R. glabra, var. laciniata. Cut-leaved Sumac. (D s) A beautiful low 

 variety of the preceding, with leaves of very large size, deeply cut, and droop- 

 ing gracefully from the branches. Autumnal color a rich red. 



R. semialata, var. Osbeckii. Osbeck's Chinese Sumac. (Sm) A fine 

 broad-headed tree, with deep glossy green foliage, of subtropical appearance, 

 which in autumn turns to shades of red and orange. The broad, terminal 

 panicles of creamy white flowers in July add much to its beauty. 



R. typhina. Staghorn Sumac. (S r) A densely hairy species, with ob- 

 long-lanceolate leaves ; flowers in dense, terminal panicles and fruit in red 

 clusters. Fall color of foliage is most brilliant. A good grower in light, dry 

 soils, and useful for planting on steep banks. 



ROBINIA. Locust 



Showy-foliaged trees, adapted to most soils, and thriving particularly well in 

 poor, dry situations. All with showy flowers, borne in dense, drooping panicles, 

 and very abundant. 



R. Pseudacacia. Black Locust. (Lr) An ornamental tree, with long, 

 oval leaves, producing racemes of fragrant white flowers in June. (See plate 

 on page 54.) 



R. Pseudacacia, var. foliis aureis. Golden-leaved Locust. (Mr) A 

 form of the above, with foliage of a rich golden yellow, which, combined with 

 its lace-like appearance, makes it one of the handsomest ornamental trees. 



SALISBURIA 



S. adiantifolia. Gingko, or Maidenhair Tree. (Mr) An ornamental 

 variety of vigorous growth, with clean, straight trunk and irregularly disposed 

 branches ; bark clean and pretty ; foliage leathery, closely resembling in shape 

 the Maidenhair Fern. 



SALIX. Willow 



One of the most valuable classes of ornamental trees and adapted to various 

 soils and situations. They are mostly rapid growers, with good foliage, their bright 

 bark giving distinct and pleasing winter effects. Indeed there are few trees of 

 which the varieties can be used to such good advantage for the winter color of their 

 bark. The Royal, Weeping, Golden Weeping, Laurel-leaved, Yellow and Salmon- 

 barked Willows, give all shades of greens and yellows, and the latter variety shades 

 off into deep, rich, bronzy red. 



S. alba, var. regalis. Royal Willow. (L r) A strong, sturdy and very 

 hardy variety. Its silver-gray foliage is rich and ornamental.
