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 polystachya with its two types of 

 seeds has been entered twice. 



The general 

 indications 



Since just half of the species possess seed-coat ratios 

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

 the average weight of the seed-coats would be about 30 per oahYseed 

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