Leaf gain and loss of A. myrtifolia were studied by Maconochie (1975). The plants studied were in the vicinity of the Para Wirra Reserve, Mt Lofty Ranges and remarkably produced no new growth in the first 12 months of study although they did flower. Thereafter shoot growth reached a peak in October following flowering. The peak of leaf loss more or less coincided with the peak of production.

For the results of seed chipping and hot water treatments on seed germination see Clemens et al. (1977).

The four taxa of native bees foraging on A. myrtifolia flowering in Victoria were studied by Bernhardt & Walker (1984). Most carried Acacia pollen and virtually all also carried pollen from other genera. Bees took secretions from the floral nectaries as well as collecting pollen.

Var. angustifolia Benth., Fl. Aust. 2:377 (1864)

This name has been applied to variants with distinctively long narrow phyllodes found on Kangaroo Island, see Fig. B. Well developed plants are readily recognised, but as some intermediates occur, more work needs to be done on the status of this variety which is largely confined to the lateritic uplands of the island.
