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. AMERICAN HOLLY (Ilex opaca) Holly family Flowers - Very small, greenish or yellowish white, from 3 to 10 staminate ones in a short cyme; fertile flowers usually solitary, scattered. Stem: A small tree of very slow growth, rarely attaining any great height. Leaves: Evergreen, thick, rigid, glossy, elliptical, scalloped edged, spiny-tipped. Fruit: Round, red berries. Preferred Habitat - Moist woods and thickets. Flowering Season - April-June. Distribution - Maine to the Gulf of Mexico, west to Texas, chiefly near the coast and south of New York.
