OXALIS VALDIVIANA.

Therefore the extreme difference in diameter is as 8 5 

 to 6, or as 100 to 71. The results of Hildebrand's ex- 

 periments are given in the following table, drawn up 

 in accordance with my usual plan. He fertilised each 

 form with pollen from the two sets of anthers of the 

 same flower, and likewise from flowers on distinct 

 plants belonging to the same form ; but the effects 

 of these two closely allied kinds of fertilisation differ 

 so little that I have not kept them distinct.
