Biology:
South Australian material here referred to H. flaccida approaches the related H. collina in its generally smaller size and in the deep, narrow cup formed by the perianth-segments. Hybridisation occurs between these species (Goldblatt (1980) Bot. Notis. 133:85-95.), and the Australian populations, which are derived from horticultural stock and have been subjected to many generations of selection in a new ecological range, may lie on a hybrid continuum between the two species.
