1286 ARBORETUM AND FRUTICETUM. PART III. 
Variety. 
2% V, A. 2 latifolia Mill. (N. Du Ham.,vi. p.116.) has the leaflets broader 
and shorter than those of: the species. The spikes of flowers 
are shorter, and the flowers are always blue. It is a native of the 
south of France and Italy, and was known to Lobel and Bauhin. 
There are plants of it in the Cambridge Botanic Garden. 
App.i. Half hardy Species of Vitex. 
V. inclsa Lam., Mill. Ic., t. 275. figs. 1. and 2.; V. Negdéndo Bot. Mag., t. 364.; is a native of 
China, where it grows to the height of 4 ft., and flowers from July to September. It was introduced 
in 1758, but is not common in green-houses. 
App. 1. Half-hardy Plants of the Order Verbendcee. 
Clerodéndrum inérme R. Br.; Volkameéria 
inérmis Z., Jacg. Suppl., 117. 4. f. 1.5 
and our fig. 1153, This shrub grows, with 
the greatest vigour, against the wall in the 
Horticultural Society’s Garden, where it 
has stood since 1829; uninjured by any of 
the winters that have occurred during that 
period. 
Clerodéndrum speciosissimum Paxton’s 
Mag. of Bot., 3. p. 217, A branching shrub, 
growing to the height of 4 ft., with an erect 
stem, and cordate pointed leaves, and flowers 
produced in large spreading terminal pani- 
cles, of a vivid scarlet colour, and each 
> averaging Zin. in length, tubular below, 
1153 with a 5-parted spreading limb. The native 
country of this plant is not stated ; but it is probably Japan. Messrs. Lucomb 
and Pince of the Exeter Nursery received the plant from Belgium in 1835, 
and it flowered profusely in their nursery in August and September, 1836, 
and at Chatsworth in October of the same year. Mr. Paxton describes it as 
one of the finest plants which he has had the good fortune to figure; and as 
far superior in beauty to any of the family to which it belongs. Messrs. Lucomb 
and Pince have a very fine plant in the open border. 
Durdnta cyanea Hort. is a native of South America, and is generally 
considered as a hot-house plant; but a plant has stood against the wall 
in the Horticultural Society’s Garden since 1833; and, though the shoots 
are killed back during the winter season, it always grows vigorously during 
summer, attaining nearly the height of the wall. 1154 
Aloysia citriodéra Or.; Verbéna triphylla L’ Hérit.; Lippia citriodora Kunth, 
Bot. Mag., t. 367.; and our fig. 1154.; is a native of Chili, and has been in 
the country since 1784. In dry soils, in the neighbourhood of London, it 
will live in the open border for many years, without any protection, except 
a little litter thrown about the roots; for, though frequently killed down to 
the ground, it seldom fails to spring up with vigour the following spring, 
and continue flowering the greater part of the summer. In the Chelsea Bo- 
tanic Garden, there is a plant against the wall, which in six years has attained 
the height of 10 ft., growing vigorously, and flowering freely. The leaves are 
gratefully fragrant when slightly bruised ; and on this account, and also on that 
of its small elegant whitish flowers, it well deserves a place in collections. Of 
all those shrubs, Dr. Macculloch observes, “ which require the protection of a 
green-house in England, the Verbéna triph¥lla (Aloysia citrioddra) is that of 
which the luxuriance is in Guernsey the most remarkable. Its miserable 
stinted growth, and bare woody stem, are well known tous. In Guernsey it 
thrives in exposed situations, and becomes a tree of 12 ft. or 18 ft. in height, 
spreading in a circle of equal diameter, and its long branches reaching down 
to the»ground on all sides. Its growth is indeed so luxuriant, that it is 
necessary to keep it from becoming troublesome by perpetual cutting: fresh 
shoots, 14 ft. in length, resembling those of the osier willow, being annually 
produced.” (Quayle’s Jersey and Guernsey, Appendix, p. 341.) It is also com- 
monly said that this shrub attains a large size in the Isle of Jersey; but a 
writer in the Gardener’s Magazine, vol. xii. p. 551., says that he expected to 
see it generally cultivated, but that the only plant he saw in the island was 
one in the garden of a nurseryman, and that not of extraordinary size. The 
nurseryman, however, told him there were trees in the island with stems as 
thick as his wrist, and proportionably high.
