    African countries and neighbouring islands covered by the Synopsis. S T R E L I T Z I A 23 Synopsis of the Lycopodiophyta and Pteridophyta of Africa, Madagascar and neighbouring islands by J.P. Roux Pretoria 2009 S T R E L I T Z I A This series has replaced Memoirs of the Botanical Survey of South Africa and Annals of the Kirstenbosch Botanic Gardens which SANBI inherited from its predecessor organisations. The plant genus Strelitzia occurs naturally in the eastern parts of southern Africa. It comprises three arborescent species, known as wild bananas, and two acaulescent species, known as crane flowers or bird-of-paradise flowers. The logo of the South African National Biodiversity Institute is based on the striking inflorescence of Strelitzia reginae, a native of the Eastern Cape and KwaZulu-Natal that has become a garden favourite worldwide. It sym- bolises the commitment of the Institute to champion the exploration, conservation, sustain- able use, appreciation and enjoyment of South Africa’s exceptionally rich biodiversity for all people.

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.

  • (Polypodiales) Plastomes Reveals Two Hypervariable Regions Maria D
    Logacheva et al. BMC Plant Biology 2017, 17(Suppl 2):255 DOI 10.1186/s12870-017-1195-z RESEARCH Open Access Comparative analysis of inverted repeats of polypod fern (Polypodiales) plastomes reveals two hypervariable regions Maria D. Logacheva1, Anastasiya A. Krinitsina1, Maxim S. Belenikin1,2, Kamil Khafizov2,3, Evgenii A. Konorov1,4, Sergey V. Kuptsov1 and Anna S. Speranskaya1,3* From Belyaev Conference Novosibirsk, Russia. 07-10 August 2017 Abstract Background: Ferns are large and underexplored group of vascular plants (~ 11 thousands species). The genomic data available by now include low coverage nuclear genomes sequences and partial sequences of mitochondrial genomes for six species and several plastid genomes. Results: We characterized plastid genomes of three species of Dryopteris, which is one of the largest fern genera, using sequencing of chloroplast DNA enriched samples and performed comparative analysis with available plastomes of Polypodiales, the most species-rich group of ferns. We also sequenced the plastome of Adianthum hispidulum (Pteridaceae). Unexpectedly, we found high variability in the IR region, including duplication of rrn16 in D. blanfordii, complete loss of trnI-GAU in D. filix-mas, its pseudogenization due to the loss of an exon in D. blanfordii. Analysis of previously reported plastomes of Polypodiales demonstrated that Woodwardia unigemmata and Lepisorus clathratus have unusual insertions in the IR region. The sequence of these inserted regions has high similarity to several LSC fragments of ferns outside of Polypodiales and to spacer between tRNA-CGA and tRNA-TTT genes of mitochondrial genome of Asplenium nidus. We suggest that this reflects the ancient DNA transfer from mitochondrial to plastid genome occurred in a common ancestor of ferns.

The foliage of fern is highly valued in the international florist greenery market because of its long post-harvest life, low cost, year round availability and versatile design qualities in form, texture and colour. Ferns (Pteridophytes) are the seedless vascular plants, dominated the vegetation on earth about 280-230 million years ago. Although they are now largely replaced by the seed bearing vascular plants in the existing flora today, yet they constitute a fairly prominent part of the present day vegetation of the world. India with a highly variable climate has a rich diversity of its flora and Pteridophytic flora greatly contributes to its diversity. Pteridophytes also form an interesting and conscious part of our national flora with their distinctive ecological distributional pattern.

  • Epilist 1.0: a Global Checklist of Vascular Epiphytes
    Zurich Open Repository and Archive University of Zurich Main Library Strickhofstrasse 39 CH-8057 Zurich www.zora.uzh.ch Year: 2021 EpiList 1.0: a global checklist of vascular epiphytes Zotz, Gerhard ; Weigelt, Patrick ; Kessler, Michael ; Kreft, Holger ; Taylor, Amanda Abstract: Epiphytes make up roughly 10% of all vascular plant species globally and play important functional roles, especially in tropical forests. However, to date, there is no comprehensive list of vas- cular epiphyte species. Here, we present EpiList 1.0, the first global list of vascular epiphytes based on standardized definitions and taxonomy. We include obligate epiphytes, facultative epiphytes, and hemiepiphytes, as the latter share the vulnerable epiphytic stage as juveniles. Based on 978 references, the checklist includes >31,000 species of 79 plant families. Species names were standardized against World Flora Online for seed plants and against the World Ferns database for lycophytes and ferns. In cases of species missing from these databases, we used other databases (mostly World Checklist of Selected Plant Families). For all species, author names and IDs for World Flora Online entries are provided to facilitate the alignment with other plant databases, and to avoid ambiguities. EpiList 1.0 will be a rich source for synthetic studies in ecology, biogeography, and evolutionary biology as it offers, for the first time, a species‐level overview over all currently known vascular epiphytes. At the same time, the list represents work in progress: species descriptions of epiphytic taxa are ongoing and published life form information in floristic inventories and trait and distribution databases is often incomplete and sometimes evenwrong.

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’.

  • Major Evolutionary Events in the Origin and Diversification of the Fern Genus Polystichum (Dryopteridaceae)1
    American Journal of Botany 90(3): 508±514. 2003. MAJOR EVOLUTIONARY EVENTS IN THE ORIGIN AND DIVERSIFICATION OF THE FERN GENUS POLYSTICHUM (DRYOPTERIDACEAE)1 DAMON P. L ITTLE2 AND DAVID S. BARRINGTON3,4 2L. H. Bailey Hortorium, Cornell University, Ithaca, New York 14853-5908 USA; and 3Pringle Herbarium, Department of Botany and Agricultural Biochemistry, The University of Vermont, Burlington, Vermont 05405-0086 USA Recent advances in molecular systematics of the ferns make it possible to address long-standing questions about classi®cation of the major fern genera, such as the worldwide genus Polystichum (Dryopteridaceae), comprising at least 200 species. In this study we examined rbcL sequences and morphological characters from 55 fern taxa: 34 were from Polystichum and 21 were from other genera in the Dryopteridaceae. We found that Phanerophlebia, possibly including Polystichopsis, is the sister group to Polystichum sensu lato (s.l.), including Cyrtomium. Polystichum as commonly recognized is paraphyletic. Our results lead us to suggest recognizing the clade of earliest diverging Polystichum species as a distinct genus (Cyrtomidictyum) and to continue to recognize Cyrtomium as a separate genus, leaving a monophyletic Polystichum sensu stricto (s.s.). We resolved a tropical American clade and an African clade within Polystichum s.s. However, the resemblance between the once-pinnate, bulb-bearing calciphilic species found in Asia and the West Indies appears to be the result of convergent evolution. Optimizing our morphological character transformations onto the combined phylogeny suggests that the common ancestor of Polystichum s.l. and Phanerophlebia had evolved the common features of the alliance, including ciliate petiole-base scales, once-pinnate fronds, ultimate segments with scarious tips, peltate indusia, and microscales.
