had ceased producing new leaves. Several species of oaks had 
already developed far enough to show terminal buds on many 
trees while on others the leaves had not yet begun to make their 
appearance. 
Quercus nigra furnished a good example of a plant which has 
most of the nodes for next year’s growth already indicated in the 
bud. The stipules of 14 leaves showed distinctly that they had 
formed part of the scaly bud during the winter, and this was, not 
improbably, also true of most of the stipules farther up. It is evi- 
dent therefore, that the growth of the new crop of branches was little 
more than the development of the leaves whose position was 
already determined in the winter bud. Many beeches, Fagus, 
ferruginea, had formed their terminal buds, although these were 
still very small and did not at all resemble the winter buds. 
Regarding the early development of terminal scaly buds it may 
be observed that at the time of their detection they are far from 
being fully developed, and they are often still very dissimilar from 
their fully grown winter form. Moreover at the time of their first 
detection the internodes of the new year’s twigs have not yet fin- 
ished their growth, so that the terminal bud is already indicated 
at a time when the full length of the twig has not yet. been at- 
tained. 
Vaccinium tenellum at the end of March was shedding the tiny 
tips of the branches consisting of two or three very minute leaves. 
Carpinus Virginiana was shedding tips about 3 mm. long, some- 
times longer, of which the leaf elements could be recognized more 
readily. Although the old branches of Leucothoe axillaris gave 
evidence that they had shed their tips during the preceding year, 
the new crop of branches had scarcely started in March. 
Both methods of terminating the growth of the year, that by 
means of the formation of terminal scaly buds, and that of casting 
off the tips of branches, are employed very early in the year, as 
just seen. When, however, a ligneous plant does not terminate 
its growth until late in the year, the casting off of the tips of the 
branches seems to be the rule, where killing back of the tips does 
not obtain. It would be interesting to learn how many ligneous 
‘plants develop terminal scaly buds after the first of June, for ex- 
ample, in a more northern climate. It is believed that the casting
