Decaisnea, known commonly as dead man's fingers, is a genus of flowering plant in the family Lardizabalaceae. It is native to eastern Asia, from China west to Nepal and south to Myanmar. The genus comprises one or two species, depending on taxonomic opinion. Decaisnea insignis (Griffith) Hook.f. & Thomson was described from Nepal, and is sometimes restricted to the plants occurring in the Himalaya, with Chinese plants distinguished as Decaisnea fargesii Franchet. The only cited distinction between the plants from the two regions is the fruit colour, yellow-green in D. insignis and bluish in D. fargesii. This is of little significance and the two are now combined under the older name D. insignis by some authors.
