248 TAXACEE 
(1) The Torreyas have two very distinct grooves 
on the under-side of the ae The Cephalo- 
taxi have not. 
(2) The Torreyas have -two ieee narrow 
lines of stomata upon the lower surface of 
the leaves, that do not occupy much more 
space than the impression of .a pointed 
pencil across a piece of paper. The Cepha- 
lotaxi have two broad lines of stomata. ° 
(3) The bud seales of the Torreyas stick out in 
pairs at right angles, and bud scale marks 
are noticeable at the base of leaves. The 
buds of the Cephalotaxi are composed of 
overlapping scales (imbricated), and there 
are no bud scars visible on the branch- 
lets. 
(4) The colour of leaf of the Torreyas is a dark, 
lustrous, shining green, and gives the 
impression of having been glazed or varn- 
ished. The tip of the leaf of a Torreya 
is long and spiny, while the. tip of the 
Cephalotaxus has a shorter pointed apex. 
(5) Another marked difference is the way in 
which the long bayonet-shaped leaves of 
the Torreyas point forward towards the 
end of the branchlet. 
We have, then, called in to the assistance of identifi- 
cation five points in particular: (1) the grooves, 
(2) the thin rows of stomata, (3) the buds and bud 
scars, (4) the glossy colour of leaves, and (5) their 
forward pointing direction ; and to these we might 
have added the colour of the branchlets, which on 
new shoots are a bright green and on last year’s 
shoots a rich red. 
Wehave compared them side byside withthe Cephalo- 
taxi, but the Abies Bracteata and the Keteleerias have 
both been dragged into the maelstrom of similarities,
