CYCLAMEN TERSICUM. 



Chap. VI. 



was 9 "49 inches. After a considerable interval of time the 

 self-fertilised plants flowered, and several of their flower-stems 

 (but I forgot to record how many) were roughly measured, and 

 their average height was a little under 7 ' 5 inches ; so that the 

 flower-stems on the crossed plants to those on the self-fertilised 

 were at least as 100 to 79. The reason why I did not make 

 more careful measurements of the self-fertilised plants was, that 

 they looked such poor specimens that I determined to have them 

 re-potted in larger pots and in the following year to measure 

 them carefully ; but we shall see that this was partly frustrated 

 by so few flower-stems being then produced. 



These plants were left uncovered in the greenhouse ; and the 

 twelve crossed plants produced forty capsules, whilst the 

 twelve self-fertilised plants produced only five ; or as 100 to 12. 

 But this difference does not give a just idea of the relative 

 fertility of the two lots. I counted the seeds in one of the finest 

 capsules on the crossed plants, and it contained seventy-three ; 

 whilst the finest of the five capsules produced by the self- 

 fertilised plants contained only thirty-five good seeds. In the 

 other four capsules most of the seeds were barely half as large 

 as those in the crossed capsules.

Cyclamen persicum : implies that no floiuer-stem was produced.
