Ulva javanica Burman, 1768: 239 (type locality: Java).—C. Agardh, 1823 [1822-1823]: 427.
INDIAN OCEAN DISTRIBUTION: Indonesia (Java).
Note: The identity of this species is unknown. The type, if extant, would be at Genève (G). Merrill (1921: 332–333) suggested that it might be representative of the freshwater genus Chara. It probably came from the north coast of Java and thus not from the Indian Ocean.
