cells, which is externally, indicated by a green stripe dividing the bands of 
stomata, so that these leaves show q lower w;hite bands. Cones 6-8 inches 
long, 2^-3^ thick, purple; bracts lanceolate, shorter than the broad scale 
(height to width as 6 : ip); wing of slender seed very oblique, wider than 
long; the only seed examined had jp cotyledons. 
Many years ago it was suggested by Mr. McNab of the Edinburgh gar¬ 
den, that nobilis and magnified might be forms of the same species; some 
seedsmen of California seem, also, to have come to this conclusion; and 
now Messrs. Hooker and Gray, who a few months ago enjoyed the oppor¬ 
tunity of examining both on their native mountains, incline to the same 
opinion; magnified would thus be the southern, short-bracted, and nobi- 
lis the northern, long-bracted form. It is quite probable that the length of 
the bracts may vary; we know it Of nobilis , but it is doubtful whether this 
could be the case to such an extent as to permit us to unite both species. 
In magnified no lengthening of the; bracts has been observed thus far, 
and iq nobilis they never, I believe, become shorter than the scale. But 
besides this, I confess, rather doubtful 'difference in the length of an or¬ 
gan of minor importance, the flatter and grooved leaves of the young 
nobilis , and the higher and proportionately narrower scales of this species, 
together with the smaller number of cotyledons (if constant), seem to indi¬ 
cate specific distinction. Further explorations must show whether mag¬ 
nified, or anything like it, grows in the regions which we know as the 
home of nobilis.
