The Drosera montana A.Saint-Hilaire complex is reviewed, discussed and three taxa are excluded from this group: Drosera hirtella A.Saint-Hilaire, D. parvifolia A.Saint-Hilaire, and D. roraimae (Klotzsch ex Diels) Maguire & Laudon. Morphological characteristics, distribution, and habitat preferences, are described for the rare Drosera montana A.Saint-Hilaire var. schwackei Diels. Based on the differences observed between this taxon and other Drosera species native to South America, it is here proposed that it should be elevated to specific status and the new combination D. schwackei (Diels) F.Rivadavia is made.
