A Revision of the Fern Genus Oleandra (Oleandraceae) in Asia 1 Doi: 10.3897/Phytokeys.11.2955 Monograph Launched to Accelerate Biodiversity Research

PhytoKeys 11: 1–37. doi: 10.3897/phytokeys.11.2955 Abstract The Asiatic species of Oleandra (Oleandraceae) are revised. We reduce a large number of species to O. neriiformis and O. sibbaldii, we provide a revised circumscription of O. cumingii and O. undulata and we establish the identity of O. vulpina. In total, we recognize 9 species, with full synonymy, descriptions and distribution maps. A list of identifications is appended. Keywords Oleandra, systematics Introduction Virtually all authors who have dealt with the genus Oleandra Cav. have commented on its distinctness or naturalness. The shrubby growth form, particularly distinct in O. neriiformis Cav., prompted Cavanilles (1799; 1802) not only to derive the genus name, but also the species name from Nerium oleander L. (Apocynaceae). From this it should be clear that he saw the aerial stems of Oleandra neriiformis, of which the forms with distinctly whorled fronds are indeed strongly reminiscent of branches of Nerium olean- der. -
A Taxonomic Revision of Hymenophyllaceae
BLUMEA 51: 221–280 Published on 27 July 2006 http://dx.doi.org/10.3767/000651906X622210 A TAXONOMIC REVISION OF HYMENOPHYLLACEAE ATSUSHI EBIHARA1, 2, JEAN-YVES DUBUISSON3, KUNIO IWATSUKI4, SABINE HENNEQUIN3 & MOTOMI ITO1 SUMMARY A new classification of Hymenophyllaceae, consisting of nine genera (Hymenophyllum, Didymoglos- sum, Crepidomanes, Polyphlebium, Vandenboschia, Abrodictyum, Trichomanes, Cephalomanes and Callistopteris) is proposed. Every genus, subgenus and section chiefly corresponds to the mono- phyletic group elucidated in molecular phylogenetic analyses based on chloroplast sequences. Brief descriptions and keys to the higher taxa are given, and their representative members are enumerated, including some new combinations. Key words: filmy ferns, Hymenophyllaceae, Hymenophyllum, Trichomanes. INTRODUCTION The Hymenophyllaceae, or ‘filmy ferns’, is the largest basal family of leptosporangiate ferns and comprises around 600 species (Iwatsuki, 1990). Members are easily distin- guished by their usually single-cell-thick laminae, and the monophyly of the family has not been questioned. The intrafamilial classification of the family, on the other hand, is highly controversial – several fundamentally different classifications are used by indi- vidual researchers and/or areas. Traditionally, only two genera – Hymenophyllum with bivalved involucres and Trichomanes with tubular involucres – have been recognized in this family. This scheme was expanded by Morton (1968) who hierarchically placed many subgenera, sections and subsections under -
Diversity of Pteridophytes in Western Ghats

Currently, there are 13,600 species of pteridophytes around the world, and is the second most dominant plant group. In India, there are 1200 pteridophyte species with 70 families and 192 genera. The pteridophyte hotspots in India are the Himalayas, Western Ghats, Eastern Ghats, Central India, and Andaman and the Nicobar Islands. The Western Ghats occupies only 6% of the Indian landmass and still holds a pteridophyte diversity of 383 species. Fern and fern allies are highly sensitive to changes in their natural habitat, thus habitat ABSTRACT destruction, anthropogenic influences, climate change, etc., are causing a fast decline in their population. Epiphytic species are easily destroyed due to the felling of trees and because of this at present 41- 43% of epiphytic pteridophytes in India are reported to be threatened. It necessitates the frequent analysis of the pteridophyte flora of a region to ensure the existence of its species diversity. The potential of in-vitro and ex-situ conservation techniques can be explored for the conservation of threatened pteridophyte species. -

Abstract The fern genus Tectaria has generally been placed in the family Tectariaceae or in subfamily Tectarioideae (placed in Dennstaedtiaceae, Dryopteridaceae or Polypodiaceae), both of which have been variously circumscribed in the past. Here we study for the first time the phylogenetic relationships of the associated genera Hypoderris (endemic to the Caribbean), Cionidium (endemic to New Caledonia) and Pseudotectaria (endemic to Madagascar and Comoros) using DNA sequence data. Based on a broad sampling of 72 species of eupolypods I (= Polypodiaceae sensu lato) and three plastid DNA regions (atpA, rbcL and the trnL-F intergenic spacer) we were able to place the three previously unsampled genera. -
Assessment of Diversity of Pteridophytes Along Some Hill Roads in a Biodiversity Hot Spot Region of India – a Case Study of Mizoram
ISSN: 2350-0328 International Journal of AdvancedResearch in Science, Engineering and Technology Vol. 5, Issue 9 , September 2018 Assessment of Diversity of Pteridophytes along Some Hill Roads in a Biodiversity Hot Spot Region of India – A Case Study of Mizoram Samar. Kr.Banerjee,MousumiBanerjee , Anjani.Kr. Srivastava Department of Botany, Ranchi University, Ranchi and Principal Consultant (Environment) STUP India1 Department of Botany,Faculty of Post Graduate Studies, Scottish Church College, Kolkata 2 Department of Botany, Ranchi University, Ranchi 3 ABSTRACT: Mizoram state of India isone of the biodiversity hotspots of the world, the Eastern Himalayan biodiversity hotspot of South Asia. Panoramic view of its roadside flora reveals that it is replete with rich diversity of Pteridophytes.This is due to unique location of Mizoram, its topography with hills and valleys, and also its geology which provide immense ranges of microclimatic conditions which facilitates its growth. These pteridophytes are one of the source of carbon sink along the road. Some work related to pteridophytes have been reported by some researchers in some protected areas like sanctuaries and some forests in Mizoram. Till date no work has been reported on the diversity, ecology and IUCN red list status of pteridophytes growing along the Hill Roads in Mizoram. The paper enlists he current diversity, habitat and ecology of such pteridophytes. Effort has been made to ascertain their status in the IUCN red list and in Catalogue of Life (COL).The study is likely to help in further capacity augmentation/widening of these roads without harming the current diversity of the pteridophytes growing there .The study also provides a protocol to be followedfor monitoring and management of biodiversity along other roads of this hotspot. -

Compared to seed plants, the diversity patterns of ferns have been poorly studied along disturbance gradients, including aspects of their taxonomic, phylogenetic, and functional diversity. Longnan County, a biodiversity hotspot in the subtropical zone in South China, was selected to obtain a more thorough picture of the fern–disturbance relationship, in particular, the taxonomic, phylogenetic, and functional diversity of ferns at different levels of disturbance. In 90 sample plots of 5 5 m2 along roadsides × at three sites, we recorded a total of 20 families, 50 genera, and 99 species of ferns, as well as 9759 individual ferns. The sample coverage curve indicated that the sampling effort was sufficient for biodiversity analysis. In general, the taxonomic, phylogenetic, and functional diversity measured by Hill numbers of order q = 0–3 indicated that the fern diversity in Longnan County was largely influenced by the level of human disturbance, which supports the ‘increasing disturbance hypothesis’. -
