How MULTIPLIED. Bulbs are renewed or multiplied annually at the ap- proach of winter by the development of bulbs from the axils of the scales, which increase at the expense of the old, and ulti- mately become detached. Bulbs which flow- er from the terminal bud are necessarily either annual or biennial: those flowering from an axillary bud may be perennial, as the termi- nal bud may in this case continue to develop new scales indefinitely. 193.
