The Complete Work of Charles Darwin Online (82 Papaver vagum (1867) from Dr E. Bornet of Antibes. 10 flowers crossed with pollen from distinct plant produced 7 fine capsules, all containing hundreds of seeds. 15 fl. fert. with own pollen, produced 10 capsules, but 5 of these may be almost rejected, for they contained only from 1 to 7 good seeds— of the 5 moderately good capsules, 4 contain 1 alone equalled one of the better but not best capsules of crossed plants, the 4 others containing only

oftener imperfect than is generally supposed. Dr. E. Bornet, of Antibes, informs me (through Mr. J. Traherne Moggridge) that with hybrid Cisti the ovarium is frequently deformed, the ovules being in some cases quite absent, and in other cases incapable of fertilisation. Several theories have been propounded to account for the origin of C. adami, and for the transformations which it undergoes. These transformations have been attributed by some authors to simple bud-variation; but considering the wide

and in other cases all those down one side of the spike, with pollen of other varieties, and the remaining flowers with their own pollen. I saw these plants when the capsules were nearly mature, and their curious arrangement at once brought full conviction to the mind that an immense advantage had been derived from crossing these hybrids. Lastly, I have heard from Dr. E. Bornet, of Antibes, who has made numerous experiments in crossing the species of Cistus, but has not yet published the

when growing in the same garden, as I have known to be the case with P. bracteatum and orientale. Plants of Papaver vagum were raised from seeds sent me from Antibes through the kindness of Dr. Bornet. Some little time after the flowers had expanded, several were fertilised with their own pollen, and others (not castrated) with pollen from a distinct individual; but I have reason to believe, from observations subsequently made, that these flowers had been already fertilised by their own pollen, as
