Lonchocarpus
genus of plants
Lonchocarpus is a plant genus in the legume family (Fabaceae). It includes 166 species native to the tropical Americas, tropical Africa, and Madasgascar. The species are called lancepods due to their fruit resembling an ornate lance tip or a few beads on a string.
Cubé resin is produced from the roots of L. urucu and namely ''L. utilis (cubé). It contains enough of the toxic rotenoids rotenone and deguelin to be used as an insecticide and piscicide. As these are naturally occurring compounds, they were formerly used in organic farming. Since it is highly unselective and kills useful, as well as pest, animals, it is considered harmful to the environment today. Also, chronic exposure to rotenone and deguelin appears to increase the risk of Parkinson's disease, even in mammals, for which these compounds are less immediately toxic than for fish and insects. Deguelin might be useful in cancer therapy if it can be applied directly into tumors, and Lonchocarpus root is used to a probably insignificant extent by indigenous peoples as an aid in fish stunning, e.g. by the Nukak who call it nuún.
The public source identifies “Lonchocarpus” as genus of plants. This brief keeps that definition visible, then builds a research path around Lonchocarpus, genus and plants.
Why this record matters
A short description can identify a subject without explaining its stakes. For “Lonchocarpus”, the useful work is to connect “genus of plants” to the records capable of establishing context and consequence.
The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Jul 6, 2026. The linked authority identifier is Q1756340. None of the 0 selected statements returned an explicit reference.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
