Abstract

Oncodostigma Diels (1912: 143) was erected by Diels (1912) based on the type species O. leptoneura Diels (1912: 143). Five additional species were subsequently added to the genus, viz.: O. wilsonii Guillaumin (1931: 224), O. monosperma (Hooker & Thomson 1872: 57) Sinclair (1951: 605), O. mindorense (Merrill 1907: 273) Bân (1974: 1779), O. hainanense (Merrill 1925: 131) Tsiang & Li (1979: 81) and O. microflorum Okada (1996: 8). Van Heusden (1992) conducted a detailed comparative study of the floral morphology of Annonaceae and noted that Oncodostigma is not clearly distinct from Meiogyne Miquel (1865: 12). She subsequently transferred O. mindorense and O. monosperma to Meiogyne and reduced O. wilsonii to synonymy with M. cylindrocarpa (Burck 1911: 433) Heusden (1994: 499). The name Oncodostigma hainanense (Merrill 1925: 131) Tsiang & Li (1979: 81) had previously been transferred to Meiogyne by Bân (1973).
