Drosera menziesii is an erect species widespread in the south west of Western Australia. The species has a glabrous stem and orbicular laminae that are typically coloured vivid red. Its sepals are covered with a dense layer of glandular hairs and the flowers are pink. It is associated with wet niches such as the edge of swamps and on soils atop shallow granite outcrops.
It is the type species of the Drosera menziesii complex, which includes D. thysanosepala, drummondii and basifolia. Drosera menziesii sensu stricto is identifiable firstly by its erect and self supporting stems, in contrast with the long scrambling stems of D. thysanosepala and D. drummondii. Its leaves emerge from the central stem at relatively regular intervals (D. basifolia has very dense leaves at the bottom portion of the stem).
