Hybrid Clematis.

A paper was received from M. Morel on "Hybrids and Mongrels of Clematis," and these may be considered under his various sub-headings.

Clematis coccineo-Pitcheri.—The first experiment in crossing Clematis coccinea♂ and C. Pitcheri♀, which belong to the same group, produced a large number of fertile seeds. The seedlings obtained were chiefly interesting from their resemblance inter se, and constituted a form intermediate between the species they were derived from (see E. André, Revue Horticole, August, 1893, for a detailed description of the hybrid, as well as for figures of itself and its parents). From C. coccinea it gets its habit of early flowering and its colour, while from C. Pitcheri its vigour, its sepals reflected at their extremities, and its sweet vanilla-like scent. This hybrid seeds copiously and reproduces itself almost exactly, but if pollen from one of the parent species is used, a large number of forms is obtained, that more nearly resemble the pollen parent. Its fertility is adduced as evidence of the near relationship of C. coccinea and C. Pitcheri.

Hybrid No. 378.—This is between C. coccinea ♂ and a large-flowered Clematis as yet unnamed (No. 140)♀, two species which belong to very different groups. The pollen parent contributes the consistence and a number of sepals. The flower is intermediate in form between the urceolate blossoms of C. coccinea and the spreading ones of No. 140, which latter gives the colour. The leaves are more like that of the former species, and the hybrid has proved sterile up to the present.

Hybrid No. 401.—This hybrid, though having the same pollen parent as the last, and produced also from the seeds of a large-flowered Clematis (Oriflamme), almost completely retains the characters and habits of C. coccinea. The number of its sepals is variable, being sometimes four as in the latter species, sometimes five or six as on the other parent. No. 401 has always proved sterile.

Clematis à Ville de Lyon. — This, which M. Morel considers the most beautiful form of the genus yet obtained, was described and figured in the Revue Horticole of April 16, 1899. The parents are C. coccinea ♂, and a large flowered form called Viviand Morel, and the appearance of the progeny at first sight seems to belie its origin. The foliage of the hybrid is altogether that of a large-flowered form; the enlarged open flowers in no way recall the sepals of C. coccinea, to which its other hybrids retained some resemblance. The colour of the blossoms, as well as the number, dimensions, and arrangement of the stamens, agree with the pollen-parent, which it also resembles in its constitution, being immune against the attacks of the terrible disease that attacks the large-flowered species of Clematis. M. Morel quoted a parallel case of the hybrid Paeonies between Paeonia officinalis♀, and P. Rossii♂, which altogether resemble the seed-parent.
