"Dionaea ' Schuppenstiel I ' E.Koenig produces leaves that are up to 6 cm in length, bearing traps that are up to 4 cm long and 3.7 cm wide. The traps are usually slightly curved along the midrib. The adaxial surface of the leaf bases bear distinctive scale-like ridges and wrinkles. These structures are most noticable either side of the midrib. If grown exposed to direct sunlight, the interior surfaces of the traps suffuse pure reddish purple and a red line is often present on the exterior of the trap lobes, close to the lobe margins. The marginal lashes suffuse reddish purple, or are purple with white tips. All parts of the leaf bases, including the scale-like structures are yellowish green. In all other respects, Dionaea ' Schuppenstiel I ' E.Koenig is in line with wild type Dionaea Soland. ex Ellis.
Dionaea ' Schuppenstiel I ' E.Koenig is easy to propagate by rhizome or leaf cuttings." Bailey & McPherson, Dionaea:304 (2013)
