XXVIII. — On the Development of Starch and Chlorophylle 

 Granules. By Carl Nageli*. 



In the actual puncfum vegetationis there is nothing but a homo- 

 geneous mucilage (protoplasma of Mohl). This becomes finely 

 granular in the lower part ; it is here that the deposition of the 

 fibres occurs. If we examine the fluid of the cell from this part 

 (the fibre zone) of a young leaf or stem, we find in it very small 

 granules, the diameter of which does not exceed '003 of a line, 

 and in these consequently nothing is to be made out. In the 

 vicinity are cellules or utricles of from '001 to '0025 of a line ; 

 they are filled with a thin yellowish mucilage, which, in the smaller 

 appears homogeneous, in the larger finely granular. Somewhat 

 lower down (the starch zone) the formation of amylum takes place ; 

 the young leaf there becomes of a shining white colour. The cell-
