other huge citrus also may have originated in this way 

 (vide pi. 83). If the fruit resulting from such fusions bore 

 seed, it is probable that this double character of fruit might 

 be perpetuated, and become fixed. Not improbably also 

 additional carpels might occur, by a sort of proliferation.

 tration may be cited in the fact that it has also been found 

 possible to graft a scion on the leaf in the orange." 



(//.) p. 74. Pig. 32 gives a drawing of an " anomalous 

 form of orange." 



(NOTE. I have hazarded an explanation of this anomaly 

 on pi. 241, fig. d. E. B.) 



(*') P- 75- "Disjunction is not rare in oranges. Some- 

 times this takes place regularly, at other times irregularly ; 

 occasionally in such a manner as to give the appearance of a 

 hand and fingers to the fruit." 



"M. Duchartre mentions a semi-double flower of orange 

 with eight to ten distinct carpels in a whorl, and occasionally 

 several whorls, one above another. De Candolle considers 

 the rind of the orange as a production from the receptacle, 

 and this view is confirmed by the specimens of Duchartre, 

 in which the carpels were quite naked, or had a common 

 envelope truncated, and open above to allow of the passage 

 of the styles and stigmas." 



(NOTE. I should say that not only the rind but all parts 

 of the fruit are productions from the receptacle. The fact 

 of Duchartre having found the pulp carpels quite naked or 

 rindless admits, as I have shown, of a different interpreta- 

 tion, and may only prove that the pulp carpels are quite 

 distinct from the rind carpels. E. B.) 



(/.) p. 134. Prolification of the fruit. " In many instances, 

 not only the fruit is repeated, but also the outer portions of the 

 flower, which wither and fall away, as the adventitious fruit 

 ripens ; so that, at length the phenomenon of one fruit pro- 

 jecting from another is produced. It is obvious that this 

 form of prolification in no wise differs from ordinary central 

 prolification. Sometimes some of the whorls of the adven- 

 titious flower are suppressed ; thus M. Duchartre describes 

 some orange-blossoms as representing alternating series of
