It forms a few rhizoids at the base of the inflorescence shafts .
Stolons and traps
The numerous, up to 10 millimeters long and 0.1 to 0.15 millimeters thick, branched stolons are provided with numerous egg-shaped, approximately 0.25 mm long, stalked traps that carry a single, bent back, awl-shaped appendage at their opening another, split, curved forward at its tip.
leaf
Stalked leaves grow from the stolons and also carry traps. The dark green leaf blade is very narrowly linear with a length of up to 8 millimeters and a width of 0.1 to 0.25 millimeters. The stipules are egg to delta-shaped with a length of up to 1.5 millimeters, taper to a point and are strongly toothed.
