In the grassy open woodlands of the Stirling Range grows a pink flowered sundew in the D. macrantha complex. These plants appear most similar to D. indumenta based on its pink flowers and distally branched styles, which at least on the Swan Coastal Plain is sufficient to distinguish it from the white flowered D. macrantha. The current understanding of the species complex is that D. indumenta is separated on the basis of indumenta (hairs) that cover the entire length of the stem to the ground. Drosera macrantha has hairs only on the upper half of its stem. Critically, I did not take note of this feature in these plants so my identification can not be certain. These plants also inhabit a relatively drier niche in woodland flats, contrasting with the swampy habitats typical of D. indumenta.
