Drosera macrantha is a native sundew species. It is particularly common in dry heathlands and open forests of north-eastern Tasmania and the Furneaux Group. Superficially it resembles D. peltata in having peltate leaves (i.e. attached in the middle of the lamina) and erect leafy stems, but the leaves are circular and occur in clusters of three, and it is more of a scrambling plant.
