Cytological observation on some South Indian species of Macromitrium Brid

Cytological studies were carried out on four South Indian moss taxa. All four taxa, Macromitrium calymperoideum (n=12), M. moorcroftii (n=ll), M. perrottetii (n = 12) and M. sulcatum (n=11+ m) have received cytological attention for the first time. The largest bivalent in the chromosome complement of two taxa, i.e. Macromitrium perrottetii and M. sulcatum was found to be heteromorphic. An anaphase-II bridge (Macromitrium calymperoideum) and telophasic bridge (M. perrottetii) were also observed. A triad was found in Macromitrium sulcatum.
