THE AM ERICA X XA T LIRA LIST. [Vol. XXXVII. 



dons are comparatively large, green and fleshy, with a peculiar 

 one-sided appearance. The leaves are alternate, the first nep- 

 ionic leaf having three leaflets, the second five. In some cases 

 the third leaf had five leaflets like the second leaf and in other 

 cases seven, the greater number having five. This shows as 

 noted in the previous paper (Studies of Localized Stages of 

 Growth in some Common New England Plants," Amer. Nat., 

 Vol. 36, No. 431.) a difference in acceleration of development in 

 individual seedlings. An interesting feature of the leaves is the 

 fact, as was mentioned in the preceding paper, that the tip of the 

 later leaves repeats the form of the tip of the first leaf. In look- 

 ing over the figures of this plant it will be noticed that the tips 

 of all the leaves do not correspond as shown especially in Fig. 4. 

 This seems at first sight an exception to the principle of local- 

 ized repetition, but on careful study was seen to be due to the 



following growth . The fi rst 

 few leaves seem to have a 

 further development after 

 unfolding. At first the tip 

 is as given in Figs. 2, 3, 

 and 5. Then later the tip 

 broadens and becomes dis- 

 tally notched. This is seen 

 also in the seedling, when 

 the leaf unfolds the tips 

 being pointed but after- 

 ward becoming reentrant 

 as noted in Fig. 4. The 

 first leaves of seedling and
