Research Article PTERIDOPHYTE DIVERSITY IN WET EVERGREEN FORESTS OF SAKLESHPUR IN CENTRAL WESTERN GHATS Sumesh N. Dudani1, 2, M. K. Mahesh2, M. D. Subash Chandran1 and *T. V. Ramachandra1 1Energy and Wetlands Research Group, Centre for Ecological Sciences, Indian Institute of Science, Bangalore – 560 012 2Department of Botany, Yuvaraja’s College (Autonomous), University of Mysore, Mysore - 57005 ABSTRACT The present study deals with the diversity of pteridophytes in the wet evergreen forests of Sakleshpurtaluk of Hassan district in central Western Ghats. A significant portion of the study area comprises of the Gundia river catchment region which is considered to be the ‘hottest hotspot of biodiversity’ as it shelters numerous endemic and threatened species of flora and fauna. Survey of various macro and micro habitats was carried out in this region, also a haven for pteridophytes. A total of 45 species of pteridophytes from 19 families were recorded in the study. The presence of South Indian endemics like Cyathea nilgirensis, Bolbitissub crenatoides, B. semicordata and Osmunda huegeliana signifies the importance of this region as a crucial centre of pteridophytes. Similar regions in the Western Ghats, rich in network of perennial streams have been targeted widely for irrigation and power projects. With regard to an impending danger in the form a proposed hydro-electric project in the Gundia River, threatening the rich biodiversity, an overall ecological evaluation was carried out in the entire river basin.

Abstract The epiphytic fern genus Microgramma (Polypodiaceae) comprises 30 species occurring mainly in the Neotropics with one species in Africa, being an example of trans-Atlantic disjunction. Morphologically and ecologically, Microgramma presents a wide variation that is not seen in its closest related genera.

  • Fern Classification
    16 Fern classification ALAN R. SMITH, KATHLEEN M. PRYER, ERIC SCHUETTPELZ, PETRA KORALL, HARALD SCHNEIDER, AND PAUL G. WOLF 16.1 Introduction and historical summary / Over the past 70 years, many fern classifications, nearly all based on morphology, most explicitly or implicitly phylogenetic, have been proposed. The most complete and commonly used classifications, some intended primar• ily as herbarium (filing) schemes, are summarized in Table 16.1, and include: Christensen (1938), Copeland (1947), Holttum (1947, 1949), Nayar (1970), Bierhorst (1971), Crabbe et al. (1975), Pichi Sermolli (1977), Ching (1978), Tryon and Tryon (1982), Kramer (in Kubitzki, 1990), Hennipman (1996), and Stevenson and Loconte (1996). Other classifications or trees implying relationships, some with a regional focus, include Bower (1926), Ching (1940), Dickason (1946), Wagner (1969), Tagawa and Iwatsuki (1972), Holttum (1973), and Mickel (1974). Tryon (1952) and Pichi Sermolli (1973) reviewed and reproduced many of these and still earlier classifica• tions, and Pichi Sermolli (1970, 1981, 1982, 1986) also summarized information on family names of ferns. Smith (1996) provided a summary and discussion of recent classifications. With the advent of cladistic methods and molecular sequencing techniques, there has been an increased interest in classifications reflecting evolutionary relationships. Phylogenetic studies robustly support a basal dichotomy within vascular plants, separating the lycophytes (less than 1 % of extant vascular plants) from the euphyllophytes (Figure 16.l; Raubeson and Jansen, 1992, Kenrick and Crane, 1997; Pryer et al., 2001a, 2004a, 2004b; Qiu et al., 2006). Living euphyl• lophytes, in turn, comprise two major clades: spermatophytes (seed plants), which are in excess of 260 000 species (Thorne, 2002; Scotland and Wortley, Biology and Evolution of Ferns and Lycopliytes, ed.

  • <I>Cyclodium</I> (Dryopteridaceae)
    Plant Ecology and Evolution 152 (3): 521–530, 2019 https://doi.org/10.5091/plecevo.2019.1545 REGULAR PAPER Taxonomic novelties in Cyclodium (Dryopteridaceae) and a key to the species with free veins Amabily Bohn*, Fernando B. Matos & Paulo H. Labiak Universidade Federal do Paraná, Dept. de Botânica. Caixa Postal 19031, 81531-980, Curitiba, Paraná, Brazil *Corresponding author: [email protected] Background – Cyclodium is a neotropical fern genus comprising about ten species. Most species are found in northern South America, and the foothills of the Guiana Shield is an important region for species diversification. Our phylogenetic and taxonomic studies of the genus demonstrated the need to describe a new species and to recognize a variety at species level. Methods – This study is based on herbarium specimens from CAY, HUA, INPA, MBM, NY, P, RB, UC, UFP, UPCB, and US. Morphological characters were analyzed using standard procedures. The indumentum and spores of the new species were studied using a scanning electron microscope. Species delimitation is proposed based on our preliminary phylogenetic studies, as well as on morphology and geographical distribution. Key results – Cyclodium alansmithii Bohn & Labiak is recognized as a new species, described, and illustrated. The most similar species is Cyclodium inerme (Fée) A.R.Sm., from which it differs by ovate- lanceolate and bicolored scales, reduced fronds, truncate pinna bases, and non-ciliate indusia. Cyclodium alansmithii is currently assessed as Endangered (EN) using IUCN criteria, but more fieldwork and herbarium studies are necessary to establish a more accurate conservation assessment.

    Acta Botanica Brasilica 28(3): 404-407. 2014. doi: 10.1590/0102-33062014abb3389 Typification of some species names in Elaphoglossum section Polytrichia (Dryopteridaceae) from Brazil Fernando Bittencourt Matos1,3 Received: 16 October, 2013. Accepted: 18 March, 2014 ABSTRACT The fern genus Elaphoglossum has received a great deal of attention in Brazil over the last two centuries. Nevertheless, many of the early names remain inadequately typified. In this paper, the nomenclature of some Brazilian species of Elaphoglossum sect. Polytrichia is discussed under the rules and recommendations of the International Code of No- menclature for algae, fungi, and plants. Lectotypes are designated for the following names: Acrostichum amplissimum Fée; A. apodum Kaulf. var. sprucei Baker; A. glaziovii Fée; A. lindbergii Mett. ex Kuhn; A. prestonii Baker; Elaphoglossum spannagelii Rosenst.; and Elaphoglossum ulei H. Christ. Most of these types were collected in Brazil during the 19th century and are now preserved in several European herbaria. Key words: Ferns, neotropics, nomenclature, taxonomy, types Introduction Brazil. The members of this section can be recognized mor- phologically by the presence of subulate scales and absence During the preparation of a taxonomic revision of Ela- of hydathodes on the leaves of adult sporophytes (Mickel phoglossum Schott ex J. Sm. (Dryopteridaceae) in Brazil, I & Atehortúa 1980; Matos & Moran 2013). found several scientific names that needed to be lectotypi- fied. Many of these names were first published in Acrosti- chum L., which formerly included all ferns with acrostichoid Material and methods sori. It is realized nowadays that such an assemblage results in a paraphyletic group containing species now placed in This study was largely based on the examination of distinct families (see Smith et al.
