Derivation. The name of the plant in Peru .

Description, S>c. Low evergreen shrubs, with the habit of palm trees;natives of North and "South America. In British gardens, most of the speciesare somewhat tender. They prefer a dry and deep sandy soil, or a sandyloam ; and they are readily propagated by suckers, which are thrown up bythe roots, or by side shoots, which are occasionally produced on the stem.They sometimes ripen seeds, which, if sown immediately after they aregathered, and placed on a moderate hot-bed, will come up in six weeks. Intheir native countries, their leaves, treated like the stalks of hemp or flax,afford a fibre which may be used like that of those plants, in the manufactureof cloth or cordage; and the stems, macerated in water, deposit a feculentmatter, from which starch may be procured. In a floricultural point of view,all the species are highly ornamental; and no lawn or flower border ought tobe without some of them. Considered with reference to landscape-gardening,the yucca, like other trees and shrubs of formal shapes and rigid habit, whenplanted in masses, cannot readily be made to harmonise with the masses sur-rounding it; but, as a single object, it is well adapted for attracting attentionon a lawn, for the summit of a formal knoll, for growing out of rockwork,for ruins, and for various purposes of a similar nature. As the yucca growsnaturally on the sea shore, it is particularly adapted for marine gardens. Inimitating Italian scenery round an Italian villa, the yucca, planted in largevases, may be substituted for the agave. Plants, in the London nurseries,are from 2 s. to 5s. each.

* Y. g. 2 folds variegatis Lodd. Cat. , ed. 1836, has the leaves variegated.

Description, $c. This species has a stem, or trunk, about 2 ft. or 3 ft. high,clothed with leaves almost to the ground. The leaves are broad and stiff, butthin : they are of a very dark green, and end in a sharp black spine. The flower-stalk is generally about 3 ft. high, branching out on every side to a considerabledistance; but the flowers are very wide asunder on the stalk. Sometimes thepanicles of flowers spring at once from the centre of the leaves, without the in-tervention of a stalk. The flowers are bell-shaped, and hang downwards; andeach petal is white within, but is marked with a purple stripe on the outside.They are scentless,appear from July to September, but are seldom succeeded byseeds in England. This yucca is a native of Virginia and Carolina, of Cartha-gena in New Spain, and of the West Indies ; and, though a native of warm conn-
