(Rhus hirta; R. typhina of Gray) Sumac family
Flowers - Greenish or yellowish white, very small, usually
5-parted, and borne in dense upright, terminal, pyramidal
clusters. Stem: A shrub or small tree, 6 to 40 ft. high, the ends
of branches forked somewhat
like a stag's horns. Leaves.
Compounded of 11 to 31 lance-shaped, saw-edged leaflets, dark
green above, pale below; the petioles and twigs often
velvety-hairy. Fruit: Small globules, very thickly covered with
crimson hairs.
Preferred Habitat - Dry, rough or rocky places, banks, roadsides.
Flowering Season - June.
Distribution - Nova Scotia to Georgia, and westward 1500 miles.
Painted with glorious scarlet, crimson, and gold, the autumnal
foliage of the sumacs, and even the fruit, so far eclipse their
inconspicuous flowers in attractiveness that one quite ignores
them. Not so the small, short-tongued bees (chiefly Andrenidae)
and flies (Dipteria) seeking the freely exposed nectar secreted
in five orange-colored glands in the shallow little cups. As some
of the flowers are staminate and some pistillate, although others
show a tendency to revert to the perfect condition of their
ancestors, it behooves them to entertain their little
pollen-carrying visitors generously, otherwise no seed can
possibly be set. And how the autumnal landscape would suffer from
the loss of the decorative, dark-red, velvety panicles! Beware
only of the poison sumac's deadly, round grayish-white berries.
Most sumacs contain more or less tannin in their bark and leaves,
that are therefore eagerly sought by agents for the leather
merchants. The beautiful SMOKE or MIST TREE (R. cotinus),
commonly imported from southern Europe to adorn our lawns
(although a similar species grows wild in the Southwest), serves
a more utilitarian purpose in supplying commerce with a rich
orange-yellow dye-wood known as young fustic. All this tribe of
shrubs and trees contain resinous, milky juice, drying dark like
varnish, which in a Japanese species is transformed by the clever
native artisans into their famous lacquer. With a commercial
instinct worthy of the Hebrew, they guard this process as a
national secret.
The SMOOTH, UPLAND, or SCARLET SUMAC (R. glabra), similar to the
staghorn, but lacking its velvety down, and usually of much lower
growth, is the very common and widely distributed shrub of dry
roadsides, railroad banks, and barren fields. Another
low-growing, but more or less downy upland sumac, the DWARF,
BLACK, or MOUNTAIN SUMAC (R. copallina), may be known by its
dark, glossy green foliage, pale on the underside, and by the
broadening of the stem into wings between the leaflets. Hungry
migrating birds alight to feast on the harmless acid red fruit
when the gorgeous autumnal foliage illuminates their route
southward. But while they are, of course, the natural agents for
distributing the plants over the country, men find that by
cutting bits of any sumac root and planting them in good garden
soil, strong specimens are secured within a year. An exquisite
cut-leaved variety of the smooth sumac adorns many fine lawns.
Everyone should know the POISON SUMAC (R. Vernix - R. venenata of
Gray) as the shrub above all others to avoid. Like its cousin,
the POISON or THREE-LEAVED IVY (R. radicans), which once had the
specific name Toxicodendron, although Linnaeus applied that title
to a hairy shrub of the Southern States, the poison sumac causes
most painful swelling and irritation to the skin of some people,
though they do nothing more than pass it by when the wind is
blowing over it. Others may handle both these plants with
impunity. In spring they are especially noisome; but when the
pores of the skin are opened by perspiration, people who are at
all sensitive should give them a wide berth at any season.
Usually the poison sumac grows in wet or swampy ground; its bark
is gray, its leaf-stalks are red; the leaves are compounded, of
fewer leaflets than those of the innocent sumacs - that is, of
from seven to thirteen - which are green on both sides; the
flowers, which are dull whitish-green, grow in loose panicles
from the axils of the leaves, and naturally the berries follow
them in the same unusual situation. "By their fruits ye shall
know them:" all the harmless sumacs have red fruit clusters at
the ends of the branches, whereas both the poison sumac's and the
poison ivy's axillary clusters are dull grayish-white.
