Circæa (Enchanter’s Nightshade). Onagrarieæ.

Seeds; also by the running roots.

Cissampelos. Menispermaceæ.

Propagated by cuttings, which root readily in heat.

Cissus. Ampelideæ.

Propagated by cuttings in the spring. Choose the weakly shoots that are pruned just before the plants break into new growth, or allow the young shoots to grow to a length of about two inches. Then cut them off, with a small piece of the base branch adhering to the young wood; or the shoots may be cut off with one or several of these young branchlets on them. Cut the old branch through at the base of each young one, and insert the cutting with this heel of the old wood entire. In this country, usually grown from common green cuttings in summer.

Cistus (Rock-Rose). Cistineæ.

Propagated by seeds, by layers or cuttings under frames outside, or inside with a gentle bottom heat; but seedlings always make the best plants. The seeds should be sown early in the spring in pans or boxes in a frame, and lightly covered with sifted sandy mould. Cuttings should be made from three to four inches long. They may be struck in spring or autumn, in sandy peat under glass.

Citron (Citrus medica). Rutaceæ.

Seeds, which usually reproduce the kind. Mature cuttings, the same as lemon. Also budded on orange, lemon or lime stocks.
