Drosera basifolia is an erect tuberous sundew named after its densely clustered leaves at the base of the stem.

Drosera basifolia has a glabrous self-supporting that grows around 20cm tall. The base of the stem has densely clustered leaves that are characteristic of the species. These leaves have a petiole that is pressed upwards against the stem and turn to face the laminae outwards. The leaves on the upper portions of the stems are sparsely placed. The sepals are densely covered with short, glandular hairs. The flowers are pink and up to 3cm in diameter.

The species grows in clayey substrates on creek lines. It is distributed in the hills north east of Perth around Wongan to the Wheatbelt near Quairading.

Drosera basifolia is closely related to the other members of the D. menziesii complex. It is distinguished by its closely clustered basal leaves absent in the other species. It is most similar to Drosera menziesii in size and stature (D. thysanosepala and D. drummondii are long and scrambling). Drosera menziesii does not have closely packed leaves at the base of the stem.
