C. VIOLACEA, De Candolle. -This species, which we have not met with, is described as being allied to C. dahurica, having ternately or biternately cut leaves, with ovate segments oblique at the base ; and the flowers on trichotomous peduncles, with oblong- linear blunt sepals. Its native country is not known, but it appears to have been cultivated in the Geneva garden, since a figure of it occurs in De Candolle's Neuvième Notice sur les Plantes Rares du Jardin de Genève (t. 1) , and in the Annales de Gand (1845, t . 45) .
