This opportunistic little Drosera is one of the most common carnivorous plant species in South Africa and can be found growing amongst fynbos during winter and spring.

Drosera trinervia is a perennial carnivorous plant and can be recognised by its small basal rosettes covered with reddish, sticky, glandular hairs. The palnts are only 50 - 100 mm high and have one or two long, slightly swollen roots. The wedge-shaped laminas (leaf blades) have slightly rounded ends, 10-20 mm long and 4-7 mm wide. The three veins on the underside of the lamina are most noticeable on dead leaves. Petioles (leaf stalks) are absent but stipules are present on either side of the base of the lamina margin. The stipules, in the form of two thin filaments, are inconspicuous and deciduous. The glandular hairs or tentacles are much larger at the top of the lamina than at the base. The lower surface of the lamina is smooth and without hairs (glabrous) or becomes smooth with age (glabrescent).

The flowering stalk originates directly from the centre of the plant. The inflorescence can reach up to 100 mm and 2-10 white or, infrequently, mauve to red flowers are borne closely together. The styles on the ovary are fringed at the top. Flowering occurs from August to November. Blackish-brown, ovoid seeds, 0.3 mm long, are formed in the oblong capsule.

This species is not threatened.

Drosera trinervia is endemic to South Africa and, as one of the most common species in the genus, has a wide distribution from Namaqualand in the Northern Cape to Agulhas in the Western Cape. Plants have also been recorded from KwaZulu-Natal and Lesotho. It occurs at altitudes from 15-2200 m.

Plant colonies are usually found in damp, peaty, exposed areas, on stream and river banks and in seeps or exposed flat or sloped areas amongst fynbos vegetation. This species is very opportunistic and will colonize any suitable habitat where there is sufficient moisture.
