QUE-RCUS, continued 



Q. imbricaria. Laurel Oak. (Ls) A round-topped tree, somewhat 

 pyramidal when young. Branches slender and pendulous. The oblong, 

 laurel-like leaves are dark and glossy and the rich, reddish bronze autumn 

 foliage very handsome. A grand lawn tree. 



Q. macrocarpa. Mossy Cup Oak. (L r) A broad-headed tree, with 

 spreading branches and light brown, corky bark. The large, shining, bright 

 green leaves take a deep bronze fall color. The cup of the large acorn is very 

 deep and mossy. 



Q. palustris. Pin Oak. (L r) A round -topped tree, quite pyramidal in 

 its younger stages. Growth very upright ; branches long and somewhat pen- 

 dulous ; foliage dark green, deeply cut, and in the autumn turning to spark- 

 ling gold and crimson shades. Unsurpassed for fall color. Transplants 

 easily, grows well in wet or dry ground, and is one of the very finest trees for 

 lawn planting. (See plate on page 63.) 



Q. pedunculata, var. Concordia. Golden Oak. (Mm) A spreading, 

 broad-topped tree, with oblong, golden yellow foliage. 



Q. Phellos. Willow Oak. (Ms) Of rather conical form, with slender 

 branches and short, narrow, bright green leaves, which turn yellow in the fall. 

 A tree of willowy aspect, preferring a moist soil. 



Q. Prinus. Rock Chestnut Oak. (L r) A broad, irregular tree, with 

 deeply ridged brown bark. The long, light green leaves closely resemble 

 those of the American chestnut, and it takes for its fall color shades of scarlet, 

 bronze and golden yellow. A good grower in light, dry soils. 



Q. Robur. English Oak. (Mm) A round-headed, spreading tree, with 

 long, divided foliage of light green, which is retained very late. 



Q. Robur, var. fastigiata. Pyramidal English Oak. (Ss) A form of 

 very upright growth. Foliage smaller and less deeply cut than Q. robur. 

 A good tree for small places and formal plantings. 



Q. rubra. Red Oak. (Lr) A broad, symmetrical, spreading tree, with 

 stout branches. The dark green foliage is very rich, and turns to bronzy red 

 in the autumn. One of the best Oaks for lawn planting and unsurpassed for 

 street use. Transplants easily and is adapted to various soils. 



Q. velutina; syn., tinctoria. Black Oak. (Lr) A narrow, open- 

 headed tree, with rather slender branches and broad, dull green leaves, not 

 much divided. A good sort for dry soils and for street or lawn planting. 



RHUS. Sumac 



Trees with ornamental foliage, and in some instances showy flowers in dense 

 spikes, followed by ornamental fruits. These sorts are especially valuable for 

 grouping with other trees and shrubs for foliage effects, as the autumn colors are 

 brilliant. Adapted to a great variety of soils and situations. 



R. glabra. Smooth Sumac. (Sm) This forms a broad, low, open head. 

 The leaves are long and narrow ; flowers yellowish white, in terminal panicles; 

 fruit crimson. A desirable sort for specimen or mass planting.
