Syzygium hemilamprum
Introduction '''''Syzygium hemilamprum''''', commonly known as the '''broad-leaved lilly pilly''', '''blush satinash''', '''cassowary gum''', '''Eungella gum''', and treated as ''Acmena hemilampra'' in New South Wales and Queensland, is a species of flowering plant in the family Myrtaceae and is native to New South Wales, Queensland and the Northern Territory. It is a rainforest tree with broadly lance-shaped to elliptic leaves, panicles of white flowers and more or less spherical white fruit.
Description ''Syzygium hemilamprum'' is a tree that typically grows to a height of  with a diameter at breast height of up to . The trunk is flanged or buttressed in larger trees, and has fissured and flaky reddish-brown bark. The leaves are arranged in opposite pairs, broadly lance-shaped to elliptic,  long and  wide on a petiole  long. The leaves are glossy and more or less glabrous on the upper surface and paler below. The flowers are arranged in panicles on the ends of branchlets, each flower on a pedicel  long. The sepals are joined at the base forming a tube about  in diameter, the sepal lobes small and inconspicuous. The petals are more or less circular,  long and the stamens  long. Flowering occurs from October to November and the fruit is white and more less spherical,  in diameter.
Taxonomy This lilly pilly was first formally described in 1875 by Ferdinand von Mueller and given the name ''Eugenia hemilampra'' in ''Flora Australiensis''. In the same publication, von Mueller also gave it the alternative name ''Eugenia smithii'' var. ''hemilampra'' and both names are validly published. In 1938, Elmer Drew Merrill and Lily May Perry changed the name ''E. hemilampra'' to ''Acmena hemilampra'' in the ''Journal of the Arnold Arboretum'', and the name ''Acmena hemilampra'' Merr. & L.M.Perry is the name used by the National Herbarium of New South Wales. Then in 2006, Lyndley Craven and Edward Sturt Biffin changed von Mueller's ''E. hemilampra'' to ''Syzygium hemilamprum'' in the journal ''Blumea''. The name ''Syzygium hemilamprum'' is accepted by the Australian Plant Census.
Distribution and habitat Often seen on sand by the sea in littoral rainforests, it reaches its best development in the red/brown volcanic soils, such as around the Mount Warning caldera. The natural range of distribution is from Yamba to Cape York Peninsula in the far north eastern tip of Australia. Removal of the flesh from the seed is advised to assist seed germination. Germination is slow, taking up to 80 days. However, cuttings strike well.
