Description.—K tree with a spreading top, varying in size according to situation, reaching 50 feet high,
with a trunk 1 foot in diameter, down to a shrub 3 feet high. High up on the mountains it diminishes
until it almost creeps along the ground, with a tabular top so compact that a person can walk on it. The
bark of the trunk is as white as milk, but moderately rough and thin, having (according to Dr, Newberr>-)
much the appearance of the bark of the White Oak {Qucrcus alba) in trees of moderate size. Tlie bark
of the branches is loose, spong}-, grey, smooth, and tender; the wood of the branches very flexible and
tough. The leaves (fig, I ) are densely crowded together, confined to the extremities of the branches,
five in a sheath, but sometimes fewer (two, three, or four), pale bluish-green, triangular and smooth, those
of each fascicle of uniform length and approxiinatcd, giving the foliage a notched or cropped look ;
they are subserrated, the serrations being at long distances from each other. Beneath the epiderm is a
thick layer of hypodcrm, which is extended round cach of the three sub-epidermal resin-canals (fig, 2),
