63.—WESTERN SUGAR-BERRY. HACK BERRY. PALO BLANCO. (Cel. 
tis occidentalis, Linn., var. reticulata.) 
A rather small tree, usually growing along streams in high mountain 
canyons, or in less favorable situations reduced to a shrub. It occurs 
fiom the mountains of southern Arizona through the Rocky Mountains 
to eastern Oregon; sometimes 30 feet high, with a trunk 18 inches ip 
diameter, but Postly with a short, thick trunk, and branching near 
the onan thus furnishing buat little good cee although the latter 1s 
sound, heavy, bard, and desirable for turnery. The wood is not gener- 
ally distinguishable fiom that of the type which is found farther east. 
Description.—Leaves thickish, 1 to 2} inches long and 2 to 14 inches wide, mostly 
heart-shaped, with an acute apex, sometimes ovate tance! -shaped; base often with 
unequal sides (oblique); margin entire or sharply toothed; upper surface rough, with 
fine, sharp teeth pointing toward the apex; usually with soft pubescence below or 
roughish on the veins, which are peculiarly joined into a net-work (rcticulate). 
Truit globular, cherry-like, reddish-yellow (purple with age), + of an inch in diameter, 
with large stone and scanty flesh (sweetish); on slender stems, + to $ of an inch long 
from axils of leaves, Young shoots hairy. Resembles an Eln in its general appear- 
wuce. 
64. MEXICAN MULBERRY. (Morus microphylla, Buckley.) 
A small tree, sometimes 20 to 25 feet high and 6 to 10 inches in di- 
ameter, or reduced to ashrub. It ocecurs most commonly in the mount- 
ain canyons of southern New Mexico, where it probably attains its 
largest size (also in western Texas and Mexice). The wood is hard 
and heavy, but of little use, except for fuel as the trunks are generally 
much distorted, flattened, and twisted. 
Description.—Leaves small, 1 to 1? inches long, $ to 1 inch wide, ovate-heart-shaped, 
sbarp- pointed, margin sharply toothed; rough, with short bristly hairs above and 
below; leaf-stems and young shoots velvety. P ruit small, often sweet and pleasant. 
Bark much broken, except in young trees. Milky juice exudes from a freshwound. ° 
PLATANACE®: PLANE-TREE FAMILY. 
65.—SYCAMORE. (Platanus Wrightit, Watson.) 
A middle. sized tree, 40 to 60 feet in height and 1 to 2 feet in diameter, 
abundant in the mountain canyons of southwestern New Mexico, and 
in some localities being the predominant species (it occurs also in 
southeastern Arizona and in Mexico). The wood is light, soft, and 
brittle. 
Description.—Leaves alternate, rounded in outline, 5 to 7 inches broad, deeply cut 
into 3 to 7 (chiefly 5) sharp-pointed lobes; usually a deep sinus at the base; young 
shoots and leaves densely clothed above and below with a velvety down, whieh is 
more or less persistent with age. The seeds are packed in aspherical head—“ ball”— 
which is 3 of an inch in diameter, 3 to 5 of these balls borne on a long pendent stem. — 
The trunks are often crooked and more winding than other species of Platanus.
