top of the bud, which in the resting stage is extremely short, as 
in Robinia Pseud-Acacia. The axillary buds are minute, evi- 
dently seldom developed, as the plant is of stout habit and very 
little branched, resting in a small cavity of the axis, and partly 
surrounded by the base of the thick petiole. 
Cedrela sinensis, Juss.—The winter-bud is protected by four 
or five modified leaves, the first two of which do not elongate 
very much in spring, while the others become green, but fleshy 
and scarcely foliaceous. All five are broadly triangular and 
entire or slightly emarginate, or the fifth may have rudimentary 
leaflets. These are followed by two perfect pinnate leaves, which 
have broadly dilated bases with no trace of an axillary bud in 
the axil of either. Succeeding ones have a small axillary bud 
that is already well developed while the leaf is still quite young 
and unexpanded. This bud is protected to a great extent by an 
open cavity at the base of the petiole, as in Rhus semialata, Murr., 
R. japonica var. Osbeckii, R. Cotinus, Linn., and others. The bud 
likewise remains very small till the following spring. 
The terminal bud is protected mainly by the broad bases of the 
petioles, which remain erect till the lamina has attained some 
size. It dies in winter, or is continued in spring with some dif_i- 
culty, and is always later in commencing to develop than the 
lateral ones. 
In Chloroxylon Swietenia, Linn., the paripinnate petiolate 
leaves are exstipulate, glabrous, persistent ; leaflets in numerous 
pairs, small, oblong, entire, obliquely cut away on the posterior 
side towards the base; petiole slender, subterete, convex above, 
dilated and thickened at the base, thinly scurfy or pubescent, 
articulated with the stem, and green, while all beneath the arti- 
culation is brown. 
The conical terminal bud is covered by three or more subulate, 
succulent, green and pointed scales ; in any case three scales cover 
all the younger members, and some additional protection is 
afforded by the base of one or two of the last-developed leaves. 
The axillary buds are very small, covered by two or more scales 
and closely protected by the dilated base of the petiole. During 
winter many of the leaves fall, leaving the buds unprotected 
otherwise than by the scales.
