The family is represented by 6-7 living genera and about 100-214 spp. in the world flora. With a view to bringing out an illustrated manual on the systematics of the family Marattiaceae in India, the three living genera Angiopteris 1 spp. (3 spp. according to Nishida, 1966), Marattia 1 sp., and Christerisenia 1 sp. occurring m India have been dealt with. It shows that while Angiopteris is distributed throughout India, Marattia and Christensenia are restricted to the Southern and the Eastern India, respectively.Full Text

The family Loxogrammaceae Ching ex Pic.-Ser. is represented by singular genus Loxogramme (Bl.) Presl. in India. Study and scrutiny of the herbarium specimens collected from all over India, and the specimens deposited at the Forest Research Institute, Dehra Dun (DD) and the National Botanical Research Institute, Lucknow (NBRI) together with the photographs of type and authentic specimens, microfisches, protologues etc. established the occurrence of 20 species against 2 species recognised by Beddome (1883, 1892) from the Indian-region. It has also been observed that morphologically two populations may be remarkably seggregated as larger fronds with monolete spores and smaller fronds with trilete spores. Three new taxa viz. L avalanchia Dixit et Das, L. mussooriana Dixit et Das and L. manipuriensis Das et Dixit have been described in addition to several new records of species reported by various workers from time to time.
Key to the species, illustrations of diagnostic characters, current nomenclature, description, specimens examined, distribution etc, have been provided for facilitating easy identification.

Central National Herbarium (CAL) is of immense value in assessing the biodiversity and status of occurrence of particular species in Indian region by virtue of possessing the treasure of herbarium specimens, since the last two centuries. About 195 genera of Pteridophytes are known to occur in India, of which only 20 genera are being represented by singular species or monotypie. The status of such genera in India has been assessed on the basis of specimens housed in CAL with probable conservation strategies to be adopted.Full Text

Wetlands are an important ecosystems in itself and also form an important life support systems for the flora and fauna. An extensive field survey and plant collection in Samaspur Bird Sanctuary (Salon Wetlands) situated in Rae Bareli district of Uttar Pradesk reveals that 192 species belonging to 147 genera and 59 families have been gathered from the area. Out of them 13 families 44 genera and 65 species are of monocots; 44 families, 101 genera and 125 species are of dicots and 2 families, 2 genera and 2 species are of pteridophytes. The systematic enumeration of plant species along with ecological notes, flowering and fruiting periods, and economic uses have been provided in each species. Besides, the floristic composition, the economic importance and conservation strategies have also been discussed.Full Text

Lindsaea bouillodii is a confused taxon as regards to its identity, nomenclature and distribution as given by various workers in the past. The report of its occurrence in Madras Presidency by Beddome (1865, 1883). has been substantiated by its recent collection from Tamil Nadu. It is attempted to clarify the matter by providing key to the taxa confused with it, detailed description and illustrations. Three new recrods of species i.e, L. glandulifera V.A.V.R. and L. malayensis Holtt, for India and L. chienii Ching for Burma are reported. Detailed descriptions and illustrations are provided to facilitate identification.Full Text
