Adonis aestivalis 1867

15 fl crossed all set, & contained average of 32.5 seed (strictly achenia, I suppose)

19 self-fert & all set, & contained average of 34.5 seed.

So self- most fertile!!!

487 crossed seed weighed 81.14 gr ∴ 655 wd. have weighed 109.1

655 self-fertilised weighed 110.31 gr. Therefore self- seed a shade heavier!!

(Pot I selfs all dead)

[Table excised] } both side flowered together

All miserable unhealthy Plants self- flowered first
