    Abstract

    An illustrated account of 71 desmids from perennial streams of

    Bandhavgarh, one of the important national parks of the country,

    is g iven . t o forms marked with an asterix are recorded for the first

    time from India .

    Introduction

    Bandhavgarh is famous for its historical background and

    stands on a hill at an elevation of 823 meters, about 129

    kilometers from Rewa on the Rewa-Umaria road, 32

    kilometers from Umaria Railway station of South Eas-

    tern Railway. Presently it is one of the most important

    national parks in the country .

    There are many hilly streams which are more or less

    perennial in nature and also a few tanks atop of the hill .

    Algal flora of the place is very rich but has not attracted

    the attention of naturalists . The place was visited from

    time to time by two of us (MSA &RD) for making algal

    collections during the year 1972-'73 . Dikshit & Agarker

    (1974) have enumerated the algae of Bandhavgarh in-

    cluding a few desmids . In the present communication a

    detailed and illustrated account of desmids has been

    given . to desmids marked with an asterix have been re-

    corded for the first time from India .

    The following abbreviations are used in the text and

    dimensions are given in microns . All the dimensions are

    including spines and processes .

    L - length ; W - width ; T - thickness ; I - width of isthmus ;

    P - pole .
