1836. S. pusilla Baumg. (Herm. Muller, ' Alpenblumen,' pp. 371-3; Schulz, 

 ' Beitrage,' II, pp. 150-1.) — Hermann Miiller says that this homogamous species 



occurs in the Alps in two 

 varieties which differ both 

 morphologically and oecolo- 

 gically. The variety pendula 

 bears bee -flowers, while in 

 the variety indinaia (Fig. 249) 

 the nectar is accessible to less 

 inielligent short-tongued in- 

 sects. In the former the bell 

 is pendulous and relatively 

 long and narrow, while in 

 the latter it is wider and 

 directed obliquely down- 

 wards. In both varieties 

 automatic self-pollination 

 by fall of pollen is 

 possible.
