TheLoganiaceae are afamily offlowering plants classified in orderGentianales. The family includes up to 13genera, distributed around the world's tropics. There are not any great morphological characteristics to distinguish these taxa from others in the orderGentianales.
Many members of the Loganiaceae are extremely poisonous, causing death byconvulsion. Poisonous properties are largely due toalkaloids such as those found inStrychnos.Glycosides are also present asloganin inStrychnos.[2]
Earlier treatments of the family have included up to 29 genera. Phylogenetic studies have demonstrated that this broadly defined Loganiaceae was apolyphyletic assemblage, and numerous genera have been removed from Loganiaceae to other families (sometimes in other orders), e.g.,Gentianaceae,Gelsemiaceae,Plocospermataceae,Tetrachondraceae,Buddlejaceae, andGesneriaceae. Some classification schemes, notablyTakhtajan's, break the remaining Loganiaceae even further, into as many as four families; Strychnaceae, Antoniaceae, Spigeliaceae and Loganiaceae.
Some sources indicate the family consists of 13 genera.[3][4] A more recent study considers someLabordia species synonymous withGeniostoma,[5] resulting in 12 genera in other sources.[6] As of November 2023Plants of the World Online accepts 16 genera:[7]
