Type species
This is the type species (lectotype) of the genus Jania.

Status of name
This name is of an entity that is currently accepted taxonomically.

Corallina rubens Linnaeus

Type information
Type locality: ‘Insulae Stoechades’ [Îles d’ Hyères, France, Mediterranean], (Linnaeus 1758: 806). Lectotype: collector unknown; UPS herb. Burser; vol. XX: 72 (Irvine & Chamberlain 1994: 56). Notes: "In the protologue, Linnaeus (1758, p. 806) indicated ‘Habitat in Oceano Europæo’. Whether this includes the Mediterranean is uncertain because, for other species, Linnaeus (1758, pp. 131, 283, 815, 819, for example) cited ‘Habitat in M. Mediterraneo’. The type locality was erroneously listed as the ‘Atlantic coast of Norway’ by Millar and Kraft (1993, p. 14)." (Harvey, Woelkerling & Reviers 2020: 269).

Origin of species name
Participle (Latin), reddish (Stearn 1973).

Nomenclatural notes
Athanasiadis (2016: 350) credits Lamouroux (1812: 185 [actually 186]) with this combination but the binomial was not formally used by Lamouroux in this publication. - (3 Feb 2017) - M.D. Guiry

Taxonomic notes
John et al. (2004) cite Jania corniculata (L.) J.V. Lamour as a synonym of this species.

General environment
This is a marine species.

Common names

(as Jania rubens (Linnaeus) J.V.Lamouroux)
English: Slender-beaded Coral Weed (Bunker & al. 2010).

Slender, rose-pink, articulated, calcified fronds, to 50 mm high. Repeatedly dichotomously branched, luxuriant specimens secondarily pinnate. Segments cylindrical, to 120 µm diam., those bearing branches somewhat compressed, to 180 µm diam. Fixed by small conical disc, but spreading vegetatively by developing attachment discs from branches in contact with solid substratum.

Epiphytic, found only growing epiphytically on the brown algae Cladostephus and Cystoseira lower intertidal, southern and western shores of Britain and Ireland, often abundant. It does not grow directly on rock in Britain or Ireland.

Similar species
Corallina elongata, which is pinnately branched in contrast with the dichotomous branching of Jania rubens.
