On the Production of Hybrid Vegetables. 



POSTSCRIPT. 



I have omitted to state the few observations I had made 

 respecting the prevalence of the male or female type in hybrid 

 vegetables. It appears that where there is a difference be- 

 tween the anthers and filaments of the parents, the mule may 

 be expected to follow the male in that respect ; and on the 

 other hand, where the distinction lies in the style or stigma, 

 I believe that that part of the mule will be found conformable 

 to the female parent. Amaryllis Reginse has the stigma less 

 divided and more clavate than any other known Amaryllis ; 

 the mule Amaryllis Reginae-vittata has the more trifid stigma 

 of A. vittata, the female. I have seen no other mules from 

 plants which differed in the form of the stigma or style. 

 The mules raised from Azalea, impregnated by Rhododen- 

 dron, have the ten anthers of Rhododendron, the male, or 

 nearly that number. The hybrid Crinum Govenium has the 

 filaments curved, like those of C. Zeylanicum, the male, 

 which are much more bent than those of C. Capense, the 

 female, parent. The filaments of A. fulgida are in pairs of 

 three lengths ; those of A. rutila, a species closely allied to 

 it, are, like those of A. Reginae, more irregular, sometimes of 

 four different lengths, and sometimes of only two alternately. 

 The mules from A. rutila impregnated by A. fulgida, have 

 the filaments in three pairs, like their male parent. The form 

 and colour of the leaves and corolla in mules, appear to be 

 generally intermediate, partaking of the habits of both pa- 

 rents, and probably uniform or variable, according as they 

 are more or less apt to produce seminal varieties. In the
