Chap. SI. SEGREGATION OF CHARACTERS. 425 



On the segregation of the parental characters in seminal hybrids 

 by bud-variation. — I will now give a sufficient number of 

 cases to show that segregation of this kind, namely, by buds, 

 may occur in ordinary hybrids raised from seed. 



Hybrids were raised by Gartner between Tropceolum minus and 

 majus 116 which at first produced flowers intermediate in size, colour, 

 and structure between their two parents ; but later in the season 

 some of these plants produced flowers in all respects like those of 

 the mother-form, mingled with flowers still retaining the usual 

 intermediate condition. A hybrid Cereus between C. speciosissimus 

 and phyllanthus, 117 plants which are widely different in appearance, 

 produced for the first three years angular, five-sided stems, and 

 then some flat stems like those of C. }>hyllanthus. Kolreuter also 

 gives cases of hybrid Lobelias and Verbascums, which at first 

 produced flowers of one colour, and later in the season, flowers of a 

 different colour. 118 Naudin 119 raised forty hybrids from Datura 

 kevis fertilised by I), stramonium ; and three of these hybrids 

 produced many capsules, of which a half, or quarter, or lesser 

 segment was smooth and of small size, like the capsule of the pure 

 D. lodvis, the remaining part being spinose and of larger size, like 

 the capsule of the pure D. stramonium : from one of these com- 

 posite capsules, plants perfectly resembling both parent-forms were 

 raised. 



Turning now to varieties. A seedling apple, conjectured to be of 

 crossed parentage, has been described in France, 1 - which bears 

 fruit with one half larger than the other, of a red colour, acid taste, 

 and peculiar odour ; the other side being greenish-yellow and very 

 sweet : it is said scarcely ever to include perfectly developed seed. 

 I suppose that this is not the same tree as that which Gaudichaud 121 

 exhibited before the French institute, bearing on the same branch 

 two distinct kinds of apples, one a reinette rouge, and the other like a 

 reinette Canada jaundtre : this double-bearing variety can be propa- 

 gated by grafts, and continues to produce both kinds ; its origin is 

 unknown. The Eev. J. D. La Touche sent me a coloured drawing 

 of an apple which he brought from Canada, of which half, surround- 

 ing and including the whole of the calyx and the insertion of the 

 foot-stalk, is green, the other half being brown and of the nature 

 of the pomme gris apple, with the line of separation between the two
