There is a single record of Lysiana exocarpi and many more, but almost equal, numbers of Amyema preissii, wire-leaved mistletoe and Amyema pendulum, drooping mistletoe, more often found on Eucalyptus. Phyllodes were produced more rapidly on populations from drier sites, and the relative size of the bipinnate leaf was related to the site rainfall.The cell structure and morphology of the phyllode of A. melanoxylon was studied by Boke (1940). In cultivation, A. melanoxylon needs to be managed properly to ensure that it does not become invasive. Synonyms.

Acacia heterophylla, the highland tamarind, is a tree (or shrub in its higher places) endemic to Réunion island where it is commonly named tamarin des hauts The tree has a juvenile stage where its leaves have a pinnate arrangement, but in the adult stage the leaves diminish and the phyllode becomes the dominant photosynthetic structure.. The onset of phyllode development after the juvenile phase ranged from 2 months to 7 months. Then rachis develops into leaf like phyllode. Upon exposure to low temperatures, mesophyll cells in the phyllode of Acacia melanoxylon shrank and the intercellular spaces increased with decreasing temperature, due to apparent freezing of the bulliform cells (Ruan et al., 2011).
