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
Lesser koa finch Lesser koa finch The lesser koa finch ("Rhodacanthis flaviceps") is an extinct species of Hawaiian honeycreeper. The only specimens of the lesser koa finch ever caught were a family group with members of different ages and genders, ideal for study. The males were apparently golden-yellow with olive green on the breast and belly. The females were almost indistinguishable from the species' larger relative, the greater koa finch, other than the fact that the former were slightly darker in color. The juveniles were somewhat mottled on the belly, similar to the females. As its name suggests, the species as a whole
