Abstract Subtype PIII sieve-element plastids, anthocyanins, spinulose, perforate-tectate pollen grains and the specific seed-coat sculpturing found in twoMacarthuria species (M. australis, M. neocambrica) consolidate their placement withinMolluginaceae. The unique form of the sieve-element plastids, i.e. with cubic crystals and starch grains (PIIIc″fs), finds its closest counter-part inLimeum. The multiple intertwinement of different genera of theMolluginaceae with many other centrospermous families led to a consideration of their more central position withinCaryophyllales.
