  • Lathyrus vernus (L.)Bernh. Papilionaceae previously Orobus vernus L. (Linnaeus, 1753) Spring vetchling. Distribution: Europe to Siberia. The seeds of several Lathyrus species are toxic, and when eaten cause a condition called lathyrism. The chemical diaminoproprionic acid in the seeds causes paralysis, spinal cord damage, aortic aneurysm, due to poisoning of mitochondria causing cell death. Occurs where food crops are contaminated by Lathyrus plants or where it is eaten as a 'famine food' when no other food is available. It is the Orobus sylvaticus purpureus vernus of Bauhin (1671) and Orobus sylvaticus angustifolius of Parkinson (1640) - who records that country folk had no uses for it. Photographed in the Medicinal Garden of the Royal College of Physicians, London.

  • Viburnum japonicum Spreng. Caprifoliaceae Distribution: Evergreen Shrub. Distribution: Japan and Taiwan. No medicinal uses. The fruit is a 'famine food' eaten when all else fails. As other seeds/fruits of Viburnum species are listed as poisonous, and none are listed as 'edible', one can assume that the seeds/fruits of V. japonicum are also toxic. It does not appear vulnerable to pests or molluscs which may be due to irioid glycosides that are present in this genus produced as a defence against herbivores, fungi and bacteria. They have a bitter taste. Photographed in the Medicinal Garden of the Royal College of Physicians, London.

  • Camassia leichtlinii (Baker)S.Watson Hyacinthaceae. Great Camas, Quamash. The species was named for Maximillian Leichtlin (1831-1910 of Baden , Germany, bulb enthusiast who corresponded with J.G. Baker at Kew. Bulbous herb. Distribution: North America. The bulbs of Camassia species were eaten by the Native Americans, the Nez Perce, after cooking by steaming for a day - which suggests they may be poisonous raw. They gave them to the American explorers, Meriwether Lewis and William Clerk, on their expedition (1804-1806) when they ran out of food. The bulbs of the similar looking 'Death camus', Toxicoscordion venenosum have been fatal when ingested by mistake (RBG Kew on-line). Steroidal saponins, which are precursors in the manufacture of steroids and cytotoxic activity has been detected in the sap of the bulbs. Photographed in the Medicinal Garden of the Royal College of Physicians, London.
