G. 187. ' Maori King ' X E. 233 ( = ' Mme. Chereau ' X ' Mrs. H. 

 Darwin'), 66 seeds germinated, 58 flowered, 8 died unflowered. 



The tipping of the beard in Plicatas has always seemed to me to 

 be different from the tipping in Amcenas and Variegatas (and is 

 perhaps derived from some other source), and the introduction of 

 Plicata into the cross G. 187 might have been expected to give 

 distinct results. For even though in the seedling used (E. 233) the 

 beard was not tipped, this character was probably contained latent 

 or recessive. The results are, however, comparable with those of 

 G. 190, where the tipping character (from ' Cordelia') is also introduced 

 as a recessive in the seedling C. 8. a., and these two crosses have 

 different results for this character, both from G. 189 — where there 

 is presumably less of this character (if due to cumulative factors) in 

 the parentage — and from G. 188, where there is more. These considera- 

 tions seem to point, as I have suggested, to cumulative factors.

 a-dozen hairs tipped and only to be detected with a lens.
