ornamental variety of strong growth, with large foliage and very- 

 fine flowers. R. neo-mexicana is a tree of vigorous growth, and 

 useful for the park and garden ; it bears pale rose-coloured 

 flowers in short dense racemes in autumn. R. viscosa (R. glutinosa), 

 the Clammy Locust, is a beautiful park tree, bearing an abundance 

 of rose-pink flowers in short racemes during summer. It flowers 

 in quite a small state. R. Pseudacacia (Locust Tree) is a well- 

 known tree, and beautiful both in foliage and in flower ; a good 

 many varieties have been raised from it, and the following are 

 some of the best : Bessoniana forms a dense-headed tree, and 

 retains its rich green leaves until very late in the season ; it 

 is distinct, and free in growth, aurea is conspicuous on account 

 of its golden-coloured foliage ; this kind should always be planted 

 in a sunny spot. Decaisneana bears an abundance of pale pink 

 flowers ; fastigiata is of upright habit ; and semperflorens bears its 

 white flowers nearly the whole of the summer. Rehderi, angusti- 

 folia, and revoluta are also of interest. 



Rubus deliciosus, from the Rocky Mountains, is a graceful 

 and very showy Bramble of free growth, perfectly hardy, and 

 bears large pure white flowers with conspicuous golden-yellow 

 stamens. This is unquestionably the finest ornamental Bramble 

 grown, and deserves a rich, well-drained soil, and an open sunny 

 spot. R. odoratus produces large clusters of sweet-scented 

 purplish-red flowers from midsummer until autumn ; being a free 

 grower, it should be allowed plenty of head-room. The Nootka 

 Sound Bramble (R. nutkanus) was introduced from North 

 America by Douglas, in 1826; it bears white flowers in July 

 and August, and is at home when planted by the water-side. 

 R. roscefalius coronarius produces very freely delicately-tinted pink 

 rosette-like blossoms of great beauty when planted in a sheltered 

 nook. Another beautiful kind usually treated as a cool greenhouse 

 plant, but one that thrives out of doors in favoured localities, is 

 R. phcznicolasius (Japanese Bramble), a rapid-growing climber 

 with pale pink terminal racemes of flowers that are succeeded 

 by bunches of richly -coloured berries. R. biflorus, from the 

 Himalayas, is very conspicuous on account of its silvery-white 

 stems, which show up well in winter while the plants are leafless. 

 R. laciniatus, R. spectabilis, and R. crattcgifolius are distinct and 

 worthy of note. 



Salix (Willows). — For planting in damp ground, such as the 

 margins of lakes, streams, &c, the numerous species and varieties 

 of Salix are well adapted. They range from mere shrubs, ift. 

 high, to trees of 80ft. or so, and as the tall kinds are of quick 

 growth, they are suitable for landscape effect. The leaves are 

 mostly green and grey ; in winter the red, yellow, and green 

 stems are effective, and in spring are very pleasing with their 

 elegant catkins that are borne so freely. 5. babylonica, mentioned
