Order Ralfsiales

Ralfsiales Nakamura ex P.-E.Lim & H.Kawai in Lim et al, 2007: 464.

Type of name: Ralfsiaceae

Source: Huisman, J.M. (2015). Algae of Australia: marine benthic algae of north-western Australia. 1. Green and brown algae. pp. [i]-viii, 1-320, 56 figs, 14 pls. Canberra & Melbourne: ABRS & CSIRO Publishing.

Original publication: Lim, P.-E., Sakaguchi, M., Hanyuda, T., Kogame, K., Phang, S.-M. & Kawai, H. (2007). Molecular phylogeny of crustose brown algae (Ralfsiales, Phaeophyceae) inferred from rbcL sequences resulting in the proposal for Neoralfsiaceae fam. nov.. Phycologia 46(4): 456-466, 1 fig, 3 tables.

Description:
Emended by Lim & Kawai (Lim et al. 2007: 464): The thallus crustose in at least one of the life history stages, or in the early stages of development, with disc-type germination; having one to several chloroplasts without pyrenoids in each cell; unilocular zoidangium with or without paraphyses; intercalary plurilocular sporangium with sterile terminal cell(s). <i>rbc</i>L gene sequences distinct.

Taxonomic notes:

Lim et al. (2007) note that Nakamura (1972) provided no Latin description/diagnosis, so the name Ralfsiales did not fulfill the requirements of the International code of Botanical Nomenclature. Lim et al. provide a Latin description/diagnosis on page 464.
