(4) In addition to the above several other crosses were made but an 

 insufficient number of seedlings had been obtained to make them worth 

 while describing at any length. 



(a) Crosses were made between a single form with njsy-pink petals 

 and the double Howered "Ballet Girl" with white petals. Offspring pro- 

 duced flowers which had rosy-pink petals and there were numerous 

 grades among them between completely single flowers and completely 

 double ones. 



(6) Fuchsia procumbens (^)x F. refiexa ((/ ). Only a single seedling 

 was produced from this cross. The upper branches of the plant were 

 erect like those of F. refiexa whilst the lower ones were trailing like 

 those of the female parent. The flowers were small, with pale pink 

 sepals and a corolla reduced to a small deep pink scale. The stamens 

 were very rudimentary and completely sterile. The pistil possessed a 

 four-lobed stigma ; the style being pink and the stigma a lighter shade 

 of the same colour. 



(c) A number of crosses were made between F. Gottinghami ( $ ) and 

 F. refiexa {(^); and between F. parvifiora(^ ) and F. refiexa {^). In 

 both cases the female parent possessed completely sterile anthers whilst 

 the male parent {F. refiexa) produced good, fertile pollen. The object of 

 the cross was to test the inheritance of the fertile and sterile character 

 of the pollen in the two parents. 



Results were not carried far enough to deal with the point efficiently 

 but one seedling was obtained from crossing F. Cottinghami with F. refiexa 

 in which the pollen was perfectly fertile and resembled that of F. refiexa 

 in possessing two interstitial bodies. 



Further crosses were made between this seedling (No. 7)((/) and 

 F. Cottinghami { $ ). In the offspring of this cross either all the stamens 

 were sterile or in some cases (e.g. No. f^) a certain amount of fertile 

 pollen with two interstitial bodies was produced amongst a quantity of 

 grains which were empty and bad. 



The work for this paper was carried out at the John Innes Horti- 

 cultural Institution and I wish to express here my most sincere thanks 

 to Mr Bateson for the facilities which were attorded me aiid for the 

 interest he has taken in the work.
