Taxonomic remark An accepted genus in Umkomasiaceae according to Novikoff & Barabasz-Krasny, 2015, however Philippe & Bamford, 2008 stated: — type specimen being in contradiction with original diagnosis (authors illustrate cross-fields with three pits whereas both generic and specific diagnosis state “cross-field pits one or two”), and being poorly preserved (authors cannot decipher if cross-field pits are oopores or oculipores, Del Fuyeo et al., 1995: 114), we think this name should not be used before there has been a thorough review of this genus and the material assigned to it. It is probably a taxonomic synonym of Agathoxylon Hartig. [details]
