A nomenclatural reassessment of some of Bliding’s Ulvaceae

Attention is called to Ulvaceae invalidly described by Bliding in 1960 and 1963, due to his failure to indicate Types. The following new taxa Ulva croatica, Ulva mediterranea, Ulva splitiana, Ulva flexuosa var. linziformis, Ulva linzoides, Ulva blidingii, Ulva flexuosa [subsp. paradoxa] var. profunda and Ulva prolifera subsp. blidingiana to replace the invalid names Enteromorpha adriatica, Enteromorpha aragoënsis, Enteromorpha jugoslavica, Enteromorpha linziformis, Enteromorpha stipitata var. linzoides, Ulva neapolitana, Enteromorpha flexuosa [subsp. paradoxa] var. profunda and Enteromorpha prolifera subsp. gullmariensis respectively, are proposed. Moreover, the conspecificity between Enteromorpha multiramosa Bliding nom. inval. (= Ulva multiramosa Taskin) and Ulva polyclada Kraft is proposed.
