THE SHRINKING AND SWELLING SEED 191 



Table showing the Relative Weights, etc. — continued. 



If, then, we group together the results for all these seeds 

 of 82 species, we get the following arrangement : — 



Grouping of the Seed-coat Ratios for the Resting Seeds of 82 

 Species of Plants, the Weight of the Entire Seed being 



TAKEN AS 100. 



Note. — The total here is not 82 but 83, as Entada poly stocky a with its two types of 

 seeds has been entered twice. 



Since just half of the species possess seed-coat ratios The general 

 between 20 and 40 per cent, (both inclusive), it is probable that supplied by 

 the average weight of the seed-coats would be about 30 per oaj^™"!'^"^ 

 cent., rather below for leguminous seeds and rather above for coat ratios.
