Drosera peltata occurs in moist coastal heathland in East Gippsland, on the Victorian side of the border with NSW. The plants here are mostly tall (>30cm) with well-spaced inflorescences held high above the last leaves. The sepal hairs are thick and lack glands at their tips. The seed is ovoid. The colour of the plants was orange-red at anthesis. Moderate branching occurred in large specimens, which is not unusual in seasons where the ground remains moist late into the year.

The plants here are specifically contrasted with D. gracilis, which is widespread in subalpine and lowland swamps and is distinguished by its gland-tipped sepal hairs and seed with a long, tapering appendage.
