Distribution and Ecology

Endemic to Queensland, occurs in CYPNEQ, CEQ and southwards as far as southern inland Queensland. Altitudinal range from sea level to 900 m. Grows in open forest and brigalow scrub but appears to attain its best development in monsoon forest at least in the northern part of its range.
