NOTE: indeterminate growth in a plant is one in which the axis of the plant is not limited by development of a terminal flower bud or other reproductive structure and so continues to elongate indefinitely, as in racemose inflorescence (WIII); in indeterminate inforescences like racemes, the oldest flowers are borne towards the base and new flowers are produced as the shoot grows, with no predetermined growth limit (Wikipedia): crescentia,-ae (s.f.I) indeterminata; inflorescentia,-ae (s.f.I) indeterminata; cf. determinate growth;

- semper incrementum indeterminatum ostendenti, always showing indeterminate growth.
