Taxonomic remark Substitute name for Homoxylon B. Sahni 1932, non T. Hartig 1848. (Index Nominum Genericorum). Initially suggested to be wood of a vessel-less angiosperm, subsequently assigned to Bennetitales (gymnosperms). However Wang et al., 2009, quoting Zheng et al., 2005 (Global Geology 24: 209-216) claim that Sahnioxylon "mostly represents an evolutionary transition link between the Paleozoic wood Guizhouoxylon and the Late Triassic genus Paradoxoxylon, and is an an ancestral plant type of angiosperms without vessels". From Philippe & Bamford, 2008: Sahnioxylon Bose et Sah ... is validly published despite that no type is designated in protologue as this name was published before 1958 (ICBN, art. 37.1), as a matter of fact in 1955 (and not 1954 as usually indicated).
