 The direct development of the seedling shows 

 much acceleration as the first leaf of the ordi- 

 naiy seedling is considerably complex. The 

 first nepionic leaf of the seedUng of this spe- 

 cies is shown in Figure 3. It is a decidedly 

 compound leaf. The second leaf is still more 

 complex. 



The spring growth is to some degree diffi- 

 cult of investigation, as the plant starts its 

 growth very early. The first leaves seen 

 under usual conditions of growth are very 

 complex. It was therefore a matter of some 

 trouble to obtain specimens showing rever- carota. shoeing cotyie- 

 sionary characters. Finally plants growing lelves" 

 under unfavorable conditions were sought. 

 There the results were most gratifying. The. plants shown m
