Unripe fruit and thorns

Solanum linnaeanum is a nightshade species known as Devil's Apple and in some places where it is introduced as "Apple of Sodom". The latter name is also for other nightshades and entirely different plants elsewhere.

This poisonous plant bearing tomato-like fruit is native to South Africa,[1] Zimbabwe and Mozambique,[2] and is considered to be an invasive species in Australia,[3] New Zealand,[4] Hawaii, Fiji, New Caledonia, and other Pacific Islands.[5]

Solbec Pharmaceuticals attempted to develop Coramsine,[6] a 1:1 mixture of the alkaloids solamargine and solasonine extracted from Solanum linnaeanum, as a cancer drug. Preliminary clinical trials were initially promising,[7] but the drug was ultimately unsuccessful.

Solanum linnaeanum may be confused with Solanum cinereum (Narrawa burr) in Australia,[8] the neotropical Solanum capsicoides,[9] or Solanum incanum in Africa.

Synonyms[edit]

Due to confusion about what species the original Solanum sodomeum of Carl Linnaeus referred to, 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:[10]

  • Solanum astrophorum Jan (nomen nudum)
  • Solanum hermannii Dunal
  • Solanum mccannii Santapau
  • Solanum sodomeum L.
  • 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.[10]
