Arisarum is a genus of flowering plants in the family Araceae. It is native to the Mediterranean region, east to the Caucasus and west to Macaronesia.[2][3][4]
Taxonomy[edit]
Species[edit]
Accepted species:[2]
Image | Scientific name | Distribution |
---|---|---|
Arisarum simorrhinum Durieu | Portugal Spain, Balearic Islands, Algeria, Morocco | |
Arisarum proboscideum (L.) Savi | Spain, Italy | |
Arisarum vulgare O.Targ.Tozz. | Mediterranean region of northern Africa and southern Europe from Portugal and Morocco to Turkey and Israel; Caucasus; Canary Islands, Madeira, Azores |
Natural Hybrids[edit]
- Arisarum × aspergillum Dunal - Spain, Algeria, Morocco (A. simorrhinum × A. vulgare)
Phylogeny[edit]
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]
Description[edit]
In A. 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]
Ecology[edit]
Parasite ecology[edit]
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]
