ON TREES AND SHRUBS. 



leaves of which are pale yellow. T. or. compada vs, a distinct^ and 

 pleasing variety of dwarf habit, and its bright green leaves give 

 it a cheerful appearance even in the depth of winter. T. or. 

 'elega7itissiina is another beautiful variety, of erect, compact habit, 

 with yellow foliage. This variety originated in a bed of seedlings 

 at the Tooting nursery of the once famous nurserymen, Messrs. 

 Rollinson. T. or. ericoides {^Retinospora ericoides) is a gem 

 amongst rock-garden Conifers, as it presents an attractive 

 appearance at all seasons of the year ; in spring the leaves are 

 tender green, and towards autumn they change to a brownish- 

 violet shade. It forms a conical shrub rarely exceeding 3ft. 

 high, and the short branchlets are crowded with narrow leaves, 

 glaucous on the under-sides ; an excellent sort for winter 

 bedding. T. or. falcata varies in height from 8ft. to T2ft., is 

 quite distinct, and deserving of extended culture. T. or. gracilis 

 is noteworthy on account of its slender, elegant growths, com- 

 pact habit, and free growth. T. or. meidensis l^Retinospora mel- 

 densis)^ a supposed hybrid between the Virginian Red Cedar and 

 the Chinese Arbor Vitse, is of loose, pyramidal habit, the slender 

 branches being clothed with short glaucous green leaves, which 

 in autumn assume a brownish-red, and retain that colour until 

 spring. It is not, however, sufficiently ornamental to be recom- 

 mended for general planting. T. or. fninima deserves a place 

 in the rock garden. It forms a dense, low bush, and its bronzy 

 foliage is attractive in winter. T. or. semperaurescens^ of French 

 origin, is unquestionably the most distinct golden-leaved Thuya, 

 and one of the most useful of its class for the garden, forming 

 a neat, globular bush. It is well adapted for winter-bedding, 

 and useful for window-boxes, as well as for pot culture for 

 winter decoration. 



TsuGAS (Hemlock Firs). — These form a small group of about 

 six species of Conifers, of much value for decorative planting. 

 North America is the headquarters of the family, and they are 

 all of elegant growth, hardy, and delight in moist soil and an 

 open situation, but the position must be sheltered from east 

 winds. They are splendid lawn trees, and should be more 

 frequently planted. 



T. Briinoniana {Abies Brunoniana, A. diwtosd), from the 

 central portion of the Himalayas, cannot, unfortunately, be 

 recommended for general culture in the British Isles, but in the 

 South of England it makes a really handsome specimen. It 

 forms a dense bush or small tree, with elegant drooping branches, 

 and when bearing its small-pointed, glaucous-coloured cones, 

 is an object of great beauty. T. canadensis {Abies canadensis), 

 a well-known member of the family, is a beautiful decorative 

 tree, thoroughly hardy, and of excellent habit. Its slender 

 branches and drooping branchlets are clothed with light green 

 leaves, glaucous on the under-sides. The attractive cones are
