Acacia microcephala Graham, in N.Wallich, Numer. List no. 5263 (1831-32)
Name Status. Non-Current Name
Name Type. Nom. nudum Source. Kurz (1877)
Accepted Name. Vachellia leucophloea var. microcephala (Kurz) Maslin, Seigler & Ebinger
Notes. Maslin et al. (2013: 43): Kress et al. (2003: 299) list this name for an entity from Myanmar, citing its distribution and common names within that country, and describing the plant simply as a ‘Tree’. The name A. microcephala Graham first appeared in Wallich Num. List [Wallich] n. 5263 (1831-1832). Names on this list are regarded being effectively published but are to be treated as nomina nuda unless a subsequent combination cites (or infers) a basionym, in which case they are considered to be validly published (Forman 1997). We consider the Kress et al. (2003) listing of A. microcephala Graham as a nomen nudum. Besides, even if it were regarded as having validly published it would be a nom. Illeg. Because it would be a later homonym on account of A. microcephala Macfadyen (1837). The taxon to which Kress et al. applied the name A. microcephala is perhaps A. leucophloea var. microcephala Grah. ex Baker in Hook.f., Fl. Brit. India 2 (1878) 294; the latter name is possibly an isonym of A. leucophloea var. microcephala Kurz (1877: 297) which is the basionym of Vachellia leucophloea var. microcephala.
