Solanum linnaeanum

Solanum linnaeanum is a nightshade species known as devil's apple and, in some places where it is introduced, apple of Sodom. The latter name is also used for other nightshades and entirely different plants elsewhere, in particular the poisonous milkweed Calotropis procera.[1]

Unripe fruit and thorns

This poisonous plant bearing tomato-like fruit is native to many african countries Kenya,Tanzania,South Africa,[2] Zimbabwe and Mozambique,[3] and is considered to be an invasive species in Australia,[4] New Zealand,[5] Hawaii, Fiji, New Caledonia, other Pacific Islands, the Aseer region of Saudi Arabia, and northern areas of Pakistan.[6]When raw its fruits are green and look exactly like the Thai eggplant and when ripe they are yellow. In Ukambani eastern Kenya children in the villages in summer season use the poisonous yellow fruit as football cautiously,wisdom passed through generations.

Solbec Pharmaceuticals attempted to develop Coramsine,[7] a 1:1 mixture of the alkaloids solamargine and solasonine extracted from Solanum linnaeanum, as a cancer drug. Preliminary clinical trials were initially promising,[8] but the drug was ultimately unsuccessful.

Solanum linnaeanum may be confused with Solanum cinereum (Narrawa burr) in Australia,[3] the neotropical Solanum capsicoides,[3] or Solanum incanum in Africa.

Synonyms

Due to confusion about what species the original Solanum sodomeum of Carl Linnaeus referred to (most recently, it was identified as Solanum ferox), the old description was discarded and the plant redescribed as currently understood. A new taxon honoring Linnaeus was chosen. A number of invalid taxa have thus become attached to the devil's apple:[9]

  • Solanum astrophorum Jan (nomen nudum)
  • Solanum hermannii Dunal
  • Solanum mccannii Santapau
  • Solanum sodomeum L. (disputed)
  • Solanum sodomeum var. hermannii (Dunal) Dunal
  • Solanum sodomeum var. mediterraneum Dunal
  • Solanum undatum Bouton ex Dunal (preoccupied)
Solanum undatum as described by Walsh is Solanum lycocarpum.
Solanum undatum var. violaceum, described by Dunal in de Candolle, is the original Solanum aethiopicum of Linnaeus.

It is not clear whether the plant described by Drège as Solanum sodomeum was of this species. Solanum sodomeum by Russ based on Nees von Esenbeck is another nomen nudum.[9]

gollark: PotatOS was never advertised on the CC forums due to things also.
gollark: The potatOS of today is quite different to the potatOS of 2018 though.
gollark: PotatOS was created in late 2018.
gollark: Impressive.
gollark: It's documented now.
