and more efpecially the fcale, feed, and wing, larger. The latter, as well as the brad at the back of the 
fcale, are differently fhaped. 
This fpecies is allied to A. Pattoniana , and by fome has been fupposed to be fynonymous with it. 
Mr Gordon fo reckons it in his “ Pinetum,” but the two trees are perfectly diftindt, and may be readily 
diftinguifhed from each other. A. Pattoniana is a tree which grows to nearly double the height of 
A. Hookeriana, the former reaching 150 feet, the latter only from 50 to 100 feet. The cones do not differ 
much in fize, but thofe of A . Pattoniana when ripe are of a dark-brown colour, and thofe of A . Hookeriana 
of a lio-ht-fawn colour, somewhat of the hue of the cone of A. alba. The fcales of A. Pattoniana are a 
third or a half fmaller than thofe of A. Hookeriana. They are deeply crenulated quite down to the fpace 
covered by the brad, and that place is fmooth and prominent, as fhewn in the woodcuts [figs. 4 and 5], 
reprefenting refpedively the outer and inner fide of the fcale of 
A. Pattoniana. The fcales of A. Hookeriana are not crenulated, 
an evanefcent raifed line only fhewing itfelf here and there. The 
fhape of its fcale alfo is lefs regular; it is ufually more cut out on 
one fide than the other, and where the cutting out has commenced, 
the fcale has thinned off fo as to be membranaceous ; figs. 6 and 7 reprefent the outer and inner fides. 
In A. Pattoniana it is not fo thinned off. In the fcale of that fpecies the place where the two next fcales 
have lain over it, is not, or at leaf! is fcarcely, to be diftinguished from the expofed part. In A. Hookeriana 
it is very marked, there being an immediate rifing or thickening in the line of the fcale juft beyond where 
the overlapping fcales lay, fhewing the expofed part very diftinctly of a triangular fhape, with its fides 
concavely curved. The furface of the covered part in A. Hookeriana is duller and more opaque than the 
expofed part, and the ftreaks or raifed lines are lefs perceptible. In A. Pattoniana no fuch difference 
exifts. The brad! in A. Pattoniana contracts at about two-thirds of its

length from the top, and has a projecting purple ear immediately before the 
contraction, as feen in fig. 8. A. Hookeriana has no fuch ear, and the 
contraction takes place at one-third from the top inftead of two-thirds 
[fee fig. 9]. The ear fpoken of is not to be confounded with a fort of projection which both have at the 
top angles. The feed and the wing of A. Pattoniana [fig. 10] are both about one-third ftiorter than thofe 
of A. Hookeriana [fig. 11 ], and the wing of the former has a purplifh-brown tinge at the top and back, which 
is not in the latter. The leaf is generally fmaller, although 
fometimes as large as that of A. Pattoniana ; and although on a 
curfory glance it looks very like, it ftill differs fo effentially from 
it as of itfelf to eftablifh beyond all doubt that they do not belong 
to the fame fpecies. A. Hookeriana has ftomata on both fides 
of the leaf; A. Pattoniana has them only on the under fide. 
The former has the ftomata normally arranged in four rows, 
with the ufual interruptions and aberrations; in the latter they 
are fmaller in fize, arranged more clofely, leaving a wider outer 
margin without ftomata, and normally in five rows inftead of 
four. The former has the margin of the leaf fmooth ; the latter 
has it diftinCtly ferrated towards the point. The differences

woodcuts, which are taken from leaves purpofely chofen of the fame fize. Had they been chofen of the 
more ordinary proportions, the differences between them would have been ftill more apparent. F igs. 12 and
