glabrous. Calyx glabrous, erect, of four oblong leaflets, 
tinged with purple, two opposite ones saccate at the base. 
Petals obovato-cuneate, retuse, clawed at the base, of a 
delicate, purplish, rose-colour, twice as long as the calyx. 
Stamens shorter than the petals. Anthers oblong, yellow. 
Pistil, linear, filiform, erect. Stigma scarcely dilated, 
notched. 
This very pretty species of Rock-Cress will in all proba- 
bility prove hardy, and amply deserving of cultivation on 
account of its graceful and drooping raceme of pale purple 
flowers. Seeds of it were sent to our Botanic Garden, by 
Dr. Fiscuer of St. Petersburgh, and the plant has been 
hitherto with us confined to the frame. It is a native of 
hills in the environs of Naples ; but I am not aware that it 
has any where been figured.
