Acropetal, a hybrid term, partly of Greek, partly of Latin derivation, in botany signifies developed in succession from base to apex. It is essentially identical with "centripetal," but is usually applied rather to elongated structures, as, for instance, the secondary rootlets originating from a tap-root or the leaves unfolding along a shoot. Structures which are not acropetal are termed adventitious.
