When establishing the new generic name on the basis of “Nathorst’s name Pityostrobus”, a designation applied by Nathorst (in Kongl. Svenska Vetensk. Acad. Handl., ser. 2, 30(1): 62. 1897) without description to one of his provisional morphotaxon subdivisions of Pinites, Dutt (l.c.) appears to have overlooked the fact that he definitely included in Pityostrobus the type of the earlier validly published generic name Zamiostrobus, Z. macrocephalus, and, therefore, according to Art. 52.1 & 52.2, his new generic name was a superfluous, illegitimate synonym of Zamiostrobus. Doweld (in Taxon 62: 842-843. 2013) proposed the conservation of the generic name Pityostrobus C.P. Dutt 1916 against Zamiostrobus Endlicher, Gen. Pl.: 72. Aug 1836.
