Habitat in Galliae littore Atlantico et Mediterraneo, in Lusitania, in Hispania prsesertim in Estrema- 
dura, in Italia superiore, Apenninis borealibus et centralibus. 
A large tree reaching about 6o feet in height, and usually pyramidal and with a conical top. The 
bark of the trunk is coarse and deeply furrowed. The branches are verticillate and erebt. The leaves in 
twos [fig. i], of a rather bright and 
pleasant green, reaching from 6 or 
8 inches to even a foot in length, 
thick, long, firm, and rigid, usually 
without any waving or twisting, 
slightly serrated on the margins, 
and with numerous rows of stomata both on the back and inner side, but 
varying according to size, rather more frequent on the back than on the 
inner side, the relative numbers being about a fifth more on the back, 
[figs. 2 and 3]. For example, a fine full-grown leaf shewed twenty-five rows 
on the back, and nineteen 
on the inner side; and a smaller less - developed leaf 
from another tree gave fifteen on the back to twelve on the 
inner side. The sheath of the leaf is short and blackish, 
from l to l of an inch in length. The buds are large, thick, 
and vigorous, cylindrical, with a conical apex as much as \ of 
an inch long, and f an inch broad, with strong scales curled 
back, white and woolly, and free from resin. Figs. 4 and 5 
shew them in the younger stage, fig. 6 when more advanced, 
and accompanied by young cones. These scales furnish 
a ready and easy 
character for distin¬ 
guishing this spe¬ 
cies from almost 
every other. The 
branchlets are covered with the scars or corticaceous remains of 
former scales, as shewn in fig. 7. The male catkins grow around 
the shoot of the current year [see fig. 8], and as the shoot 
extends they become further separated from each other. They 
are usually numerous, occupying, 
by the time they reach maturity, a 
space of 6 or more inches in length. 
When they drop off, of course they 
leave a bare space intermediate be¬ 
tween the leafy termination of last 
year’s shoot, and the leafy termination of the current year’s shoot, which gives 
the foliage of the tree something of a patchy aspebt, in which tufts of foliage 
and bare places alternate like some of the tufty American species of Taeda. 
This arises in a great measure from the length of the leaves, and the extent 
of space occupied by the numerous catkins. A single male catkin magnified 
is shewn in fig. 9. The anthers [figs. 10 and 11, magnified] are as usual bilocular, and the crest is rounded, 
and thin at the edge, but very slightly lacerated. The female catkins [figs. 12 and 6] grow around the cen¬ 
tral bud at the apex of the current year’s shoot, which pushes on and leaves them behind it at its base.
