212 PRACTICAL FORESTRY. 



red, acid to the taste, and in a dense, close, upright, terminal 

 panicle. A common, low shrub, but sometimes a tree twenty 

 feet high, with orange-colored, brittle wood. Often a great nui- 

 sance, appearing in neglected fields, and throwing up suckers 

 from the large, coarse, subterraneous stems. 



R. glabra, Linn. Smooth Sumach. Branches and leaves 

 smooth, not downy. Leaflets eleven to thirty-one, whitish un- 

 derneath, lanceolate-oblong, pointed and serrate. Fruit red, but 

 in an open and spreading cluster. A small or large shrub, some- 

 times ten or twelve feet high, and common in rocky soils. Var. 

 laciniata, or the Cut-leaved sumach of gardens, belongs to this 

 species, and was found in Pennsylvania by the late Dr. Dar- 

 lington, nearly a half century ago. 



R. opallina, Linn. Dwarf Sumach. Young stalks and 

 branches downy, petioles winged or broadly margined between 

 the nine to twenty-one, oblong or ovate-lanceolate leaflets, 

 mostly entire, smooth above and downy beneath. Fruit red. A 

 low shrub, four to eight feet high, on the borders of woods, in 

 both Northern and Southern States. 



R. aromatira, Ait. Fragrant Sumach. Leaves composed of 

 three cut-lobed leaflets, of a rhombic-ovate form, downy when 

 young, aromatic-scented. Flowers light yellow, and appear in 

 spring, before the leaves. Fruit red, in short spikes. Var. trilo- 

 bata, Gray, or R. trilobata, Nutt., is found from Texas to 

 Washington Territory. Fruit pleasant tasted, and eaten by the 

 Indians, The small, slender twigs, are also employed for 

 making very choice baskets. 



R. piimila, Michx Dwarf Sumach. A low growing shrub, 

 with eleven to thirteen oval, oblong, pointed leaflets, coarsely 

 serrate, and downy beneath. Fruit red and hairy. In Georgia 

 and North Carolina. 



R. integrifolia, Benth. and Hook. Entire-leaved Sumach. 

 Leaves evergreen, pubescent when young, but soon smooth ; 

 broadly ovate, usually entire, but sometimes spiny-toothed ; 

 one to three inches long. Flowers rose-colored, in close pani- 

 cles, one to three inches long. Fruit dark-red, viscid, ovate, 

 nearly a half inch long. Nuttall, in describing this species, 

 under the name of Styphonia integrifoUa, says that it is an un- 

 sightly tree, with a stem about the thickness of a man's arm, 

 branching in a wide and straggling manner, forming impervi- 

 ous thickets along the margins of cliffs and steep banks near
