Acacia heterophylla Acacia heterophylla 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. It has been introduced into Madagascar where it grows in a subhumid climate at an altitude of about 500–1000 m above sea level. Genetic sequence analysis has shown its closest relative is "Acacia koa" of Hawaii; the estimated time of divergence is about
ʻApapane Lānai. Apapane generally feed on nectar from flowers, preferably from the "ōhia lehua" ("Metrosideros polymorpha") tree. These birds are mainly found in "koa" ("Acacia koa") and "ōhia lehua" forests where the flower count is high. Although primarily nectarivorous, the diet of a grown apapane also includes a variety of insects like grasshoppers, caterpillars and bugs of all sorts. The breeding season is from January through July. The nest of the apapane is usually placed in the crown of a "ōhia lehua" ("Metrosideros polymorpha"); nests have been found in tree cavities and lava tubes as well as in the top of
