198 ILLEGITIMATE OFFSPRING OF Chap. V. 



full and noTmal height; the long-styled plant had sev- 

 eral of its anthers contabescent. 



Plant 18. This mid-styled plant, when freely and legiti- 

 mately fertilised during 1865 by illegitimate plants de- 

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

 plants, yielded an average from ten capsules of 102.6 seeds, 

 with a maximum of 131 and a minimum of 63. Hence this 

 plant did not produce quite 80 per cent, of the normal num- 

 ber of seeds. Twelve flowers were artificially and legiti- 

 mately fertilised with pollen from a legitimate long-styled 

 plant, and yielded from nine capsules an average of 116.1 

 seeds, which were finer than in the previous case, with a 

 maximum of 135 and a minimum of 75; so that, as with 

 Plant 17, pollen from a legitimate plant increased the fer- 

 tility, but did not bring it up to the full standard. 



Plant 19. This mid-styled plant, fertilised in the same 

 manner and at the same period as the last, yielded an aver- 

 age from ten capsules of 73.4 seeds, with a maximum of 

 87 and a minimum of 64. Hence this plant produced only 

 66 per cent, of the full number of seeds. Thirteen flowers 

 were artificially and legitimately fertilised with pollen 

 from a legitimate long-styled plant, and yielded ten cap- 

 sules with an average of 95.6 seeds ; so that the application 

 of pollen from a legitimate plant added, as in the two pre- 

 vious cases, to the fertility, but did not bring it up to the 

 proper standard. 



Plant SO. This long-styled plant, of the same parent- 

 age with the two last mid-styled plants, and freely fer- 

 tilised in the same manner, yielded an average from ten 

 capsules of 69.6 seeds, with a maximum of 83 and a mini- 

 mum of 52. Hence this plant produced 75 per cent, of the 

 full number of seeds. 



Class V. Illegitimate Plants raised from a Short-styled 

 Parent fertilised with pollen from the mid-length 

 stamens of the long-styled form. 



In the four previous classes, plants raised from the 

 three forms fertilised with pollen from either the longer 

 or shorter stamens of the same form, but generally not'
