This is the case with many of our roses, dahlias, begonias, pelargoniums, orchids and other long or widely cultivated garden plants.
Gloxinias, begonias, &c., grow readily from fragments of the leaves cut clean through the thick veins and ribs, and planted edgewise like cuttings.
In delicate cases, such as seedling gloxinias and begonias, it is best to lift the little seedling on the end of a flattish pointed stick, often cleft at the apex, pressing this into the new soil where the plant is to be placed, and liberating it and closing the earth about it by the aid of a similar stick held in the other hand.
Amoena, amoena spectabilis, magnifica, paronychioides major aurea and amabilis; Alyssum maritimum variegatum; some of the dwarf varieties of Antirrhinum majus; Arundo Donax variegata; Begonias; Calceolarias; Cannas; Centaurea ragusina; Clematises, of which the hybrids of the Jackmanni type are best; Dahlia variabilis, and the single-flowered forms of D.
Pot and start tuberous-rooted begonias and gloxinias.
Among the orders more strongly represented in Sumatra than in Java are the Dipterocarpaceae, Chrysobalanaceae, sclerocarp 1Vlyrtaceae, Melastomaceae, Begonias, Nepenthes, Oxalidaceae, Myristicaceae, Ternstrbmiaceae, Connaraceae, Amyridaceae, Cyrtandraceae, Epacridaceae and Eriocaulaceae.
Tubers are also sometimes formed on aerial branches, as in some Aroids, Begonias, &c. The production of small green tubers on the haulm, in the axils of the leaves of the potato, is not very unfrequent, and affords an interesting proof of the true morphological nature of the underground shoots and tubers.
