Distributional notes
Chiang, Y.M. (1997: 167, 168) refers to the Hypnea charoides-valentiae complex and notes that many intermediate forms are found in Taiwanese waters. Lewmanomont (1997: 187) also refers to the above complex and notes "this species is rather common in the Gulf of Thailand".

General environment
This is a marine species.

Yamagishi & Masuda (1997: 140, 141) note that among plants growing in Japan, no clear-cut differences between H. charoides and H. valentiae are found and they treat these as a H. charoides-valentiae complex.

Found under moderate wave action and commonly epiphytic on Amphibolis (Womersley 1994: 443).

Type information
Type locality: "Nov. Holl." (Silva, Basson & Moe 1996: 295). Notes: According to Womersley (1994: 443) the type is apparently lost (not found in CN) and until it is found, Lamouroux's illustrations must serve to lectotypify the species. He notes that the type may have been collected by one of the early French expeditions, that of D'Entrecasteaux (1791-1794) or Baudin (1800-1804), and must have come from south-western or south-eastern coasts of Austalia. According to Silva et al. (1996: 296), it would be useful to select an epitype in accordance with Art. 9.7 in support of Womersley's interpretation of Lamouroux's illustrations.
