General environment
This is a marine species.

Habitat
In French Polynesia this species forms dense beds down to 20 m depth on exposed reef shelves in the Austral Archipelago (Matteo et al. 2008: 1552).

Type information
Type locality: Oahu, Hawaii (Mattio, Payri & Stiger-Pouvreau 2008: 1552). Lectotype: LD Herb. alg. Agardh No. 02810 (Mattio, Payri & Stiger-Pouvreau 2008: 1552). Notes: Syntype lacality: Sandwich Islands [Hawaiian Islands] (Agardh 1848: 339. According to Magruder (1988:74), a lectotype needs to be selected from J.G. Agardh's specimens (Yoshida 1986, pers. comm.). This was later selected by Mattio et al. (2008: 1552). No. 02811 second series is an isolectotype.
