BUDS AND STIPULES. 205 
as the interior of the sheath, seem intended as a protection as 
much against drought and heat as against cold. 
The lateral buds are similar, and entirely covered by the 
sheaths till they attain a large size. 
TREMANDRES. 
Platytheca gallioides, Steetz, is curiously like a Galium. The 
leaves are verticillate in decussating whorls of 8-11, linear, or 
acicular, revolute at the margin, sessile, thinly pubescent, slightly 
scabrid, articulate, persistent. 
The terminal bud consists of numerous whorls of leaves 
graduated in size. The two outer have openings between them, 
but the third whorl is conical and close, the leaves fitting to one 
another pretty closely. There is, however, a subulate tuft of 
hairs between every two leaves. 
Axillary buds few to each node, generally only one or two or 
none ; when there are two, one is a flower-, the other a leaf-bud. 
They arise and partly elongate while still within the leaves, 
forming the terminal bud. The bases of the Jeaves are erect 
or ascending even after the lamina is horizontal, and they, 
together with the interpetiolar tufts of hairs, lend additional 
Protection. The first whorl generally or often consists of eight 
leaves, and the first internode and the leaves themselves attain 
considerable length before expansion. 
DIPTEROCARPES. 
Shorea robusta, Gertn.—The stipules are linear-oblong in bud, 
lengthening with the growth of the bud, and becoming linear, 
faleate, concave over the bud, enclosing their own leaf; the 
mater part of the younger ones is furnished with an elevated 
ridge on the inner face, though not central, covered externally 
with short stellate hairs, caducous. 
Theterminal bud consists of small conduplicate leavescompletely 
mod by one or two pairs of stipules; the latter are inserted 
€ stem and partly on the base of the petiole, so that they 
overlap their own le af. 
um are three buds, superposed. The middle one is the first 
" cvelop, and is already well advanced while still protected by 
“apules of the terminal bud. A few of the lower leaves are 
in we to their stipules, or, if the leaf is present, it is small, 
Perteet and caducous. Two pairs of stipules are necessary to
