STUDIES IN SEEDS AND FRUITS 



TABLE ILLUSTRATING THE EFFECT OF HAIRS ON THE PROPORTIONAL 

 WEIGHT OF THE SEED-COATS IN RESTING SEEDS. 



* The proportional weight of the hairs was alone ascertained. 



t In Gossypium (hirsutum ?) the cotton adheres firmly to the black seed, becoming 

 dirty grey and matted next to the seed. Of the relative weight of the hairy covering 

 (43'5 P er cent -)> white cotton forms 37*1 and the grey matted portion 6*4. 



In G. barbadense the cotton easily separates from the black seed, there being no 

 adherent covering of matted hairs.
