with pollen from the foregoing purple variety, and these produced 11 and 22 seeds which germinated well. A large number of the stigmas on several of the other corymbs were repeatedly smeared with pollen from their own corymb; but they yielded only five very poor seeds, which were incapable of germination. Therefore the above three plants belonging to two varieties, though growing vigorously, and reciprocally fertile with pollen from one another, were utterly sterile with pollen from one another with pollen from other flowers on the same plant.)

Reseda odorata.—Having observed that certain individuals were self-sterile, I covered during the summer of 1868 seven plants under separate nets, and will call these plants A, B, C, D, E, F, G. They all appeared to be quite sterile with their own pollen, but fertile with that of any other plant.)

(Fourteen plants flowers on A were crossed with pollen from B or C, and produced 13 fine capsules. (lead on) Sixteen flowers were fertilised with pollen from other flowers on the same plant, but yielded not a one single capsule.
