Encephalartos ferox
Safety & Hazards
We have no specific information for this species, but most if not all members of this genus are believed to contain toxins. The two main toxic compounds that have been identified are cycasin and macrozamin. When ingested in sufficient quantities, these compounds are extremely poisonous to humans and many other animals, and have been shown to cause liver damage and cancer. Cycasin and macrozamin have a cumulative effect upon the body and are suspected of causing neurological disorders when ingested in small amounts over long periods of time. There is a long history of human use of this genus as a starch-rich food, but it should be noted that the plants needed to be treated in various ways in order to remove any toxic principles. Caution should be exercised even with properly prepared foods, since even then regular consumption may lead to severe health problems and death. Since many of these species are becoming increasingly rare in the wild, this is probably a food best left to times of food shortage when other, better foods, are not available[ 1935 Title The Cycads Publication Author Whitelock L.M.

Botanical Description
Encephalartos ferox is an evergreen, palm-like plant producing a short, mainly subterranean stem that sometimes develops into an unbranched aerial stem 100 - 200cm tall and 30 - 35cm in diameter. It produces a crown of many, spreading leaves 100 - 220cm long. The plant is usually solitary, but occasionally produces suckers from the base to form a clump[ 1935 Title The Cycads Publication Author Whitelock L.M.

There are detailed descriptions and a host of other information for each species. ]. Generally, the stems of this species are subterranean as a result of the action of their contractile roots, but in the northern limits of its range in Mozambique, stems up to 2 metres long are not rare[ 1935 Title The Cycads Publication Author Whitelock L.M.

It is a very attractive plant that is often grown as an ornamental[ 338 Title IUCN Red List of Threatened Species Publication Author Website http://www.iucnredlist.org/ Publisher Year 0 ISBN Description A list of plants under threat and facing possible extinction, usually with brief details of the threats and information on habitat. ]. Large populations of Encephalartos ferox occur from northern KwaZulu-Natal in South Africa to at least as far north as Inhambane in Mozambique. However, this species needs to be monitored as numerous plants have been removed and sold alongside roads in Mozambique and large tracts of habitat have been destroyed. The plant is classified as 'Near Threatened' in the IUCN Red List of Threatened Species(2013)[ 338 Title IUCN Red List of Threatened Species Publication Author Website http://www.iucnredlist.org/ Publisher Year 0 ISBN Description A list of plants under threat and facing possible extinction, usually with brief details of the threats and information on habitat. ].
