Dionaea ‘Cross Teeth ‘ produces leaves up to 6cm long, bearing traps that are up to 3.1cm in length. The leaves consist of narrow and succulent leaf bases and elongated petioles. The lobes of the traps are almost orbicular and their margins are often folded inwards, giving the traps a boxy appearance. Up to four marginal lashes can be fused together at their bases, forming triangular blades.
In summer, the foliage of this cultivar can be extremely colourful. The inner surfaces of the trap lobes, the margins of the traps and the marginal lashes may suffuse dark red or pinkish while all other parts of the foliage are yellowish green.
