 Arabis alpina L. 



Kun 6: On the hills at some 700 m. (Trevelyan). No specimens 

 are to be found in the collection of the Botanical Gardens, Copenhagen, 

 but as it can hardly be a confusion I give it on the authority of Trevelj'an. 



85. A. petraea (L.) Lam. 



Common on bare gravelly stony ground in the hills from about 

 200 m., also frequent on rock-ledges and in crevices of rocks. 



It varies considerably as regards the dentation and hairiness of 

 the leaves, the number of stem-leaves, and the size and form of the petals. 

 Fl. June — July. Fr. August. 



Older authors have given this species many names: Arabis hispida f. bastu- 

 lata Horn. is the hairy form; Cardamine faeroénsis Horn. the glabrous form 

 with deepljr pinnatifid leaves; and lastl}' Martins's Lepidium alpiniim {Hiilschinsia 

 alpina) is doubtless also identical with the latter form.
