A small, deciduous terrestrial orchid from Queensland's tablelands that grows from an underground tuber and bears a few tiny dark flowers in late season. It is a wild native rather than a common garden plant, so growing it means matching its open, seasonally dry forest habitat.

About
Genoplesium alticola, commonly known as tableland midge orchid, is a small terrestrial orchid endemic to Queensland, Australia. It has a single thin leaf fused to the flowering stem and up to twenty five small, hairy, dark purplish-red and green flowers. It grows in two small areas of the state at altitudes between 600 and 750 m (2,000 and 2,500 ft).
Where it grows
At the time it was first described in 1991, this species was known from only two locations — the Herberton Range west and south of Atherton and on Walshs Pyramid approximately 45 km (28 mi) to the east of Atherton. As of October 2025 there are nine occurrences recorded, ranging from Mount Windsor, west of Cape Tribulation, south to about Cardwell. It has been found in open stunted forest on ridges, on clay and sandy soils, at altitudes around 600 to 750 m (1,970 to 2,460 ft). It often grows amongst low shrubs, herbs and grasses.
