“…Comparison-Our specimens resemble those of Glossopteris tntermedia Feistmantel figured by Maheshwari (1965). Leaves of Glossopteris browlliana are spathulate in shape as compared with linear-Ianceolate or lanceolate spathulate shape of Glossopteris intermedia.…”

“…In apical part the secondary veins bend towards the midrib, run almost parallel to the leaf margins and finish in the margin of the apical portion. Comparison-Our specimens show closest resemblance with GIOssopleris euryneura Maheshwari 1965. This species resembles a Taeniopteris leaf, G. damudica and G. laeniopleroides.…”

“…Diagnosis (after Maheshwari. 1965)-"Leaves Iinearlanceolate or lanceolate-spathulate gradually contracting towards the base into a stalk; apex broadly acute or obtuse; leaves 5-6 times longer than broad; midrib stout,longitudinally striated, continues almost to the apex resolving into finer veins just below the apex; secondary veins arise at acute angles from the midrib and after a gentle arch pass straight to the margins, parallel to one another, dichotomising and anastomosing to form long and oblong-polygonal meshes of almost equal size throughout".…”

The assemblage of fossil plants of Barakar Formation from North Karanpura. South Karanpura and West Bokaro Coal fields contain thirty-two species of the genus Glossopteris. Among these three species are new, twenty-one species are recorded for the first time from the Barakar Formation of South Karanpura, nine species from North Karanpura and eight species from West Bokaro group of coalfields. The range of variation within species have been observed by taking more than one specimens as complex, from different collieries of these three coal fields. The comparison. diagnosis and range of distribution of species in context of other coalfields have also been given. In the present study. the speciation of genus Glossopteris is based on morphography and cuticular features. Here, morphographical characters have been critically analysed in order to find a reasonable basis for precise specific delimitations. Morphographical circumscriptions are further verified by characters of the cuticle wherever available but only as associated or supportive characters.

“…COMPARISON Maheshwari (1965) from Raniganj, India. Indian specimen of G. linearis (MAHESH-WARI, 1965) differs slightly in having petiole but since the present specimen is broken in its basal region, this petiolate condition has not been marked.…”

Five species of Glossopteris (G. cf. G. linearis, G. nidpurensis, G. sp. A, G. sp. B and G. sp. C), Rhabdotaenia sp., Taeniopteris glandulata sp. nov., Noeggerathiopsis sp. and Conites sp. are described here in this paper. Out of these, Glossopteris nidpurensis, G. sp. A, G. sp. B, Rhabdotaenia sp., Taeniopteris glandulata and fragmentary conifer shoots are mainly based on their cuticular characters and remaining ones have been described on their external morphology.

The paper deals with fructifications of glossopterids (viz. Gonophylloides sp., Scutum sp., Ottokaria sp., & Bokarospermum gen. nov.), seeds (Cordaicarpus), bracts and calamitalean axes found in a detached condition from the Barakar Formation of the Karanpura and Bokaro Group of coalfields. Vertebraria axes were also observed from the Rikba plant bed of North Karanpura Coalfield. These mentioned taxa are only a small part of an extensive and significant flora of Karanpura and Bokaro Group of coalfields.
