Abstract

The spore germination, protonemal development, and gametophyte differentiation of Hypnum pacleseens were observed in cultivation. Photomicrographs showed that spore germination of Hypnum pacleseens occured within the exospore. Its protonema is massive with filamentous chloronema formed inside. The terminal part of the chloronema differentiated into filamentous caulonema and its rhizoid was derived from the apical cell of the filamentous chloronema. The initial cell of gametophyte differentiated from chloronema and caulonema. Sporeling-type of Hypnum pacleseens is developmentally similar to Glyphmitrium-type.
