498 ARBORETUM ET FRUTICETUM BRITANNICUM. 
4. H. H.1 vulgaris Dec. (Eng. Bot., t. 1267. ; 
and our jig. 908.) has the pedicels 
clothed with stellate down, and the fruit 
black. This is the commonest form of 
the ivy, throughout Europe, in a wild 
state; and there are varieties of it with 
white and yellow variegated leaves, in 
gardens. 
& H. H. 2 canariénsis Dec.; H. canariénsis 
Willd. Berol. Mag. ii. p.170. t. 5. f.1.; 
the Irish Ivy, or Giant Ivy, of British 
gardens; has the pedicels scaly with pu- 
‘bescence. Floral leaves subcordate ; 
those of the creeping branches 5-lobed 
and larger than those of the common 
ivy. Fruit ? red, or black. Canary 
Islands. Introduced in ? 1800, or before. 
i H. H. ?3 chrysocarpa Dec., H. poética 
C. Bauh., H. chrysocarpos Dalech., H. Dionysias J. Bauh., H. 
Halix Wall., is a native of the North of India, with yellow fruit. 
It differs from the common ivy in its yellow fruit, and in being of 
more gigantic growth; in the leaves being more cuneated at the 
base; and in the pedicels being scaly. Hort. Society’s Garden. 
908. H. H. vulgaris. 
The Varieties in British Gardens, additional to the above, are: — 
a H. H. 4 foliis argénteis Lodd. Cat. The Silver-striped Ivy. 
& H. H. 5 foliis awreis Lodd. Cat. The Golden-striped Ivy. 
& H. Hz. 6 digitata Lodd. Cat. The palmate, or Hand-shaped, Ivy. 
& H. H. 7 arboréscens Lodd. Cat. he arborescent, or Tree, Ivy.— This 
variation is merely an extension of the flowering shoots, which are 
entire-leaved, and take an arborescent character; and, when a portion 
of them is cut off, and has rooted as a separate plant, it will sometimes 
produce an upright bush, which will retain its arborescent form for 
many years. Sooner or later, however, it resumes its native habit, 
and throws out rambling, or creeping, shoots, with 5-lobed leaves 
like the common ivy. 
A variety with white berries is mentioned by Theophrastus, Pliny, Virgil, 
and Dioscorides. 
The ivy will grow in any soil or situation, but thrives best when somewhat 
shaded. The common British variety, and its sub-varieties, are the best 
kinds for supporting themselves on walls, especially when young; at which 
period the giant ivy seldom throws out rootlets, though it does so subsequently.
