232 SIR JOHN LUBBOCK ON 
The terminal bud in the growing state consisting of leaves 
partly conduplicate or folded along the middle, then involute at 
the margins and placed face to face, but not overlapping or 
interlocking with one another. They attain some size before 
expanding, and each pair covers the next younger pair. 
PEDALINES. 
Craniolaria annua, Linn.—The terminal bud emerges from 
between the bases of the youngest expanded pair of leaves. 
Each succeeding pair of leaves covers the next younger pair 
completely while in bud. The edges of the younger leaves lie 
in the channel of the midrib of the older ones. 
The axillary buds in the younger stages are protected by the 
thick petiole, by glandular hairs, and more or less by the leaves 
above them, while the petiole is yet short. 
PHYTOLACCACES. 
Rivina levis, Linn.—Leaves alternate, petiolate, ovate or oblong- 
ovate, finely downy on the midrib and principal nerves, but 
particularly so beneath; petiole grooved above, slightly dilated 
at the base, with a depression or cavity there, narrowly margined, 
with the margins decurrent upon the stems, forming slightly 
elevated ridges. The ‘Genera Plantarum’ describes the stipules 
as minute and caducous, but the only organs possessed. by the 
plant and comparable to stipules are two or more conduplicate 
leaves of unequal size, and having the primary lateral nerves 
quite apparent. They are situated in front of the petiole and 
close to the sides of the axillary bud, of which they are the first 
two leaves, seemingly opposite by the internodes not being 
developed, but evidently alternate, judging by their unequal 
development. 
The terminal bud consists of numerous conduplicate leaves, 
sheltering one another to some extent. 
The axillary buds arise close to the apex of the stem while the 
leaves in whose axils they occur are quite young; at this stage 
they are sheltered in the groove of the petiole and that of the 
stem, and later on receive protection for a short time from the 
first two leaves which they develop. 
Rivina lutea, hort.—Leaves broadly ovate, and all parts of 
them, including the petioles as well as the stems, densely dow?’ 
This downy condition helps to protect both terminal and axillary
