Abstract: Indian quillworts form an important constituent of the pteridophytic flora of India. They exhibit a fairly wide range of morphological diversity and are found distributed in different geographical regions extending from the sea level to higher altitudes. To date fifteen species, three sub species and three varieties of the genus Isoetes L are reported. The present paper is a brief but critical review of the Indian quill worts with reference to thier morphology and taxonomy.

Abstract: The variant of the polymorphic species Lindsaea heterophylla Dryand, is taxonomically treated in several ways. The free veined plant of this species is ocnsidered as a local variety or as a different species or conspecific with L. heterophylla. In the present observation it is concluded that the free veined plant of this species is an altitudinal ecotype.

Abstract: Pteridophytes, the seedless vascular cryptogams which occupy a position between the lower non -seed bearing and higher seed bearing plants from a generally much neglected group of plants as far as their economic value is concerned. But the ethnobotanical uses of this unique group are very many. It is right that, though not all, but many species of ferns and fern-alllies are of immense economic utility, which is manifold. The most important are their aesthetic, food and medicinal values. Young leaves of the ferns Diplazium esculentum (Retz) Sw, Helminthostachys zeylanica (L) Hook., Nephrolepis cordifolia (L) Presl and Stenochlaena palustris (Burm) Bedd. are cooked as vegetables by the tribals in Indian mountains. Azolla pinnata R. Br is used as rice fertilizer and chicken feed. In the case of water fern Marsilea drummondii the starchy paste of the sporocarps is made in to cakes called ' Nardoo ' and is eaten by the natives of Australia. The spores of the club moss Lycopodium Linn. are rich in fat and those of L. clavatum L. contain 50% oleic glyceride. These are used in pharmacy as water repellent and protective dusting powder for tender skin. Selaginella bryopteris. Bak. and S.adunca A Br. ex Hieron are markedly xerophytic and have got extraordinary powers of recovery after prolonged drought, these are sold as curiosities under the name, ' resurrection plants ' . Members of the genus Equisetum Linn., ' the horse-tails ' or the ' scouring rushes ' as they are called were once much used for polishing woods and scouring utensils. E. arvense Linn. indicates speical affinity for gold and is generally known as ' gold indicator ' , where it grows. Therefore, such species are of importance in prospecting for new ore deposits. The leaves of the lindsaeoid fern sphenomeris chinensis (Linn) Maxon are used to produce red dye. Similarly the rhizomes of the ' bracken fern ' Pteridium aquilinum (L) Kuhn are used for producing dark yellow dye. Fibres obtained from some ferns as Osmunda Linn. and Cibotium Kaulf are used for making mats, baskets and stuffing and packing materials. Certain ferns as Angiopteris evecta (Forst) Hoffin., Adiantum capillus-veneris Linn., Polypodium phymatodes Linn. and P . vulgare Linn are used for fragrance and flavourings. Tree ferns are used as timber in some countries.
Ferns, the flowerless plants have got aesthetic value due to their grace and delicate beauty and are cultivated as ornamental plants. The ferns can grow well in such moist and shady situations in the gardens where other plants generally can not grow. Ferns which are generally grown in the gardens are houses as potted plants for aesthetic purposes are Equisetum diffusum D. Don, Angiopteris evecta (Frost) Hoffm., Osmuda regalis Linn., Microsorum punctatum (L) Copel., Lygodium flexuosum (L) Sw., Pteris vittata Linn., Adiantum capillus - veneris Linn., A. incisum Frosk., Cyathea spinulosa Wall. ex Hook., Ampelopteris prolifera (Retz) Copel., Christella dentata (Frosk) Browns & Jermy, Pronephrium nudatum (Roxb ex Grif) Holtt., Asplenium nidus Linn, Diplazium esculentum (Retz) Sw., Tectoria macrodonta (Fee) C. chr ., Nephrolepis cordifolia (L) Presl N exaltata (L) Schott., Azolla pinnata R. Br., Salvinia natans (L) All, etc.
Quite a number of ferns and fern allies are of great medicinal value, amongst them mention may be made of Equisetum arvense Linn. which is used in nasal polypus and kidney infections, ashes useful in acidity. E. debile Roxb, is diuretic and given in gonorrhoea. Lycopodium clavatum Linn., in the form of decoction used in rheumatism and diseases of lungs and kidneys. The past of the leaves of Ophioglossum reticulatum Linn., is used in headache. Botrychium virginianum Sw is used in dysentery. Helminthostachys zeylanica (Linn) Hook is used for vitality and brain tonic. Lygodium flexuosum (Linn) Sw., is expectorant and used in ulcers, cutwounds and sprains. The fronds of the gleicheniaceous fern Dicranopteris linearis (Burm). Underwood are used for ashtma and in woman ' s sterility. The plants of the ' royal fern ' Osmunda regalis Lilnn. are styptic and tonic. The rhizomes of Angiopteris evecta (Forst) Hoffm are used for scabies. There are many other ferns which are of immense medicinal value and are discussed.

Subject: Indian Fern Journal
Keywords: Fungal, association, extinct, extant ferns, fernallies
Abstract: The present account concerns the mycorrhizic association with extinct and extant pteridophytes. Symbiosis was common during the Early Devonian Period while adaption to the land habit was in progress. In pteridophytes the association exists in both the sporophytic and gametophytic phases of the life cycle. Aquatic plants like Isoetes tuberculata and Salvinia cucullata also, have mycorrhizic symbiosis. Importance of the fungal association in early evolution of vascular plants is discussed.

Abstract: Regular removal of garbage, solid waste management and pollution control are the basic problems in urban areas of India. Urban planning and design along with urban vegetation cover are is on the wane. On the other hand in western countries cities like Vienna of Austria Central Europe, where the author had the chance to stay in July 2005, have got a clean and green environment. City has lot of lofty buildings, but has also areas with grass green vegetation particularly in churchyards, institutions, streets, squares adn cemeteries. During respite hours of the days passed in Vienna the author has felt the need of urban greening in India. Pteridophytic vegetation has to get sequential role in urban greening, landscape planning and nature conservation in India likewise in central European countries.

Title: Assessment of proline contents in relation to stress conditions of certain pteridophytes of western ghats, South India

Subject: Indian Fern Journal
Keywords: Proline contents, stress condition, vegetative -fertile state, ferns, western ghats, South India
Abstract: Proline contents during stress and non-stress conditions have been studied in 18 species belonging to 15 genera of Pteridophytes from Western Ghats of South India. Assessment is made for both vegetative and fertile fronds. The accumulation of free proline is generally associated with the drought resistance capacity of a plant. Proline influences stress probably through its effect on the degradation of chlorophylls and accumulation of carotenoids in ferns. In most of the species studied presently, proline contents increase during fertile state of the plant.
