cases. 1. The cotyledons of Pines, though colorless up to the 
moment of germination, then turn to bright green even when 
light has no access to them. Snalnth e green is certainly due to 
the formation of chlorophyll, and to its production without the 
intervention of light. This chlorophyll is here formed at the

The peculiarity is, that this chlorophyll remains for a very long
