part. A few secondary roots of a stouter and more vigorous 

 nature were produced in many of the larger growing species, 

 which may be compared in appearance with runners, but 

 which had not developed sufficiently to allow a definite 

 opinion being formed as to their nature. 



General Habit of Various Seedlings. 



A most evident distinction may be drawn amongst such a 

 collection of young seedlings as we have undertaken to 

 examine, based upon their general habit. 



Of the several species which produced healthy seedlings 

 before the 120th day, the following may be characterised as
