Spec. Char., Sfc. Stem shrubby, branched. Branches erect, terete, iioarv, to- 

 mentose. Leaves on short footstalks, narrow-linear, or linear-lanceolate, 

 with revolute margins; luulcr surface hoary, upper surface greenisli, shining. 

 Stipules awl-shapeti, longer than the footstalks of the leaves. Pciiicels 

 hoarj-. Calyxes nervously furrowed, brownish violet. (Uons Alill., i. p. 

 .'312.) A native of Spain, Barhary, and Tcneriffe, and in cultivation in the 

 Bristol Nursery in 1828. It is a very beautiful species, with large white 

 Howers, having imbricate crenulate petals, and tiie sepals mai'ked with red 

 or violet. It is readily distinguishcii, Sweet observes, from all the others 

 of its section, by its upright growth, glossy leaves, and the red veins of its 

 sepals. Its flowers are produced nearly the whole sunnner, and it re- 

 quires very little protection during the winter.
