BUDS AND STIPULES. 231 
numerous leaves convolute round one another and exuding a 
resinous fluid, by which they are rendered viscid or gummy. 
The outermost leaf would cover the whole of the upper part of 
the bud, but only two-thirds of it below the middle; a second 
leaf covers the greater portion of that left exposed by the first ; 
and the three succeeding ones show their petiole or a portion of 
it only. Therefore, although one leaf covers the greater part of 
the long tapering bud, five are necessary to completely cover it. 
Axillary buds arise in the axils of leaves that are still quite 
young. They are then covered by the petiole, which is more or 
less erect at this stage. The first leaves, like the rest, are 
glandular and gummy, and must afford a considerable amount of 
protection. 
VERBENACES. 
The Verbenaceæ are exstipulate. 
Citharezylum quadrangulare, Jacq. (fig. 40).—The axillary buds 
are completely covered by the concave and tongued pedestal.
