[[2][3]]They grow naturally only (endemic) in restricted habitat areas of central-eastern to south–eastern Queensland.[[2][9]]
Both the Australian national and Queensland state governments have given the official conservation status of "endangered" for this species' remaining populations of trees.[[11]]
Within their endemic region the trees grow naturally in habitats of seasonal–drought adapted rainforests and associated non-adapted to fire vegetation types, typically on nutrient–rich soils derived from basalt parent materials, which have historically had their native vegetation extensively destroyed and {{as of|2013|lc=y}} been further threatened.[[2][9]]
This species name and description was formally published for the first time in 1982 by Sally T. Reynolds of the Queensland Herbarium.[2][3]
