Abstract:Species nova S.falcatulo Besch.affinis,sed foliis caulinis latis，triangulo—lingulatis efibrosis，cellulis hyalinis leviter sepatis；foliis ramulinis ovatis vel oblongo—ovatis，apice plerumque apiculatis；porosis cellularum hyalinarum paucioribus tantum in angulis obsitis;cellulis chlorophylliferis in sectionibus transveralibus late triangulibus，dorso folii sitibus，facile differt．
