where as Pattoniana, but in Edinburgh called Hookeriana — that with the angular leaves — abounds, with larger or 
smaller purple, or sometimes green cones. On the northern mountains only, and not in California, and where the 
Edinburgh A, Pattoniana with flat leaves is said to come from, Tsuga Mertensiana climbs up to the same altitude as 
the other, — smaller there, but otherwise undistinguishable from the seaside form. Now the leaf anatomy of the tree 
in the Edinburgh Botanical Garden, raised from Jeffrey’s seeds, and cultivated there as Abies Pattoniana, is that of a 
true Tsuga, and cannot be distinguished from that of 7. Mertensiana, as .the figure of Prof. McNab in Proc. Roy. Irish 
, vol. ii., pl. 23, fig. 2, under the name of Pinus Pattoniana, shows, and as I have myself found it in examining 
the Edinburgh specimen ; but the original figure in the so-called Oregon Committee’s Report is that of the pein 
leaved tree called there A. Pattoniana, and now generally known by this name, or sometimes as A. Williamsoni. Now. 
is not the flat-leaved tree called in Edinburgh A. Pattoniana, the mountain form of Tsuga Mertensiana? This I ting 
gest as a plain solution of the difficulty. The only objection seems to lie in the reported size of the cones of this 
species, which are said to be nearly of the 
size of what we now call Pattoniana, and 
much larger than those of Mertensiana ; 
but may there not be some error or confu- 
sion about these cones ? At all events, I 
cannot distinguish the Edinburgh A. Pat- “ 
toniana from T. Mertensiana, nor the small 
mountain form from the colossal seaside 
trees of this species, and I find no third 
species. —[Jan. 4 1882, n. s., vol. xvii.] 
PINUS LATISQUAMA,”. sp., I name [712] 
an interesting new pine, discovered 
. E. Palmer in 1880, in the mountains 
south of Saltillo, Mexico. It belongs to 
the Pinasters with peripheral ducts in the 
leaves and with subterminal cones. The 
short (14 to 2 inches long) extremely slen- 
sia — slightly serrulate leaves are in

prickle; the lowest scales of the cone have 
the form of reflexed tubercles ; the seeds apparently large and wingless (fig. 125, p. 713). 
This species, about the habit, bark, and timber of which nothing further is known, has very peculiar alliances. 
The foliage and its sheaths, and the position and the peduncle of the cone, would make it a Strobus, if the form of the 
cone-scales did not constitute it undeniably a Pinaster ; it is evidently most nearly allied to the cembroid or Nut-Pines, 
but recedes from them by the leaves sted serrulate and the cone-scales being without those bosses which are so promi- 
nent in the true Nut-Pines. The leaves are among the thinnest pine-leaves known, scarcely one-third line wide; they 
have two very small vetiptaand ar on the dorsal side, separated from the epidermis only by the simple layer of 
hypoderm cells which underlie the epidermis all around the leaf. The cone here figured (fig. 125), was 3} inches long, 
and 1? inches in diameter when closed, its peduncle $ inch long. The scales were arranged in $? order: the middle ones 
are unusually wide for the size of the cone, 1 inch or more b . Seeds were not seen, but the cavity of the scale 
shows that they are probably } inch long or over, and destitute of a wing. — [Dec. 2, 1882, n. 8. vol. xviii.] 
Pinus contorta. — The figure of Pinus contorta at p. 45 most probably represents the broad-leaved P. [351] 
Murrayana, which is a large tree with tall trunk 3 feet in diameter in the sierras, 1-14 foot in the Rocky Moun- 
tains; but young trees will, of course, remain bushy, clothed with branches to the base. The wood is soft and white, 
like spruce wood more than any other pine wood I know ; and if there is any specific character in the wood structure
