196 ILLEGITIMATE OFFSPEING OF Chap. V. 



capsules was only 35-9 seeds, with a maximum of 60 and 

 a minimum of 8. 



Plant 12. This long-styled plant produced very few capsules, 

 and ten yielded an average of only 15 • 4 seeds, with a maximum 

 of 30 and a minimum of 4. 



Plant 13. This plant offers an anomalous case ; it flowered 

 profusely, yet produced very few capsules; but these con- 

 tained numerous seeds. Ten capsules yielded an average of 

 71 "9 seeds, with a maximum of 95 and a minimum of 29. Con- 

 sidering that this plant was illegitimate and illegitimately fer- 

 tilised by its brother long-styled seedlings, the average and the 

 maximum are so remarkably high that I cannot at all under- 

 stand the case. We should remember that the average for a 

 legitimate plant legitimately fertilised is 93 seeds. 



Class III. Illegitimate Plants raised from a Short- 

 styled Parent fertilised with pollen from own-form 

 m/id-length stamens. 



I raised from this union nine plants, of which eight 

 were short-styled and one long-styled ; so that there 

 seems to be a strong tendency in this form to repro- 

 duce, when self-fertilised, the parent-form; but the 

 tendency is not so strong as with the long-styled. 

 These nine plants never attained the full height of 

 legitimate plants growing close to them. The anthers 

 were contabescent in many of the flowers on several 

 plants. 



Plant 14. This short-styled plant was allowed during 1865 to 

 be freely and legitimately fertilised by illegitimate plants de- 

 scended from self-fertilised mid-, long-, and short-styled plants. 

 Fifteen capsules yielded an average of 28 '3 seeds, with a 

 maximum of 61 and a minimum of 11 ; hence this plant 

 produced only i]3 per cent, of the proper number of seeds. The 

 seeds themselves were small and irregular in shape. Although 

 so sterile on the female side, none of the anthers were conta- 

 bescent. 



Plant 15. This short-styled plant, treated like the last during
