Variety. 



* V. A. 2 latifolia Mill. (.V. Du Ham.,\\. 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.

V. icUrt Lam., Mill. Ic., t. 275. figs. 1. and 2. ; V. Negtinda Bot. Mag., t. 364. j 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.

 the greatest vigour, against the wall in the 

 Horticultural Society's Garden, where it 

 has stood since 1829 5 uninjured by any of 

 the winters that have occurred during that 

 period. 



Clcrodendntm spcciosissimum 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 2 in. in length, tubular below, 



1 I o3 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 

 " Pince have a very fine plant in the open border.

cydnea Hort. is a native of South America, and is general! 



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. \ J54, 



Aloysi'A, citriodora Or.; Ferbena triphylla//'//mY. ; Lfppirt citriodora Kunth, 

 Hot. 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 10ft., 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 Ferbena triphylla (Alojsia citriodora) is that of 

 which the luxuriance is in Guernsey the most remarkable. Its miserable 

 stinted growth, and bare woody stem, are well known to us. 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 clown 

 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, J4 ft. in length, resembling those of the osier willow, being annually 

 produced." (Quaykrt Jersey and Guernsey, Appendix, p. 341.) It is also com- 

 monly said that this shrub attains a large size in the Isle of Jersey j 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 steins as 

 us his wrist, and proportionably high.
