rigid leaves and their more glaucous colour. These leaves are scarcely 

 at all serrated and only so towards the extremity ; and the nerve, when 

 it reaches the middle, dilates and unites with the substance of the leaf, 

 which hence becomes thick and rigid, remaining nearly as straight when 

 dry as it is when moist.

Rocks, in alpine districts. Fr. June.— In this and other species of

 innovations of the stems, which are from 1—4 inches in length, erect. 

 Leaves short, patent and recurved when wet.
