species. The American Arbor Vite (TZ. occidentalis) is 
a small tree or large shrub of pyramidal growth and not 
wanting in attractiveness. It is, however, not equal for 
garden ornamentation to some of its numerous varieties. 
The best of the green-leaved forms are: T. o. El/wange- 
riana and T. o. Wareana, which are smaller in growth 
and of better colour than the type. T. o. /utea and T. o. 
Wareana aurea are the best of the golden-leaved forms. 
The Chinese Arbor Vite (TZ. orientalis) is of pyramidal 
outline, but the growth is hardly so erect as in the species 
immediately preceding it. T. 0. decussata and T. o. funi- 
culata are two beautiful green-leaved varieties, and 7. o. 
aurea and T. o. elegantissima are two effective golden 
forms, the former globular in growth, and the latter 
has a compact erect habit. 
WELLINGToNnIA.—The well-known Wellingtonia gigan- 
tea, which rises to a height of 350 feet in Sierra Nevada, 
where the conditions are very favourable, is an ex- 
cellent garden tree, although decidedly formal, where 
soil and climate are favourable to its development. It 
is of comparatively slow growth in Great Britain, and 
many years elapse before it becomes too large for a 
garden of moderate area. 
A deep loamy soil and shelter from easterly winds 
are essential to success, therefore where the soil is 
gravelly or a heavy clay, or the position exposed to 
easterly winds, the Wellingtonia should not be planted, 
because of the lower branches dying off at an early stage 
and spoiling the appearance of the trees.
