It is closely related to the genera Ambrosina, Peltandra, and Typhonodorum. Ambrosina is the sister group to Arisarum, from which it separated about 46.1 Million years ago.[1]
The precise relationships are displayed in the following cladogram:[1]

InA. simorrhinum, the flower stalk is shorter or equal in length to the leaf stalk, whereas in A. vulgare, the flower stalk is longer than the leaf stalk. A. vulgare also has a generally longer spadix than A. simorrhinum.[5]
Arisarum foliage is parasitized by the siphonous green algae Phyllosiphon arisari Kühn. It induces necrosis in leaf tissue, after invading the intracellular space.[6] The foliage also may be affected by two species of fungi, namely Phyllosticta arisari and Melanustilospora arisari. The scale insect Icerya purchasi also feeds on Arisarum.[7]
