is especially true of buds which show in section numerous scale- 

 like growths around the meristematic point. These scale-like 

 growths appear, in the unfolding bud, to be the stipules of 

 the whorl of leaves at the distal end of the young stem (figure 

 48). Since the whorl is not a true one but is produced by a 



mm.

shortening of the internodes in this part of the stem, the number 

 of leaves at the beginning of winter for this species is still a matter 

 of conjecture. Buds of Quercus rubra give stronger evidence of 

 containing the complete number of leaves in that the leaves with 

 the new terminal bud and the whorl of axillary buds are pushed 

 out and developed simultaneously, as in Poptdtts. 



From evidence accumulated from November, 1905, to May 22,
