cells, which is externally indicated by a green stripe dividing the bands of 
stomata, so that these leaves show 4 lower white bands. Cones 6-8 inches 
long, 2^-3^ thick, purple; bracts lanceolate, shorter than the broad scale 
(height to width as 6 :10); wing of slender seed very oblique, wider than 
long; the only seed examined had 10 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 oi 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 in 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 leave’s of the young 
nobilis , and the higher and proportionately narrower scalesof this species, 
together with the smaller number of cotyledons (if constant), seem to indi¬ 
cate specific distinction. Further explorations must show whether mag- 
nifica, or anything like it, grows in the regions which we know as the 
home of nobilis.
