General account of the physiological significance of 

 anthocyanin.

Red spots on the stem are found to correspond to an 

 area of epidermal anthocyanin-containing cells round the 

 stomata. Beneath this area is assimilating tissue. The 

 suggestion is made that anthocyanin protects chlorophyll 

 from too intense light.

iiettarii estranuziali dell' Ailanthus glandulosa,' Boll. Soc. 

 boi. ital., Firenze, 1899, pp. 103-112. 



Suggestion that anthocyanin acts as a screen against 

 too bright light and excessive transpiration.

tung von Laubblattern,' Beihefl z. Bot. Centralbl., Cassel, 

 1901, x, pp. 53-89. 



Slight reference to the significance of anthocyanin as a 

 light screen.

Distribution of anthocyanin in plants growing in 

 various situations, wet and dry. shady and sunny. Short 

 discussion on significance of anthocyanin; no conclusion 

 reached. p. 20

A suggestion that anthocyanin in the under surface of 

 the leaf increases the capacity of the leaf for absorbing 

 warmth from the ground.

coloracion rojiza de ciertas hepaticas,' Boletin de la 'Sociedad

Pigment (? anthocyanin) in certain species of Liver- 

 worts. It is developed on under surfaces, which roll over, 

 and protects thallus from undue exposure to the more 

 refrangible rays of sunlight.
