ABSTRACT |
Monosporus indicus Bφrgesen was collected for the first time in Korea. The morphology and reproductive structure were investigated with field and laboratory cultured materials. The species was clearly distinguished among Monosporus by the characters, the cellulosympodial development of thallus, alternately branched main axis, and the thallus providing prostrate and erect axes by its strong decumbent habit. Pedicellate monosporangia did not liberated monospores but fell off themself by degeneration of pedicel. Monosporangia germinated directly and grew identically as the mother plants. During laboratory culture, such an asexual reproduction was repeated three times without any sexual structure. Although we accepted Monosporus as a form-genus under the Griffithsieae, the species was unique enough to separate it from other genera in the tribe. We provisionally retain ti under Monosporus until sexual reproduction to be clarified.
