Family ULVACEAE

Ulva fasciata Delile, 1813 Cryptogenic

While Hewitt et al. (2004) treated this species – perhaps in reality a species complex – as introduced to Australia from the Mediterranean, it (unlike Cladophora prolifera perhaps) is now too widespread to determine its origins [for example, Ulva fasciata is said to be the commonest species of Ulva in the Hawaiian Islands, where Cladophora prolifera is not recorded ( Abbott and Huisman 2004)]. Aguilar-Rosas et al. (2005) consider it introduced to Mexico; Carlton and Eldredge (2009) consider it cryptogenic in Hawaii. Stegenga et al. (1997) report it as occurring from False Bay to tropical East Africa, noting that it is considered a pantropical species.
