vanced as the accessories of the true axillary bud. In the third node 
where the energy seems to reach a climax the terminal bud produces 
the succeeding internode and the remainder of the power is spent in 
forming and protecting a strong bud whose destiny is to develop a 
secondary axis the following season. The year’s growth never ends 
with an uncompleted series, the crowning bud always belonging to the 
third node. 
The wild grape (Vitis cordifolia Mx.) is precisely similar to Ampe 
lopsis in all these characters, but in the cultivated varieties examined 
considerable variation was found to exist in the periods of recurring 
nodal characters. The node at which the terminal bud continues 
the main axis occurred in these varieties at intervals of three, five, 
seven or even nine, and though usually at odd intervals would some- 
times occur in the fourth or sixth places. This variation is probably 
due to the unnatural conditions attendant upon cultivation, especially 
such as pruning. 
Prof. Alphonso Wood considered? the tendrils of the grape abor 
tive or transformed flower-stalks. This is not necessarily true. Both 
are axial developments arising from terminal buds and hence occupy 
similar positions, but it is no more correct to say the tendrilsare abor- 
tive flower-clusters than that the flower-clusters are modified tendrils, 
which latter would be the more probable if either were true, becaus 
tendrils are produced during the entire growing season while flower 
clusters appear for a very short interval only. 
The accessory bud of Juglans nigra L. and species of Carya is Ve 
small and arises just below the axillary bud in the groove at the bas? 
of the petiole. Observations thus far indicate that the relative pos 
tion of axillary and accessory buds forms a family character. Tho! 
Juglans cinerea L.., being rather rare in this section, has not re

regularly produced by accessory buds, their office being simply ae 
the place of the axillary bud in case that is destroyed, or normally d* 
velops into some other organ, as do the axillary buds of Dierv! 
which develops the fruit.
