抄録

1. The present paper deals with the cytotaxonomical investigations of a terrestrial species of Oedogonium viz. O. pakistanense Islam and Sarma.
2. The detailed morphological characters of this material is very closely allied to O. pakistanense as reported by Islam and Sarma (1963) from Dacca and so this species has been reported for the first time from India.
3. The sequence of nuclear division in O. pakistanense follows the usual Oedogonialean pattern.
4. Original mitotic chromosomes count of n=17 is obtained for the first time in a terristrial species of Oedogonium viz. O. pakistanense Islam and Sarma.
5. Godward's (1948) iron-alum acetocarmine technique has been employed through out the present investigation for cytological studies.
