Synonyms are C. esculenta var. globulifera Eng,I. and Krause; C. antiquorum var. esculenta Schott; C. antiquorum Schott. The Eddoe is currently considered to be C. esculenta var. antiquorum and the Dasheen C. esculenta var. esculenta. The taxonomy of the cultivars of Co/ocasia remains subject to further investigation.
Common names are Elephant Foot Yam, Giantarum, Sweet Yam (Eng.); Suran, Arsaghna, Balukund, Kidaran, Telinga Potato, Zaminkund (Ind.); Chena, Karak-kavanai (Mal.); IlisIlls, Kand Godda, Sooweg, Waloor (Indon.); Anto, Oroy, Pangapong, Tigi (Philipp.); Koe (Polyn.); Konjac, Konniaku (Jap.); Mo-yu (Chin.)
Cultivars are in selected regions of the local area.
Areas of cultivation includes Malaysia, Indonesia, Sri Lanka, the Philippines and Pacific area. Some authorities consider that two forms of the species exist: a wild form, var. sylvestris, with rough petioles; and the smooth petiole form, var. hortensis. In Indonesia, the closely related species A. oncophyllus Prain and A. varialbis Bl. are cultivated. Amorphophallus rivieri Durieu var. konjac Engler, is known as Elephant Yam in Japan and tropical areas of China where it is cultivated.
Areas of cultivation is throughout Polynesia, including Papua New Guinea and the Philippines. C. senegalense Engl. is a related species, the leaves of which are used in West Africa in the preparation of sauces.
An erect herbaceous perennial, up to 2 m in height. The West Indian or Trinidad Dasheen normally has a large main corm or tuber with a few side tubers; the Eddoe has a relatively small main corm but produces many small, oval cormels or tubers from the base of the stem which mature earlier than those of the Dasheen; the size of corms or tubers varies according to environmental conditions. Leaves: pale green or purple, ovate, peltate, with long petioles from 30-90 cm in length; surface covered with a fine, white deposit.
Small corms or portions of 3-year old corms are planted on flat beds or ridges at a depth of 10-15 cm at a spacing of 30-100 cm X 30-60 cm, depending on the age and size of the corms. An estimated 1680-2000 kg/ha of corms may be required for large-scale plantings. Mulching or shading may be required in the early stages of growth, weeds should be controlled and earthing up may be necessary as the crop matures. The corms are usually dug up and replanted over a 3-year cycle.
The crop matures in 220-350 days from planting and the corms are excavated when the leaves become senescent. The corms have a dormancy period of 60-90 days. After 3 years of growth, the corms weigh 7-9 kg each and are considered marketable. Yields of 20 t/ha have been reported from India.
The corms are carefully cleaned and stored in heaps, preferably in well-ventilated sheds.
They may lose up to 25% of their weight during the first month of storage but may be successfully stored for several months at 10 Celsius.
The corms of cultivars with smooth leaf stalks are used as a boiled vegetable; the calcium oxalate crystals present in the corms are removed by extensive boiling. The young petioles are also used as a cooked vegetable.
