A FURTHEK NOTE UN THE GENETICS 

 OF FRAG ARIA. 



By C. W. RICHARDSON. 



My work on Fruguria has been somewhat intermittent in character 

 for the last three years owing to other calls on my time, accordingly 

 many experiments I hoped to continue, when I wrote my first " note " 

 to this Journal (Vol. in. No. 3, Feb. 1914), I have been obliged to leave 

 on one side for a future date ; also a considerable amount of seed gathered 

 from plants in 1914 has either failed to germinate or germinated badly. 

 But there is an ever growing bundle of facts which time might tend to 

 render stale or to submerge under fresh detail, and it is this accumu- 

 lation I would add to the record. 



Once again I express my gratitude to the John Innes Horticultural 

 Institution for the facilities they have afforded me in carrying on my 

 work, at a time when labour is very short and there are few to answer 

 the numerous calls of a garden " in being." 



Flower Colour. It is difficult to distinguish between very light 

 pinks and pure whites, so much so that I have found it impossible to 

 draw a clear line between them after 5 p.m. in June, when, as a rule, in 

 England the light tends to become red. 



As stated, in my previous paper, the ci-oss pink flowering resca x white 

 flowering vesca produced pink flowering F^'s. These selfed produced 

 20 Pink, 57 Pale jjink, 10 White or very nearly white (of the latter at 

 least 3 were absolutely white). 



Expectation 1 to 1.5 — 81 -57 Pink to 5-43 White. 



Double flowering. My original double nesca parents were hardly so 

 consistent in their double quality as one might desire, but they were 

 (|uite as double as any I have seen elsewhere or obtained in my F.. 

 generations, the leading flowers in a truss are generally the most double 

 and are frequently perfect.
