I. H. Barkill — Flower of Ranunculus arvensis. [No. 2 



number of its sepals, petals, stamens and carpels, and noting any obvi- 

 ous abnormalities in it. For the purpose the flowers were picked 

 when just open, and this picking, done daily, caused the plants to 

 continue long in blossom. 



In this way I examined in 1895, 1,383 flowers from Heidelberg 

 seed and 1,203 from Bonn seed ; in 1898, 2,298 from Kew 1896 seed 

 (167 plants) and 1,589 from Kew 1897 seed (73 plants) ; and also in 

 1895 lesser numbers of flowers from Paris, Stockholm, and Bordeaux 

 seed — numbers too small to be of real service. I give the results of 

 the examination of the Paris, Stockholm and Bordeaux plants here before 

 proceeding. I shall not mention them again,

As to the more profitable experiments I found the different sowings 

 to vary as follows :
