Sugar cane cuttings have been shipped long distances when treated with bordeaux and then packed in damp charcoal. 191. Leaf cuttings.âLeaves of cer- tain plants may be made to produce new plants. Some of these are planted whole, others cut in various ways. In certain cases (rex begonia) the new growth arises from adventitious buds, but in others (various ferns) it comes from true buds which originate in the stems. True buds may form on the leaves before being cut from the parent plant (Bryophyllum calycinum) or afterwards (rex begonia) ; normal in the former case, adventitious in the latter. Temperature and moisture condi- tions are the same for leaf cuttings as for soft wood cuttings. \\'hile many plants may be made to reproduce by leaf cut- tings (cabbage, lemon) few can be profitably so propagat- â ed. The process, in some cases, detroys variegation in the progeny; e. g., while certain variegated ivy geraniums may be reproduced by soft wood cuttings, they become plain green when leaf cuttings are used. In some cases whole lea^â es are used as cuttings, in others the leaves are cut in pieces. A whole leaf of be- gonia is placed flat on the propagating bench with a short .piece of its petiole buried in the sand. Cuts are then made across the main veins in various places and th
