Studies in Austral Bryaceae (Bryopsida). III. A Preliminary Account with Keys to Rosulabryum J.R. Spence in Chile

A preliminary study of the genus Rosulabryum J.R. Spence in Chile is presented, with brief species descriptions, notes on ecology and distributions, and a taxonomic key. The following 12 species are confirmed with vouchered specimens; Rosulabryumandicola (Hook.) Ochyra, Rosulabryumbillarderii (Schwägr.) J.R. Spence, Rosulabryumcampylothecium (Taylor) J.R. Spence, Rosulabryumcapillare (Hedw.) J.R. Spence, Rosulabryumcoloratum (Müll. Hal.) J.R. Spence, Rosulabryumdensifolium (Brid.) Ochyra, Rosulabryumlongidens (Thér.) J.R. Spence, Rosulabryummacrophyllum (Cardot & Broth.) Ochyra, Rosulabryumperlimbatum (Cardot) Ochyra, Rosulabryumpuconense (Herzog & Thér.) J.R. Spence, Rosulabryumrubens (Mitt.) J.R. Spence, and Rosulabryumtorquescens (Bruch ex De Not.) J.R. Spence. Rosulabryumcanariense (Brid.) Ochyra is tentatively excluded as the Chilean material can be referred to R.coloratum. Similarly, Rosulabryumviridescens (Welw. & Duby) Ochyra is tentatively excluded since the Chilean plants do not match the African type, but instead appear to be atypical plants of R.campylothecium.
