BUDS AND STIPULES. 229 
The above description was taken from a medium-sized lateral 
bud. Others show some variation in the number of whorls 
of scales previous to the true leaves; and there is also some 
variation in shape, but only of minor importance. I did not 
detect the three-lobed character to be seen in the very largest of 
the adult leaves. The lobes seem to develop after the leaves 
attalu some size. 
In Tecoma grandiflora, Delaun., the petiole is semiterete, 
grooved above, dilated at the base, and connected at the base by 
a slightly elevated ridge, which is furnished with a fringe of hairs, 
readily becoming disarticulated. 
Terminal bud in the resting stage covered by about four de- 
cussating pairs of broadly triangular scales, which evidently con- 
sist of a reduced leaf; all are more or less pointed, but the inner 
ones elongate considerably upon the resumption of growth, and 
their points are more or less furnished with teeth or serratures 
foreshadowing the leaflets of the perfectly developed leaves. 
The leaves of the growing bud are compactly folded face to face, 
so that the midrib and the secondary ones or midribs of the 
leaflets are the first portions to become exposed. The leaf, 
as a whole, attains a large size before the leaflets unfold. 
Axillary buds are sheltered by the broad petioles, by a fringe 
of hairs in front of the latter, and by their own scales. 
The use of the fringe of hairs connecting the base of the 
leaflets, and also the base of petioles, is not very obvious. They 
may render additional protection in the bud stage.

succession. "
