LXXVII. CONI’FERE: PI‘NUS. 975 
the P. mitis of Michaux; being without the 
violet-coloured glaucous bloom on the young 
shoots ; having rigid leaves, generally in threes ; 
and a cone with very strong prickles, like that of 
P. Tee‘da, to which species we have referred it. 
The only plants that we know which answer to 
Michaux’s description of P. mitis are at Drop- 
more, where they are readily known by the violet- 
coloured glaucous bloom on the young shoots, 
and by the leaves being almost all in twos; at 
the same time, it is proper to mention that the 
leaves there, though soft and slender, are much 
shorter than those in Michaux’s figure. The 
name applied to this species at Dropmore is P. 
variabilis. There is also a plant at Dropmore 
named P. mitis; but it is wholly with three ; 
leaves ; and, as far as we can ascertain (the 1813. P. mitis. 
tree not having yet borne cones), it belongs 
either to P. serétina, or to some variety of it. The description given 
by Miller of P. echinata, as having finely elongated leaves, and a cone with 
very slight slender prickles, agrees perfectly well with this species, as described 
by Michaux ; and not at all with Mr. Lambert’s P. variabilis, which he de- 
scribes as having leaves only 2in. long, and cones with scales having “ thorny 
points of a strong woody texture projecting from them.” 
£16. P. conro’rta Douglas. The twisted-branched Pine. 
Buds roundish, with a blunt point, covered with resin, and brown. Leaves 
2 in a sheath, 2 in. long ; sheath very short, imbricated, black. Cones from 
2in. to 24 in. long; and from 3 in. to 1 in. broad ; scales with the apices having 
a depressed lateral rib, termi- 
nating in a blunt point, fur- 
nished with a caducous mucro. 
The shoots are regularly and 
closely covered with leaves, 
much in the same manner as 
those of P. (s) pumilio, to 
which the specimen sent home 
., by Douglas, in the Herticul- 
tural Society's herbarium, 
bears a general resemblance. 
This pine was found by 
Douglas in North-west Ame- 
rica, on swampy ground near 
the sea coast; and, abun- 
dantly, near Cape Disap- 1815. P. contérta. 
pointment and Cape Lookout. 
Fig. 1814. to our usual scale, and jig. 1815. of the natural size, are from 
the specimens in the Horticultural Society’s herbarium. 
1814, P. contorta. 
2 17. P. rursina ta Bosc. The Top-shaped-coned Pine. 
Leaves 2 in a sheath, slightly glaucous, scarcely lin. long. The buds 
are very small, reddish, fringed, and not resinous. The cones are in whorls 
from 2 to 5 together, sharply pointed, longer than the leaves, with the scales 
almost square, and not pyramidal. Bosc thinks that it is probably a native 
of North America; but his description is taken from a tree in the garden of 
the Petit Trianon, about 40 ft. high, the only one he had seen. He adds that 
its general appearance resembles that of ?. mitis ; but it differs in its leaves 
being much shorter, and its cones being without spines.
