Distribution and Ecology

Endemic to NEQ where it is known from three localities on the Bellenden Ker Range and headwaters on the Russell River. Altitudinal range from 590 to 1560 m, though records occur above 1460 m. Mainly grows in microphyll-notophyll vine fern thickets on granite substrate, but in the Russell River grows in complex notophyll rainforest on soil derived from mudstones.
