Pararchidendron

Pararchidendron pruinosum is an Australian rainforest tree growing from the Shoalhaven River (34° S) in New South Wales to Herberton (17° S) in north Queensland. It is also native to New Guinea and to Java, Sulawesi, and the Lesser Sunda Islands in Indonesia. Common names include Snow-wood, Tulip Siris and Monkey's Earrings. It is the sole species in genus Pararchidendron. The habitat of the Snow-wood is tropical, sub-tropical, warm temperate, littoral and riverine rainforest. Like most legume species, it fixes atmospheric nitrogen in the soil via its symbiotic partnership with root bacteria - trading the bacteria starches in exchange for nitrogen. It can be seen growing on sand within earshot of Seven Mile Beach, New South Wales....read more on Wikipedia.
