Some of the kinds thrive best when grafted on to a thin-stemmed Cereus. Treated in this way, R. sarmentacea makes 6 in. of growth in a season; whereas, on its own roots it would take about five years to grow as much. The following is a selection of the species cultivated in gardens. The genus Lepismium is now included in Rhipsalis.

This species resembles some of the angular-stemmed kinds of Cereus. It grows freely and flowers annually, if planted in a basket of fibrous soil, and suspended near the glass in a warm greenhouse or stove. It is attractive even when not in flower, owing to the form of its stems and the tufts of long, silky, white hair which spring from the notches. Syn. Lepismium myosurus. Mag. 2820.

It forms a straggling plant about 1 ft. high. Syn. Lepismium Knightii, Cereus Knightii. Mag. 3O78. A small, compact plant, with woody stems, densely covered with little fleshy, conical joints, resembling very closely the leaves of some of the Mesembryanthemums. They are green, with a few red dots, each bearing a very small tuft of the finest hair-like spines.

Flowers white, tinged with purple, springing singly from the notches, and composed of eight to twelve sepals and petals. Stamens and stigma erect, white, the latter four-rayed. This species is a native of Brazil, and was introduced in 1830; Flowering-season, October to December. It may be grown in a warm greenhouse, and treated as a basket-plant or as a small pot-shrub. Syn. Lepismium commune.
