214 SIR JOHN LUBBOCK ON 
The scales are followed by normal leaves. Each segment of 
the leaf is conduplicate, and the midribs of the first, as well as 
the petiole and the internodes, are further protected by a thick 
felt, which is sometimes of a rich orange colour. This becomes 
less developed on the inner leaves, where it would not be so 
much wanted. 
ACERINER. 
Acer platanoides, Linn. (Norway Maple).—The scales covering 
the bud (fig. 11) are, like the leaves, opposite and decussate. They 
represent the bases of leaves. The outer ones have a black tip 
which is sometimes trifid at the tip (fig.11), representing the leaf, 
Fig. 11.

sometimes expanded mto a small leaf. There are from four to 
six pairs gradually inereasing in length, and in many easet 
(PI. 13. figs. 2, 3, 4) becoming pink. The upper pair show minute 
points at the tip—the rudiments ofa leaf. They arch very prettily 
over the true leaves, showing a marked contrast both in form an 
colour. The leaves are green, and the petiole is narrow an 
round. The buds are not only protected by closely-fitting scales 
but also by being somewhat sticky. 
The outer scales are not dead, but increase in length, often 
considerably (Pl. 13. figs. 2, 3), and arch over the young leaves. 
Some trees have a tendency to develop small leaves at the tips 
(PI. 13. fig. 4). 
SABIACES. 
The Sabiacee are exstipulate. In Meliosma pungens, Wall.
