 

 recorded by Gliemann. 



\8inapis arvensis is considered a native by Gliemann.] • 



17. A. PETR^A, Linn.—K. 

 Cardamine faeroensis (G.). 

 C. petraea (G.).
