Drosera stolonifera

A species with mostly 2-3 semi-erect stems reaching up to 15 cm in length. The stems arise from a basal rosette always located on the substrate surface (in contrast to D. porrecta). The inflorescence also arises from the basal rosette and in some cases additionally from the leaf axil along the upper parts or the apex of the semi-erect stems. The tuber is red.

The stolon arises from the tuber vertically, but then bends horizontally prior to breaking through the substrate surface (see pictures below). This habit is shared with D. purpurascens and to some extent with D. humilis. D. stolonifera differs from D. purpurascens in size, additional leaves produced from the basal rosette (present in D. purpurascens, absent in D. stolonifera) and the observation that non-flowering specimens are often branched in D. stolonifera whereas non-flowering D. purpurascens often produce only one leafy stem.
