The contrast of the red venation and the clear green blade on the leaves of a Macaranga tree results in an almost symmetrical pattern. A common park tree in Brisbane, Queensland.    //   Macaranga - Euphorbiaceae: Macaranga tanarius. About 24 similar-looking species in the genus. A small large-leafed (length to 40cm) tree growing to about 6m,  Macaranga is a component in the early succession of the re-establishment of tropical and sub-tropical rainforests.  It is one of the initial group of fast-growing species that quickly fill the void when a break occurs in the canopy of the forest and sunlight penetrates directly to the ground. Fast-growth = short life-span, and Macaranga quickly disappears as the longer-lived components of the mature rainforest return. In Australia M. tanarius occurs in sub-tropical and tropical lowland coastal rainforests from  New South Wales north through Queensland to the Northern Territory. Also in lowland rainforests of New Guinea, west through Indonesia to south-east Asia and Africa, and east to the south-west Pacific islands of Melanesia.
