(Botan. Zeit., 1880, and now published separately.) —The relations 
of the shape of the chlorophyll-grain to the form of the starch 
granules produced therein, are explained at some length, and the 
differences in the form are shown to be dependent upon the direc- 
tion of the supply of nutritive material. Since the location and 
the course of the material from which the starch of the chloro-

(sometimes spindle-shaped). Under the influence of light these 
bodies may be converted into chlorophyll granules. ‘hey are 
presumably identical with the bodies termed by Negeli “ Brut- 
blaschen,’ and which were also noticed by Trécul.. The different 
forms of these starch-producing bodies and the characteristic 
shapes which the deposits assume, are conveniently classified. 
The author holds a view which must steadily gain ground ; 
namely, that the starch which occurs in chlorophyll granules is
