Frullania tuyamae Hatt. & Thaith. (Hepaticae) from Manipur (Eastern India)-New to India

While investigating the Hepaticae of Manipur State (23°47'-25°41' N and 93°61'-94°43' E) collected during February-March 1978, the presence of an interesting species of Frullania was noticed. The point of interest centered round the numerous gemmae borne on the margins of dorsal leaf-lobes, a rare feature for the genus Frullania. This plant resembles Frullania tuyanae Hatt. & Thaith., a species recently instituted by Hattori and Thaithong (1978) from Laos. The species so far endemic to Laos is being reported for the first time from India. The present species of Frullania is distinctive from all other known species from India in having numerous gemmae restricted to the margins of leaf-lobes and leaf-lobules. The relevant taxononic features of the plant are given below.
