Acacia xiphoclada Baker Mimosa heterophylla Lam.

[1] Acacia heterophylla, the highland tamarind,[2] is a tree (or shrub in its higher places) endemic to Réunion island where it is commonly named tamarin des hauts[1] 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.

It has been introduced into Madagascar[3] where it grows in a subhumid climate at an altitude of about 500–1000 m above sea level.

[3] Genetic sequence analysis has shown its closest relative is Acacia koa of Hawaii; the estimated time of divergence is about 1.4 million years ago.

[4][5] A. heterophylla sequences nest within those of the more diverse A. koa, making the latter species paraphyletic.
