Among the finer Double-flowered Clematis, which are now becoming rather numerous, we have had an opportunity of seeing one called Duke of Connaught, a seedling from lanuginosa, having the same broad foliage, but with compact semi-double flowers of a delicate mauve colour, which on the starved seedling plant measured about 5 inches across.  The structure of the flowers in this variety is somewhat novel.  There is first the outer whorl of six ovate sepals, and then within this, diminishing in size inwards so as to form a flattish bloom, are four or five other whorls of sepals of the same colour, the centre being occupied by a tuft of whity-brown stamens on white filaments.  If constant to this form, and there is no reason to doubt it, since several flowers have been produced this season, we have here a new type, of distinct character, and of great beauty, the flowers being spread out as in the single form, yet compactly filled with petaloid sepals in the centre, so as to form a stiff, firm. solid-looking flower.  It bloomed last June with Mr. G. Jackmanm of Woking.  There is a manifest improvement in the new double forms of Clematis, the stalked, sepaled sorts, which produce loose, open flowers such as can be seen through near the centre, being replaced by others in which the centre is filled up compactly in consequence of the sepals being stalkless.  This character is well shown in Duchess of Edinburgh, the best of the whites; in Countess of Lovelace, which has been shown exceedingly fine this season; and in the Duke of Connaught above cited.
