Strychnos
Strychnos is a genus of flowering plants, belonging to the family Loganiaceae (sometimes Strychnaceae). The genus includes about 100 accepted species of trees and lianas, and more than 200 that are as yet unresolved.[1] The genus is widely distributed around the world's tropics and is noted for the presence of poisonous indole alkaloids in the roots, stems and leaves of various species. Among these alkaloids are the well-known and virulent poisons strychnine and curare.
The name strychnos was applied by Pliny the Elder in his Natural History to Solanum nigrum. The word is derived from the Ancient Greek στρύχνον (strúkhnon) – "acrid", "bitter". The meaning of the word strychnos was not fixed in Ancient Greece, where it could designate a variety of different plants having in common the property of toxicity.[2]
The genus is divided into 12 sections, though it is conceded that the sections do not reflect evolution of the genus, and all sections except Spinosae are polyphyletic:[3]
