92 ABIES, OR SILVER FIRS 
for a short distance and for a part of their length to 
the stem. 
\ From the A. Nordmanniana, which has a similar 
arrangement of leaves, the Amabilis is distinguished 
by its more blue colour, by its citron-like smell, and 
by its small and resinous winter buds. Then, again, 
it has no stomata on the upper side of its leaf, while 
the Nobilis and Magnifica have. The apex of leaf 
of Amabilis is notched, while of the others it is 
rounded and entire. 
GROUP IV 
A. Nositis (NOBLE Fir), AnD A. Macnirica (SHASTA, 
oR RED Fir) 
Amidst these glorious works of Thine, 
The solemn minarets of the pine 
And awful Shasta’s icy shrine, 
WHITTIER, 
The little differences between these two ought to 
be adjusted without much difficulty. 
The leaf of the A. Nobilis has only two surfaces 
and the one on the top is grooved, while the A. 
Magnifica’s leaf is quadrangular or diamond-shaped 
in section and not grooved. If taken between the 
fingers it will roll round easily, while the Nobilis, 
which is flat or two-sided, will not respond to any 
such rotary treatment. 
GROUP V 
A. CILIcIA AND NuUMIDICA 
Group V and the following Group VI seem especially 
to shine in irregularities, and to comprise a sort of 
menagerie omne-gatherum group of unorthodoxy that 
have been denied admittance elsewhere, often for 
the merest trifle,
