Note: The name Ulva latissima Linnaeus (1753: 1163; type locality: "in Mari Europae'') has traditionally been misapplied to representatives of the genus with very broad, sheet-like fronds, whereas the type is referable to Laminaria saccharina (Linnaeus) Lamouroux (1813: 42) (Fucus saccharinus Linnaeus, 1753: 1161; type locality: Atlantic Ocean) (see P. Silva, 1952a: 295–296 and Papenfuss, 1960: 303). While European records apparently are referable to Ulva gigantea (Kützing) Bliding (1969: 558–562) (Phycoseris gigantea Kützing, 1843b: 289; type locality: Rügen Island, Germany), Indian Ocean references probably belong elsewhere (see Ulva indica Roth (q.v.)).
