by this treatment. Of these racemes only Only three of them produced any pods, each a single one; and these three pods contained one, four, and five seeds. So that only one 2 a single pod from the se racemes included a fair complement of seeds.

Cuphea purpurea (Lythraceæ) produced no seeds, whilst other flowers on the same plant artificially fertilised under the net yielded seeds.

Vinca major (Apocynaceæ) is generally quite sterile, but sometimes sets seeds when artificially fertilised: see my notice Gard. Chronicle, 1861. p. 552.

V. rosea (dº) behaves in the same manner as the last species: Gardeners' Chronicle, 1861. p. 699, 736, 831.

Tabernæmontana echinata. (dº). quite sterile.

Petina violacæa (Solanaceæ), quite sterile, as far as I have observed.

Solanum tuberosum (dº) Tinzmann says (Gard. Chronicle, 1846 p. 183) that some vars. are quite sterile unless fertilised by pollen from another variety.
