--><p>Strychnos is the largest genus in Loganiaceae. Its species are found in tropical rainforests and savannahs in both the Old World and New World Tropics, with the greatest number in tropical Africa. Alkaloids are prevalent in Strychnos species (N. G. Bisset and J. D. Phillipson 1971), the best known being strychnine, which is commercially extracted from the southeastern Asian S. nux-vomica Linnaeus. Some American species have been used as the primary or secondary ingredients in the dart poison curare (B. A. Krukoff and J. Monachino 1942; Krukoff and R. C. Barneby 1969); medicinal uses have been reported for Old World species (H. M. Burkill 1985–2004).</p><!--
--><p>Brehmia Harvey (1842), a later homonym of Brehmia Schrank (1824), pertains here.</p>
