The leaf form genus Euryphyllum Feistmantel 1879 is known by two species, viz., E. whittianum Feistmantel 1879 E. obovatum Maithy 1970 from the Karharbari bed of Giridih Coalfield, India. Both these species are based on the external morphology only. For the first time epidermal features of this leaf are reported from the Early Permian beds of Talchir Coalfield and a new species– E. maithyi has been established. Besides, three specimens assignable to the type species of the genus E. whittianum are also recorded. All the specimens hitherto described and or transferred under this leaf genus have also been re-examined alongwith its possible affinities and affiliation.
An attempt has been made to reconstruct the plant of Neomariopteris hughesii based on fifty-five hand specimens collected from the Barakar Formation exposed near Brijraj Nagar Railway Station in the Ib-River Coalfield, Orissa. The limitations of this reconstruction have been realised by the authors as the main trunk of the plant and the fertile structures are not recorded from this very location, however, combined evidence put together from other sources as well suggests that this fern plant could be a small tree based on branched stems of considerable length and width rather than a usual prostrate fern habit. An up-to-date list of all the specimens recorded under the genus Neomariopteris and its six species by various workers from different localities and formations or India has also been given.
A new genus Handapaphyllum is established for fan-shaped, petiolar leaves having symmetrically lobed and dissected lamina with 6-8 dichotomous parallel running veins from the Kamthi Formation of Handapa, Orissa.
Benlightfootia Lacey & Huard-Moine has been reported from the Kamthi Formation of Belpahar area, Ib-River Coalfield, Orissa. It is characterised by non-petiolate, cordate, bifid leaves having a deep apical notch. The venation is open, dichotomous, arising from a single thick vein at the base of the leaf. A new species, B. indica has been proposed.
Fossil plant asssemblages around Marhwas area in Sidhi District are represented by one species each of Trizygia, Neomariopteris and Scutum, a fern and 24 species of Glossopteris. Floristic composition indicates Raniganj-Kamthi affinities and a warm-temperate climate. High percentage of small-sized leaves and poor representation of pteridophytes in the flora suggest drier conditions and low humidity.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
