hairs, and is also protected by the crowding of the leaves 

 and the stipules. The latter are narrowly linear or seta- 

 ceous and caducous, i.e., falling early. The axillary bud 

 is entirely protected by the swollen, fleshy base of the 

 petiole. The resting bud remains very small during 

 winter, and consists of leaves 

 and stipules, crowded together, 

 and densely covered with short, 

 brown hairs. 



In Citharexylum quadran- 

 gulare (fig. 114), belonging to 

 the Verbenacece, an exstipulate 

 family, the axillary buds 

 are completely covered by the 

 concave pedestal.

with one another. The leaves attain some size before 

 expanding, and each pair covers the next younger pair. 

 In some cases the petiole forms a regular arch over 

 the bud, as, for instance, in Elius glabra (fig. 115). Addi- 

 tional protection is also afforded by hairs, both on the 

 bud and on the under side of the cup formed by the 

 petiole.
