*Yucca flaccida.—A stemless species, somewhat resembling Y. filamentosa, but smaller, with a downy branching panicle 3 ft. to 4 ft. high. Foliage in close rosettes of leaves, 1½ ft. to 2 ft. long, by about 1½ in. broad at the middle, often fringed with filaments on the edges: the young ones nearly erect, the old ones abruptly reflexed at the middle, almost appearing as if broken. This gives such an irregular aspect to the tufts that it at once distinguishes this kind from any of the varieties of Y. filamentosa. It also flowers more regularly and abundantly than its relative, and is exceedingly well suited for groups of the finer hardy plants, for borders, or for being planted in large isolated tufts. N. America.
*Yucca glaucescens.—A very free-flowering kind, with a panicle 3 ft. to 4 ft. high, the branches of which are short and very downy. Leaves sea-green, about eighteen inches long, with a few filaments on the margins. The flowers are of a greenish-yellow colour, and when in bud are tinged with pink, which tends to give the whole inflorescence a peculiarly pleasing tone. A very useful and ornamental sort—fine for groups, borders, isolation, or placing among low shrubs. N. America.
*Yucca gloriosa.—A species of large and imposing proportions, with a distinct habit and somewhat rigid aspect. Flower-stem over 7 ft high, much-branched, and bearing an immense pyramidal panicle, of large, almost pure white flowers. Leaves numerous, stiff, and pointed. One of the noblest plants in our gardens, and suitable for use in almost any position. It varies very much when grown from seed—a good recommendation, as the greater variety of fine form we have the better. The chief varieties in cultivation are Y. g. longifolia, plicata, maculata, glaucescens, and minor. The soil for this plant should be a rich deep loam. N. America.
*Yucca pendula.—The best species perhaps, considering its graceful and noble habit, which is simply invaluable in every garden. It grows about 6½ ft. high, the leaves being at first erect and of a sea-green colour, afterwards becoming reflexed and changing to a deep green. Old and well-established plants of it standing alone on the grass are pictures of grace and symmetry, from the lower leaves which sweep the ground to the central ones that point up as straight as a needle. It is amusing to think of people putting tender plants in the open air, and running with sheets to protect them from the cold and rain of early summer and autumn, while perhaps not a good specimen of this fine thing is to be seen in the place. There is no plant more suited for planting between and associating with flower-beds. N. America.
*Yucca rupicola.—A species somewhat resembling Y. aloïfolia, with a stem from 4 ft. to 7 ft. high, and pale-green leaves 18 ins. to 20 ins. long, by 1 in. broad at the middle, almost erect and frequently twisted, the horny margin being broader and the teeth more distinct than in Y. aloïfolia. This is not much in cultivation as yet, and will probably be difficult to obtain for some time to come. N. America.
*Yucca Treculeana.—This species is one of the most remarkable of the noble genus to which it belongs, from its habit, and especially from the dimensions to which its foliage attains. Like many plants of its family,
