Chap. XL FLOWERS. 401 



one berry half red and half white. 12 Alexander Braun 13 .also has 

 often seen branches on white currant-trees bearing red berries. 



Pear (Pyms communis). — Dureau de la Malle states that the 

 flowers on some trees of an ancient variety, the doyenne galeux, were 

 destroyed by frost : other flowers appeared in July, which produced 

 six pears; these exactly resembled in their skin and taste the 

 fruit of a distinct variety, the gros doyenne blanc, but in shape 

 were like the lon-chretien : it was not ascertained whether this 

 new variety could be propagated by budding or grafting. The 

 same author grafted a bon-chretien on a quince, and it produced, 

 besides its proper fruit, an apparently new variety, of a peculiar 

 form with thick and rough skin. 14 



Apple (Pyrus mahis). — In Canada, a tree of the variety called 

 Pound Sweet, produced, 15 between two of its proper fruit, an apple 

 which was well rnsseted, small in size, different in shape, and 

 with a short peduncle. As no russet apple grew anywhere near, 

 this case apparently cannot be accounted for by the direct action 

 of foreign pollen. M. Carriere (p. 38) mentions an analogous 

 instance. I shall hereafter give cases of apple-trees which regu- 

 larly produce fruit of two kinds, or half-and-half fruit ; these trees 

 are generally supposed, and probably with truth, to be of crossed 

 parentage, and that the fruit reverts to both parent-forms. 



Banana (Musa sapientiurn). — Sir E. Schomburgk states that he 

 saw in St. Domingo a raceme on the Fig Banana which bore 

 towards the base 125 fruits of the proper kind; and these were 

 succeeded, as is usual, higher up the raceme, by barren flowers, 

 and these by 420 fruits, having a widely different appearance, and 

 ripening earlier than the proper fruit. The abnormal fruit closely 

 resembled, except in being smaller, that of the Musa chivensis or 

 cavendishii, which has generally been ranked as a distinct species. 16 



Flo wees.— Many cases have been recorded of a whole plant, or 

 single branch, or bud, suddenly producing flowers different from 

 the proper type in colour, form, size, doubleness, or other character. 

 Half the flower, or a smaller segment, sometimes changes colour. 



Camellia. — The myrtle-leaved species (C. myrtifolia), and two or 

 three varieties of the common species, have been known to produce 

 hexagonal and imperfectly quadrangular flowers ; and the branches 

 producing such flowers have been propagated by grafting. 17 The 

 Pompon variety often bears " four distinguishable kinds of flowers, 

 '* — the pure white and the red-eyed, which appear promiscuously ; 

 ■'* the brindled pink and the rose-coloured, which may be kept
