ABSTRACT. Type specimens of 75 hepatics taxa currently accepted in Jungermannia, Solenostoma and Plectocolea were studied in the type collection of G. Their systematic position and correct names are discussed. Nomenclature citations (including data from original specimen labels) are presented, most of them are accompanied by morphological descriptions and newly compiled pictures. New lectotypes are selected for Aplozia stephanii Schiffn. and Jungermannia spongiosa Steph. The neotype for Jungermannia thermarum Steph. is designated. Jungermannia danicola Gottsche ex Underw. is synonymized with Solenostoma sphaerocarpum (Hook.) Steph. and Solenostoma purpuratum var. koponenii Bakalin et Li Wei is synonymized with Solenostoma purpuratum (Mitt.) Steph. var. gollanii (Steph.) Bakalin. Fifteen new combinations (Solenostoma papullosum (Steph.) Bakalin comb. nov., Plectocolea callithrix (Lindenb. et Gott.) Bakalin comb. nov., Plectocolea gollanii (Steph.) Bakalin comb. nov., Plectocolea glauca (Amak.) Bakalin comb. nov., Plectocolea montana (Steph.) Bakalin comb. nov., Solenostoma gracillimum var. heteromorpha (Gott. et Rabenh.) Bakalin comb. nov., Plectocolea decolor (Schiffn) Bakalin comb. nov., Plectocolea newellana (Steph.) Bakalin comb. nov., Plectocolea renauldii (Steph.) Bakalin comb. nov., Plectocolea sexplicata (Steph.) Bakalin comb. nov., Plectocolea dusenii (Steph.) Bakalin comb. nov., Plectocolea obliquifolia (Schiffn.) Bakalin comb. nov., Plectocolea vulcanicola (Schiffn.) Bakalin var. tenuiretis (Schiffn.) Bakalin comb. nov., Plectocolea vulcanicola (Schiffn.) Bakalin var. tenuiretis (Schiffn.) Bakalin f. cavifolia (Schiffn.) Bakalin comb. nov., Solenostoma purpuratum (Mitt.) Steph. var. gollanii (Steph.) Bakalin comb. nov.) are proposed. The species status of Solenostoma marcescens (Mitt.) Bakalin and Plectocolea yunnanensis Bakalin is confirmed.
