"Dionaea ' Trichterfalle ' E.Koenig produces two types of leaves. In spring, late summer and autumn it mainly produces foliage that bears funnel shaped traps, that are up to 2.6 cm long and borne on erect foliage consisting of very elongated and narrow leaf bases that are up to 9 cm in length. The traps of these leaves are entirely fused at the proximal end of their lobes which results in their distinctive shape. The traps are positioned upright on elongated stalk-like petioles that are up to 1.8 cm long from the top of the leaf base.
During early summer, Dionaea ' Trichterfalle ' E.Koenig reverts to producing decumbent leaves that bear fully-formed traps that are up to 3.6 cm in length, although usually with abnormally long marginal lashes that are up to 1.4 cm long. The leaf bases of both the decumbent and erect leaves may bear variable ridges and wrinkles reminiscent of the scales-like structures of Dionaea ' Schuppenstiel I ' E.Koenig.
When exposed to direct sunlight, the traps of Dionaea ' Trichterfalle ' E.Koenig develop dark red interior surfaces and marginal lashes. A red line is present on the exterior of the traps, below the margins of the lobes. All other parts of the foliage are yellowish green. This cultivar can best be propagated through leaf and rhizome cuttings. Self-pollinated flowers yield seed, although only a minority of seedlings inherit the distinctive morphology."
