Primula sinensis, White-flowered Varieties of. By Dr. F. 



Keeble and Miss C. Pellew {Jour. Gen. i. pt. i. p. 1, Nov. 1910). — ■ 

 Two kinds of white-flowered varieties of Primula sinensis are known : 

 one has reddish stems, the other green. Breeding experiments suggest 

 that the coloured-stemmed whites carry the factors for colour but that 

 pigment formation is inhibited by the presence of a dominant white 

 factor. Similarly, the green-stemmed whites lack the dominant white 

 factor as well as one or more of the colour factors. The green-stemmed 

 white variety * Pearl ' has, however, been shown to be a dominant 

 white. The present note records some apparent exceptions to the rule 

 of dominant white among coloured-stemmed white varieties. The 

 grounds for considering the variety , ' Snow King ' a recessive white 

 with dark-red stems are set out. ' Snow King ' was also crossed with 

 * Snowdrift, ' a white-flowered variety, and twenty-four magenta- 

 flowered plants with reddish stems were produced in — F. J. C.
