Africa. The karree boom of southwestern Transvaal and adjacent
Bechuanaland. Valuable hardwood tree with odd-pinnate
leaves; for regions of limited rainfall, 10 to 15 inches in winter.
Fruits are edible. Can be grown from poles in same manner as

in the mountains near Kwanyintang, Shensi, China. Tall shrub or
sometimes tree, 60 feet high. Foliage brilliant in fall. A gall insect
produces large, inflated galls, called "gall nuts," utilized extensively
for black dye, great quantities being exported from Hankow. Cultivation
on cheap land might be attempted. Has weedy tendencies.

RHUS VERNICIFLUA. Lacquer tree. Poisonous to handle.
(Antidote, weak alcoholic tincture lead acetate.) Tree 25 to 40 feet

bark, the famous lacquer manufacture is one of the important industries
in Japan and China. The tree is deciduous and stands considerable
frost.

Los Angeles, Cal. Showy ornamental shrub, up to 12 feet in
height, with fuchsialike bright-red flowers. Said to be evergreen,
but is reported to be deciduous and dormant during the dry season
at Los Angeles. When the rains set in the new foliage appears —
rich, glossy, dark green — soon followed by the bright flowers, pendent
all along the stems of the previous year's growth.
