Author states that, in addition to its protective func- 

 tion against too intense light and heat, the main function 

 of anthocyanin is to protect the assimilating cells against 

 those rays of light which tend to induce in the protoplasm, 

 more especially in the chlorophyll grain, a condition of 

 light rigor, and thereby to diminish or inhibit their power 

 of assimilation. See text. p. 131

A suggestion is made that, in addition to its value as a 

 screen, anthocyanin in young leaves in the tropics protects 

 the leaf against the too great heating effects of the sun's 

 rays. Experimental evidence is given in favour of this 

 view. See text. pp. 21, 22, 130, 136

Important paper on the physiological significance of 

 anthocyanin. The author favours the view that the 

 chief function of the pigment is to convert light rays 

 into heat. By virtue of this property, it has the power of 

 accelerating transpiration xmder difficult circumstances, 

 and hence its distribution in many shade-loving plants 

 in damp tropical regions. See text.

406. 1897. Ewart, A. J., 'The Effects of Tropical Insolation,' Ann. 



Bot., Oxford, 1897, xi, pp. 439-480. 



The author maintains that anthocyanin is highly 

 important in its protective action against rigor pro- 

 duced in the assimilating cell by too strong insolation. 

 Stahl's views are adversely criticised. See text.
