A number of theupright-growing species of Cereus have been used successfully forstocks, and there seems to be no limit to the number of speciesthat may be used. It has been found, however, that some arebetter than others for the purpose. When it is desired to havethe scion a foot or more high, good stocks may be obtained fromCereus stellatus, C. serpentinus, and other species of similar habitsof growth. These stocks are preferable for use in grafting CereusfiagdUformis and species of Epiphyllum and Rhipsalis, which nor-mally grow in a pendent position. Where only short stocks aredesired the above may be used, and also Cereus nycticalus, C. tor-tuosus, C. bomplandii, C. macdonaldiae, and C. grandiflorus. Theselatter plants are weak stemmed when allowed to grow tall; hence,they can not be used for high grafts unless supporte
