 Wall-Cress. 



Class and Order. 

 Tetradynamia Siliquosa.

Specific Character and Synonym. 



Arabis caucasica; foliis spathulato-oblongis canescentibus 

 aequaliter grosse dentatis : caulinis sagittato-amplexicau- 

 libus basi integerrimis. Willd. Enum. SuppL p. 45. 



This species is very nearly related to Arabis alpina (supra 

 225), but at the same time is sufficiently distinct, being alto- 

 gether more canescent, cauline leaves sagittate at the base, and 

 having only two, or rarely three, equal, coarse teeth, on each 

 side towards the point, the rest of the leaf being quite entire. 

 It flowers very early in the spring, and continues to blossom 

 throughout the summer.
