Like other members of its section, the habit of the taxon widely differs between the flowering and non-flowering forms that the plant takes in its life cycle.

Like other Drosera, the leaves of this taxon are reddish and circular, covered in carnivorous glands that allow it to capture and digest various types of arthropods.

Unlike some members of the genus, the circular leaves of D. monticola are incapable of folding onto any prey that they catch.

While its discoverers have stated that the taxon can probably be found on the summits of other mountains within the Stirling Range, actual specimens have only been collected from the two peaks previously mentioned.

In a 2005 journal article, Lowrie elevated the subspecies to the species level as Drosera monticola but did not properly cite the basionym of the proposed species, making the new scientific name invalid according to Article 33.4 of the International Code of Botanical Nomenclature.
