[As supplementary to the above interesting observations on the 
rapid growth of Bambusa in the East Indies, we may here mention that 
the same plant in the stove of the Royal Botanie Garden of Glasgow, 
has been ascertained to rise one foot in twenty-four hours. The leaf of 
Urania speciosa has been found by Muller to lengthen at the rate of 
from one and a half to three and a half lines per hour, and as much as 
from four to five inches per day. But the most remarkable instance of 
this sort, says Dr. Lindley, is stated by Junghuns, who has known the 
allich informs us that there is a mistake here. The girth (three feet above 
the base) and the number of joints have reference to the 1st of July. 
+ This was four feet high on the 24th of June. On the 1st of July it had a circum. 
ference of 4.75”, with about twenty joints and scales.
