ON TREES AND SHRUBS. 5 I 7 



it' is useful for gardens of limited size, and is pleasing when 

 planted by the side of walks. T. b.f. argentea is similar in habit 

 to the last-named, but its leaves are striped with creamy-white, 

 which colour deepens with age. T. b.f. aurea, also of close habit, 

 has a portion of its leaves and growths marked with golden- 

 yellow. T. b. fructu-luteo is an attractive variety on account of its 

 fruit, which is yellow, whereas in the type it is red, thus affording 

 a welcome change. T. b. glauca differs from the type in the 

 under-sides of the leaves being of a glaucous hue ; it is a vigorous 

 form. T. b. nana is a dwarf variety, well adapted for the rock 

 garden ; it is of compact and rather spreading dense growth, 

 with glossy green leaves. T. b pyramidalis is a very ornamental 

 variety, differing from the type in being more compact and erect 

 in growth. T. b. Washingtoni is a beautiful variegated form, free 

 in growth, and its leaf-colouring is constant. T. cuspidata is 

 handsome, vigorous, and spreading, with deep green leaves. It 

 is serviceable for lawns. 



Thuya. — In the Thuya genus are how included Thuyopsis 

 dolabrata and Biota of gardens, and they form an important 

 section, suitable alike for small and large gardens. They are 

 natives of North America, China, and Japan, perfectly hardy, 

 easily accommodated, and differ much in habit, size, and leaf- 

 colour. 



T. dolabrata {Thuyopsis dolabrata) is a distinct Japanese tree, 

 admirably adapted for planting on lawns. It is of pyramidal, 

 bushy habit, and whilst young is of rather slow growth. The 

 flat, scale-like leaves are bright green above and glaucous beneath. 

 This species is well suited for small gardens, also for growing in 

 pots or tubs for placing in corridors, &c. . It delights in a moist, 

 well-drained soil and shady position beyond the influence of 

 cold winds. T. d. variegata is a pretty variegated form, distinct, 

 and of good growth. 



T. gigantea (T. Lobbi, T. Menziesii), introduced from North 

 America nearly fifty years ago, has been used extensively by the 

 landscape gardener. It is of rapid growth, and very ornamental, 

 with a trunk as straight as an arrow, furnished with numerous 

 short branches down to the ground. In proportion to its height 

 the branches are very short, giving it a compact, close habit, and 

 adapting it to gardens of limited extent. T. g. compacta is a 

 very handsome Conifer, and as its varietal name indicates, is of 

 compact growth. T. g. plicata (T. occidentalis plicatd) is similar 

 in habit to the type, but not so vigorous and more bushy. It is 

 of great decorative value, and thrives in poor soils and exposed 

 situations. T. g. p. lutea is of excellent habit, free in growth, and 

 by reason of the rich yellow tint of its foliage, is worthy of 

 recognition. It is very attractive in winter. 



T. japonica (T. Standishii, Thuyopsis Standishii), one of the 

 most ornamental of Thuyas, should be represented in gardens
