GeographicalDistnhtlion.—1\iQ. range of tliis species is apparently restricted. It has been met with
on the mountains between Shasta and Scots Valley in Upper California, N. Iat. 40° 30' to 41° 50', at an
elevation of between 5000-8000 feet, and, according to Engelmann, on the head waters of King and
Kern rivers, and on Mount Whitney.

this country. Very few of these grew.

Habitat in China boreali.
A tree of moderate size; branches long, slender, little divided, glaucous, and covered with a smooth
light-grey bark, similar to that of the Weymouth Pine; rendered a little rough on the stem and older
branches by the phyllula;, which are rhomboidal. When the tree becomes older the bark peels off,
leaving the stem and branches of a white colour, whence the Chinese name. Buds not resinous, and
formed of several reddish-brown smooth-fringed scales, largest at the base, and rough at the edges.
Leaves in threes (fig. i), very stiff and strong, convex on the back, and keeled on the inner face, serrulated
on the margins, and keel 2 or 3 inches long, and thickly placed along the young shoots; frequently
in bundles towards the ends of the branches, somewhat in whorls, with stomata both on the back and on
the inner sides. On the back (fig. 2) there is one row of stomata next the margin, then a vacant space,
in which is usually a hollow line in the dried specimens. Beyond this there are two, three, or even four
rows on each side of the middle, but two or three is the commonest number. On the inner sides (fig. 3)
there is a single row near the outer margin, then a small space, then two rows
is usually raised in the dried specimens—then three more rows next the keel.
