NOTES ON SOME HYBRID TUBEROUS SOLANUMS.

improved " etuberosum " ; second largest tuber diseased, several pushing 

 November 24. (Too long in ground.) 



11. Not noted, September 14 : Eighteen tubers, white, round, early, no 

 disease ; yellow flesh, very fine ; two pushing November 24. 



12. Not noted, September 15: Poor plant ; roots all gone ; five 

 tubers. 



13. Not noted, September 23 : Eight tubers, white with violet tint ; 

 good. 



14. No note made. 



Another cross of S. " etuberosum " x Chilian variety gave twenty- 

 two seedlings, some noteworthy. 



I may mention the remarkable fact that a seedling plant of S. 

 "etuberosum" "selfed" produced 481 tubers (probably 500, as some 

 were lost), weighing over 3 lb., white, with no trace of disease. The 

 flower of this plant is white tinged with violet, the back of the petals being 

 pale violet with white edges ; the plant very strong, foliage also showing 

 no disease. [A cross of this with [a] has given two good berries.] These 

 selfed seedlings were planted out too late for the tubers to attain their 

 proper size, but I have never known a cultivated seedling to produce so 

 many tubers, although I have raised upwards of 13,000.
