PEOF. C. C. BABIKGTOy OX THE FLORA OF ICEIiAND. 295 



There are two forms of this plant in Iceland, (1) D. contorta 

 (Ehrh.), and (2) D, confusa (Ehrh.). They seem to form one 

 species, although several distinguished botanists have separated 

 them. The latter, now considered the type of the Linnaean spe- 

 cies, is, I presume, the var. stricta of Lindsay's * Flora.'

This is certainly the D. rupestris of Pries, and apparently that 

 of E. Brown. It is the D. Jdrta and oblongata of Vahl, and D. 

 hirta /3. alpicola of Wahlenberg. Tlie D, hirta of the Arctic flora 

 seems to be quite distinct from it.

Common, according to Morck. Reykjavik, Alafsdal, &c., St. 

 It is not included in many of the lists ; for Mohr, Gliemann, 

 Hjaltalin, and the manuscript lists of Morck and Steenstrup alone 

 contain it.

G-liemann, Preyer and Zirkel, and Lindsay record it, but give 

 no localities. 



-D. mitricella (Wahl.) is the same plant. 



Gliemann has D, alpina also; and it is included in Hon:ie- 

 mann's manuscripts, as I learn from Prof. Lange.

32. Teesdalia nudicaulis, R. Br, — S. 



There is a specimen of this plant, without any locality, amongst 

 Solander's Icelandic plants preserved in the British Museum. He 

 called it Iheris nudicaulis. He saw it in Paulsen's herbarium, and 

 very probably obtained the specimen from that botanist. 



33. Lepidium campestre. It. Br. — K. 



This is found in Konig's and all the succeeding lists ; but no 

 localities are recorded.
