Taxonomic remark From Philippe et al., 2019: Protocallitrixylon was described twice as a new genus, first by Yamazaki & Tsunada (1982) and then by Vozenin-Serra & Salard-Chelboldaeff (1992). The first description is validated by a diagnosis generico-specifica (ICBN, art. 38.5) based on P. liassicum Yamazaki & Tsunada. These authors simultaneously described a “sp. A” and a “sp. B”, however since the Sydney Code in 1981 a “monotypic genus” is understood as one for which a single binomial is validly published even though the authors may indicate that other (unnamed) species belong to the genus. Yamazaki & Tsunada described this genus as having araucarian to mixed-type TRP. Independently, Vozenin-Serra & Salard-Chelbodaeff described Protocallitrixylon, but with abietinean TRP and axial parenchyma. [details]
