All Iberian specimens of this genus were revised, and the following taxa were recognised: Bazzania flaccida (Dumort.) Grolle, B. tricrenata (Wahlenb.) Lindb., B. trilobata (L.) Gray and B. trilobata var. depauperata (Mull. Frib.) Grolle. An identification key is presented for these taxa, and morphological characters allowing for distinction between the three species are tabulated. The distribution of each species on the Iberian Peninsula is mapped and illustrations are presented. B. flaccida, previously seldom cited, was found to be rather frequent from the Cantabrian range to the eastern Pyrenees. It had previously been misidentified as B. tricrenata, B. denudata (Torrey ex Gottsche) Trevis. and B. trilobata var. depauperata. B. tricrenata is very rare, and was found only in central Pyrenees and at another isolated locality in Navarra. The distribution of B. trilobata, the most frequent species in the genus, ranges from Navarra to Galicia, Sintra being the only Portuguese reference available; its variety depauperata appeared only once, in Guipuzcoa.
