C. RENAULTII CŒRULEA GRANDIFLORA (Dauvesse) .- This is a very hardy and very handsome hybrid, raised by M. Dauvesse, from C. Viticella venosa, probably crossed with C. lanuginosa, and having the general habit and foliage of the Jackmanni group. The flowers are large, abundant, and successional, having well-rounded sepals of a beautiful violet-blue, with the central bar of a purplish-rose, the stamens, which are of a rosy hue, forming a conspicuous central tuft. It appears to be much esteemed in the Continental collections, and as we learn from M. Dauvesse, flowers very freely in the spring, and still more abundantly in the autumn, continuing on until arrested by frost.
