Basionym: Cystoseira aurantia Kützing, 1843: 357 . Phycologia generalis……Leipzig XXXII+458 pp, 80 pls.

Homotypic synonym:

Cystoseira barbata f. aurantia (Kützing) Giaccone in Amico et al. (1986: 906). Un nuovo approccio allo studio della sistematica del genere Cystoseira C. Agardh (Phaeophyta, Fucales ). Bollettino dell’Accademia Gioenia di Scienze Naturali di Catania, 18(326): 887–988.

Note: in absence of molecular evidences, we here consider G. barbata f. aurantia from Mediterranean as a distinct taxon from C. barbata f. repens Zinova et Kalugina [= G. barbata f. repens (Zinova et Kalugina) Sadogurska ] described for the Black Sea, due to its morphological characters rather different from those of Zinova et Kalugina’s taxon as described and illustrated by Sadogurska (2021: 301, Fig 3 ), particularly due to the presence of short primary axis in f. repens (not present in f. aurantia ) and both lateral and ultimate branches in f. repens (neither lateral nor ultimate branches distinguishable in f. aurantia ) (see Sadogurska, 2021: 301, Fig 3a and Cormaci et al. 2012 tav 93 fig 1, respectively).
