Taxonomie : "G. leyboldii and “G. woodsonianum” (G. leyboldii var. woodsonianum Markgr.) are sisters. “Gnetum woodsonianum”, endemic to Colombia and Panama (Markgraf, 1965), is currently considered synonymous with G. urens (WCSP, 2014). Our results do not support such a treatment but are more in line with Markgraf’s (1965) opinion that “G. woodsonianum” is a variety of G. leyboldii. However, Markgraf (1965) reports morphological differences between the taxa: G. leyboldii has broadly elliptic leaves, which are smooth and shiny and has inflorescences with 3–4 whorls, whereas the leaves of “G. woodsonianum” are elliptic and not shiny, due to the occurrence of dense subepidermal fibres, and inflorescences have only 1–2 whorls (Markgraf, 1965). Considering these differences, “G. woodsonianum” and G. leyboldii could probably both be treated as species." (Hou et al., Taxon, 64(2): 239-253. 2015).
