generation . . . tbe coloured portions begin to predominate. 

 ... I have never been able to ob.serve a single instance of 

 variegation coming directly from the coloured original. The 

 contrary, however, takes place with regard to the dottings; 

 these come directly from the coloured type." The variegated 

 varieties the author had succeeded in fixing were Goinphrena 

 globosa ; Antirrhinun majus. Convolvulus tricolor, Nemophila 

 indgnis, Portulaca grandiflora and Delphinium Ajacis. 



Other florists have found that by crossing whole-coloured 

 flowers pure white seedlings may result. 



Abu(ilons have an instructive and, in part, a somewhat 

 similar history. No hybrids were raised from the old bronze- 

 red and striped form, which was usually barren, until the 

 white " Boule de Neige " was introduced. Mr. George 

 crossed this with " Duke of Malakoff." The white one had 

 itself previously thrown up every shade of dingy white ; but 

 whether by being spontaneously crossed or not, does not 

 appear to be known. Some of tlje colours of the seedlings 

 of this cross were pale and dark pink, pale orange, bright 

 carmine, salmon, orange-red, etc.* 



Somewhat analogous results were obtained by Mr. Veitch 

 with Bihododendrons imported from Borneo. Thus a cross 

 between the larger-flowered B. Javanicum, which is orange- 

 coloured, with the smaller white narrow-lobed B. Jasmini- 

 florum, gave rise to the ro.se-coloured " Princess Royal." A 

 further cross of the last with the parent B. Jasminiflorum 

 eliminated the red colour ; the offspring, however, retained 

 the form and size of the corolla of the " Princess Eoyal." 

 It is called " Princess Alexandra." 



In the above-mentioned the effect of the white has been 

 to separate the tints ; so that from the old Bronze-red 

 Abutilon Danoinii we get yellows and reds of different
