This plant was found in the range above Ormiston Gorge in the Western MacDonnell during the month of April (after considerable rainfall). The flower appears above the leaves on a stem about 2-3 cm high.

They are listed as near threatened species in some areas of its range, such as Ruby Gap Nature Park.
