Accessory Buds.— With Plate X7V—The axillary buds of Spiraca Sor 
bifolia L. are very conspicuous and are especially interesting because 
of the pair of large collateral accessory buds which are usually asso- 
ciated with them. There is no better plant than this for studying the | 
nature of accessory buds, if taken when these buds are just making 
their appearance, say in June or July. During the winter the thre 
buds seem to have no connection with one another, but when small 
the accessory buds are plainly seen to arise from the axils of the first 
two bud-scales of the axillary bud. (Fig. 1.) Occasionally only on 
accessory bud miakes its appearance, and sometimes when both acct> 
sory buds are present the normal axillary bud aborts and results 2 
apparently two axillary buds entirely separated from one another. — 
No other Spirea examined had accessory buds, but other specié 
belonging to the order Rosacez were examined, and wherever ag 
sory buds occurred they were collateral with the axillary buds, 
evidently axillary to the lower bud-scales. : : 
In a cultivated species of cherry some of the nodes have simple # 
illary buds while others have one or more accessory buds of equal o 
almost equal size with the axillary bud; but as between these two . 
ditions there was every degree of development present. The origin 
the accessory bud was plainly seen to be the same as those of ae 
There are no accessory buds on the wild cherry (Prunus ~ : 
Ehrh.), but on examination of the rings left by the falling of the 
scales at the beginning of this year’s growth a small bud is see? ms

Diervilla trifida Moench. gives excellent examples of this arrange bud 
of the buds (fig. 3). Here two buds appear above each a 
and in case the axillary bud is in any way destroyed, the io at 
sory on that side increases in size till it is equal to the gee a sth 
the opposite side (fig. 4). The same arrangement is also foun ji ap 
eral cultivated varieties of honeysuckle, as Lonicera Halliana a ani 
ica and var. aurea, etc., while our native honeysuckle (Z- S¥ 
Gray) has no accessory buds.
