The white potato forms at the end of slender underground branches elongated tubers upon which are numerous buds, any one of which, nourished by the reserve food in the tuber, may produce a new shoot.

The thick leaves of Bryophyl- lum are often blown off by storms, and prgduce new plants from buds formed at the teeth along the edge. Some species of Kleinia, natives of Cape Colony, have fleshy stems, jointed.
