C. PERFECTA (Simon-Louis).—This is a variety of the lanuginosa type, with simple or ternate leaves, the leaflets being cordate-ovate and acuminate. The flowers are six to eight-sepaled, of rather large size, French-white bleaching to pure white, the stamens having white filaments and pale yellowish anthers ; the sepals are broadly ovate and apiculate, forming a full and handsome flower. It bears a close resemblance to the many pale- flowered varieties of C. lanuginosa, which have orginated on the Continent.
