267 females and 28 hermaphrodites, thus nearly 9 : 1 or 9,5 % 

 hermaphrodites, see Table 1. 



TABLE 1. 

 Polemoniiim coenileiim. 



Amongst the 18 hermaphrodites in Exp. 4b two were self-fer- 

 tilized in 1919; both gave a rather meagre and much complex 

 offspring: No. 497b gave 12 females, 5 hermaphrodites and 2 ab- 

 normal plants with no fully developed flowers, and No. 497 c 

 gave 6 females and 3 hermaphrodites, but as a few of these plants 

 were blue-flowered there are probably some experimental 

 errors and the figures are not fully reliable. 

 Also one of the 3 hermaphrodites in Exp. 4c (No. 498d) was 

 self-fertilized with result that the offspring contained 14 females 

 (2 white-flowered and 3 with bipinnate leaves) and 9 hermaphro- 

 dites (3 white-flowered).

' If we dare draw any conclusion from these very insufficient 

 dates it would be that the ratio of hermaphrodites is much 

 larger (34 % §) when we cross females with some more deve- 

 loped stamens with hermaphrodites or self-fertilize hermaphro-
