and was rather more fertile than the last, yet many of the anthers 

 were eontabescent. 



Exp. XVI. This short-styled plant, treated like the two last, 

 yielded from ten capsules an average of 77'8 seeds, with a maximum 

 of 97 and a minimum of 60 ; so that this plant produced 94 per 

 cent, of the full number of seeds, 



Exp. XVII. This, the one long-styled plant of the same parentage 

 as the last three plants, when freely and legitimately fertilized in 

 the same manner as the last, yielded an average from ten capsules 

 of 76*3 rather poor seeds, with a maximum of 88 and a minimum 

 of 57. Hence this plant produced 82 per cent, of the proper 

 number of seeds. Twelve flowers under a net were artificially 

 and legitimately fertilized by pollen from a legitimate short- 

 styled plant ; and nine capsules yielded an average of 82*5 seeds, 

 with a maximum of 98 seeds and a minimum of 51 ; so that its 

 fertility was increased by the action of pollen from a legitimate 

 plant, but still did not reach the normal standard. 



Class III. Illegitimate plants from the mid-styled form fer- 

 tilized hy pollen from tlie longer stamens of the same form. 



After two trials, I succeeded in raising only four plants from 

 this illegitimate union. These proved to be three mid-styled and 

 one long-styled ; but from so small a number we can hardly 

 judge of the tendency in mid-styled plants when self-fertilized 

 to reproduce the same form. These four plants never attained 

 their full and normal height \ the long-styled plant bad several of 

 its anthers eontabescent. 



Exp. XVIII. This mid-styled plant, when freely and legiti- 

 mately fertilized during 1865 by illegitimate plants descended 

 from self- fertilized 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 number of seeds. Twelve flowers were 

 artificially and legitimately fertilized by 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 

 maxhiium of 135 and a minimum of 75 ; so that, as in Exp. Xl II., 

 pollen from a legitimate plant increased the fertility, but did not 

 bring it up to the full standard. 



Exp. XIX. This mid-styled plant, fertilized in the same manner 

 and at the same period with the last, yielded an average from ten 

 capsules of 731 seeds, with a maximum of 87 and a minimum ot 

 64 ; hence this plant produced only 56 per cent, of the full number
