(Greek, sprouting leaf). Uranu Zdcew. A small genus of succulent plants in the same order with stonecrops, houseleeks and Cotyledon. The only species in cult. is a rapid-growing window-plant, and, like the Begonias, a familiar example of plants that are propagated by leaf-cuttings. It is hardly a decora tive plant, but is very odd and interesting. It is only necessary to lay the leaves on moist sand or moss, and at the indentations new plants will appear after a time (see Fig. 274). It is even possible to pin leaves on the wall, and without water new plants will come. Useful in botanical demonstrations.
