This dark flowered offspring (F) remained dwarf, and 

 only produced a comparatively small number of flowers. 

 Both its stem and the ribs of its fruits developed antho- 

 cyanin. The other dwarf descendant (A) had small leaves 

 and anthocyanin developed in its stem. Its flowers were 

 red, but it ceased flowering in the first week of August, 

 and so produced very few offsprings. 



Of the tall descendants, the four which produced red 

 flowers were all very much alike (D, E, H, I). Both 

 stems and peduncles developed anthocyanin, and, though 

 not very tall plants, were distinctly not of dwarf habit, 

 and produced an elongated main stem some two feet in 

 height The flowers were bright red, very fertile, but 

 some of them stopped flowering after the second week in 

 August, when cold wet weather set in. 



The four yellow-flowered offspring (B, C, G, K) 

 agreed in their general vegetative characters, tallness and 

 absence of anthocyanin, but were of two distinct types, as 

 indicated by their flowers. Two of them (B and C) had 

 light yellow-coloured petals, with dark claret-coloured 

 honey guides, which were, however, slightly lighter in one 

 case (C) than in the other (B). They agreed also in the 

 fact that they remained practically sterile, as hardly any 

 of their stamens produced ripe pollen. 



In the two other yellow-flowered forms (G and K) the 

 honey guides were bright red, not claret-coloured, and 

 these plants were quite fertile, maturing their pollen quite 

 freely. At the end of the first week of August, which 

 was hot and sunny, one of the plants (G) produced a few 

 parti-coloured flowers, and in the second week in August 

 some completely red flowers. Even though completely 

 red, an undercurrent of yellow was sometimes visible, 

 there being often a yellow fringe at the inside of the 

 petals. As in the parental form, the red colouring always
