is greatest in the basal portion, the apical portion continues to grow for 
very nearly or quite as long. The growth of the flower-stalk of Pelar- 
gonium he describes, on the other hand, as centrifugal, the growth of 
each zone ceasing before the one next above it. 
With regard to the relative amount of growth by day and by night, 
Miinter also gives no measurements, but states that in the daytime the 
plant grows at first five times, then four times, and then three times 
stronger than by night. This differs materially from the general law as 
stated by Sachs (Text-Book, English edition, page 749), that “ the plant 
will, according to circumstances, sometimes grow more quickly by day, 
sometimes by night, without exhibiting any exactly recurrent period- 
icity,” the difference, however, being never so great as that stated by 
inter. Mr. Bennett’s observations are more in accordance with this.
