Keywords: Thelypteroidaceae, ecology
Abstract: The Thelypteroid ferns, (24 species and 2 taxa) occur in a wide altitudinal range from sea level upto 2,400m. The species are grouped into two categories depending on their exposure to sun. Most of the species are terrestrial and a few are lithophytes. Christella parasitica and C. dentata are the large species complexes and Pseudocyclosorus ochthodes is a small species complex in South India.

Keywords: Phytochemistry, Thalypteroid ferns
Abstract: Phytochemical studies on nineteen taxa of Thelypteroid ferns of the Western Ghats of South India have been done. The relationship between the amount of pigments such as chlorophylls, carotenoids, anthocyanins and flavonoids and the habitat of the species has been studied. The variation in the amount of pigments with the altitudinal range has been discussed. The relationship between the other primary metabolites with habitat and the altitudinal range has also been discussed.

Subject: Indian Fern Journal
Keywords: Christella parasitica, South India, Morphology, Spores
Abstract: A detailed morphological analysis of 102 gatherings of Christella parasitica (L) Lev from the Western Ghats of South India has been made. The results indicate that each character shows broad range of continuous variations. The variation of each character has been described and discussed separately. In addition, cytological details of this species complex from the area of investigation have also been provided. Nearly one-sixth of the present gathering were seen to be of hybrid origin because of their morphological or cytological irregularities or spore sterility.
The present study from the wild with regard to dominant/ recessive characters in this species complex, is in agreement with Panigrahi & Manton (1958) except the dominant character, the presence of glandular hairs which is yet to be confirmed.

Subject: Indian Fern Journal
Keywords: Palaeoecological, stratigraphical, pteridophytic spores, Kerala basin, Miocene
Abstract: The tertiary sediments of India, in general are replete with pteridophytic spores. The present paper deals with an exhaustive studies of these spores for palaeoecological and stratigraphical significane from the Quilon and Warkalli formations of Kerala Basin, south India. Of the total representation of 135 genera and 175 species, the pteridophytic spores are represented by 31 genera and 64 species. A careful morphotaxonomic study of the dispersed spores and their comparison with the spores of extant genera shows that they are referable to the following families: Schizaeaceae, Adiantaceae, Lycopodiaceae, Parkeriaceae, Polypodiaceae, Cyantheaceae, Pteridaceae, Osmandaceae, Gleicheniaceae, Ophio-glossaceae and Dicksoniaceae. Among these the spores of Schizaeaceae, Polypodiaceae. Adiantaceae and Osmundaceae are dominant in the palyno-assemblage - The presence of pteridophytic spores as a co-dominant constituent of the Quilon and Warkalli assemblages convincingly indicates the prevalence of a tropical climate with heavy precipitation at the time of deposition. From the composition of pteridophytic spores a fresh water palaeoenvironment is inferred. The presence of Crassoretitriletes, Neyvelisporites, Striatriletes, Pteridacidites. Polypodiaceaesporites spp. and Polypodiisporites spp in addition to several other angiospermic pollen genera in the Kerala basin provide a supporting evidence for Miocene age to the sediments studied.

Keywords: Lower Gondwana Pteridophytes, Pteropsida, Sphenopsid, Lycopsid, Glossorpteris
Abstract: Lower Gondwana pteridophytes of India are known by Lycopsid, Sphenopsid and Pteropsida groups of plant. Morphological investigations of different genera and species demonstrate their characteristic features and their significance in taxonomic resolution.
Lycopsid is represented by fewer number of specimens of fragments showing eligulata spirally arranged leaf scars. Sphenopsid is classified into Equisetale and Sphenophyllale on the basis of leaf form and arrangement. Fronds of Pteropsida are established on the basis of sterile and fertile characters of pinnules. The alteration and variations in different forms are discussed with reference to thier taxonomic and stratigraphic positions.

Keywords: Western Ghats, Goa, Ferns, ecology and distribution
Abstract: Present preliminary account of Goa pteridophytes is consequential to our studies on biosystematics of Indian ferns and deals with sixteen species of ferns and one fern ally collected from the Western Ghat of Goa State, South India. Chromosome number of Christella dentata (Forssk) Brownsey & Jermy from this area has been confirmed as n = 72 (4x). Information on the distribution and ecology of the recorded species in the area has been provided. Two endemic ferns namely Althyrium hohenackeranum (Kunze) T. Moore (endemic ot South India and Srilanka) and Bolbitis x Prolifera (Bory) C. Chr & Tardieu - Blot (endemic to south India) have been newly recorded from Goa. All the species are also present elsewhere in the Western Ghats of South India.

Abstract: The epiphytic flora of tropical forests of Western Ghats are inadequately known. Though studies on the pteridophytic flora in the Western Ghats have been undertaken by several authers yet none had attempted so far on the systematic distribution, taxonomy and ecology of epiphytic pteridophytes of Kerala part of Western Ghats. The present paper deals with the systematic distribution of the epiphytic pteridophytes based on the authors own observations and relevant published literature.

Keywords: phytochemistry, chemotaxonomy, ferns, India
Abstract: In the present paper phytochemical studies on Indian ferns have been reviewed. Large number of ferns species have been phytochemically analysed in order to understand ecophysiological adaptations. A good number of medicinal ferns have been analysed phytochemically and parmacognostically. Analysis of secondary metabolites in several Indian ferns resulted in the discovery or record of many new chemical compounds which are very useful in understanding the taxonomic and phylogenetic relationship among Indian ferns.
