摘要:
A detailed investigation ofRodeitesSahni from nearly 100 specimens collected from the Deccan Intertrappean beds of India has brought to light some new important facts: (1) The sporocarp wall is thicker and the spores within it are larger than hitherto described. (2) The mode of sorus attachment, observed for the first time, is similar to that ofMarsilearather thanRegnellidium.(3) The presence of a distinct cellular gametophyte inside some megaspores is an entirely new finding for the family Marsileaceae. The presence of a male prothallus inside smaller microspores is also newly observed. (4) The occurrence of sporocarps in groups and their attachment are unique. (5) The prismatic layer is distinct in the sporocarp wall ofRodeitesThe above observations help in reconsidering the position ofRodeitesin the Marsileaceae.
