Nomenclatural notes
As the cited basaionym, Fucus membranaceus Stackhouse is illegitimate, Batters's name may be treated as a new name. - (27 August 2015) - M.D. Guiry
"In attempting to integrate the foregoing nomenclatural information with Nizamuddin's classification, I encountered difficulty resulting from that author's practice of basing nomenclature at least partly on circumscriptions. Thus, he recognized as distinct species Dictyopteris polypodioides (Desfontaines) Lamouroux and D. polypodioides [sensu] Lamouroux. For the species that he called D. membranacea (Stackhouse) Batters, the synonymy, after being purged of circumscriptions, includes F. membranaceus Stackhouse 1795 (illegitimate), F. polypodioides Desfontaines 1799 (illegitimate), Ulva polypodioides De Candolle 1805 (legitimate), and Dictyopteris elongata Lamouroux 1809 (legitimate). The correct name for this species is thus D. polypodioides (De Candolle) Lamouroux, despite the fact that according to Nizamuddin, Lamouroux did not have this species in hand when he made the combination. Art. 7.4 requires a combination to remain with the basionym regardless of the identity of the material in the hands of the author who made the combination. For the species that Nizamuddin called D. polypodioides Lamouroux, the synonymy, after being purged of misapplied names, includes only D. polypodioides (De Candolle) Lamouroux var. angustifrons Montagne (1846b: 29). This species thus remains without a name." (Silva in Silva, Basson & Moe, 1996: 927). - (27 August 2015) - M.D. Guiry

Taxonomic note
"Nizamuddin%u2019s (1981) taxonomic conclusions are questionable due to the possible confusion between sori and hair tufts, at least for specimens by Nizamuddin ascribed to D. membranacea and to D. tripolitana. Such an opinion was expressed by both Silva et al. (1996: 924-927) and Phillips (2000), who stated that Nizamuddin%u2019s (1981) taxonomic conclusions should be confirmed." (Cormaci et al. 2012: 46). - (27 August 2015) - M.D. Guiry
