Leaf Epidermal Morphology and Its Systematic Implications in Taiwan Pteridaceae
Taiwania, 48(1): 60-71, 2003 Leaf Epidermal Morphology and Its Systematic Implications in Taiwan Pteridaceae Yuan-Yuan Chuang(1) and Ho-Yih Liu(1, 2) (Manuscript received 16 October, 2002; accepted 10 March, 2003) ABSTRACT: Forty-nine species of Taiwan Pteridaceae were examined for their leaf epidermal features. Some of these features are stable characters without location variation, and are very good in differentiating taxa, especially at generic level. All genera except Cheilanthes were supported by the present study data. Taiwan Cheilanthes may be better divided into four genera. Leaf epidermal features are also provide some clues of systematic relationships among several genera. Coniogramme and Pteris may be more close to each other than previously thought. KEY WORDS: Taiwan, Pteridaceae, Leaf epidermal morphology, Scanning electron microscopy. INTRODUCTION As in many families of pteridophytes, the family Pteridaceae has been variously delimited. The most recent worldwide treatment (Tryon et al., 1990) included 6 subfamilies and 34 genera. The relationships among subfamilies, genera and infrageneric taxa were not clear in most cases (Tryon et al., 1990). The family number recognized for these plants in the past ranged from one to ten (Tryon et a1., 1990) might be related to these unclear relationships. In Taiwan, the classification of these plants was either one family system (Kuo, 1985, 1997) or three families, Adiantaceae, Parkeriaceae, and Pteridaceae (Huang et al., 1994). Chinese Flora (Ching and Shing, 1990) classified these Taiwan plants into six families: Acrostichaceae, Adiantaceae, Hemionitidaceae, Parkeriaceae, Pteridaceae, and Sinopteridaceae. Recently, studies using molecular (Gastony and Rollo, 1995, 1998; Hasebe et al., 1995; Wollenweber and Schneider, 2000) and micromorphological data (Chen and Huang, 1974; Lin and DeVol, 1977, 1978; Lee and Oh, 1988; Lee et al., 1990; Yu et al., 2001; Zhang and Li, 1999) have been attempted to give a better understanding of these plants. -

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.

Species Relationships and Farina Evolution in the Cheilanthoid Fern
Systematic Botany (2011), 36(3): pp. 554–564 © Copyright 2011 by the American Society of Plant Taxonomists DOI 10.1600/036364411X583547 Species Relationships and Farina Evolution in the Cheilanthoid Fern Genus Argyrochosma (Pteridaceae) Erin M.

A. 2 Missouri Botanical Garden, P.O. Box 299, St. Louis, Missouri 63166 U. S. A. 3 Author for correspondence ( [email protected] ) Communicating Editor: Lynn Bohs Abstract— Convergent evolution driven by adaptation to arid habitats has made it difficult to identify monophyletic taxa in the cheilanthoid ferns. Dependence on distinctive, but potentially homoplastic characters, to define major clades has resulted in a taxonomic conundrum: all of the largest cheilanthoid genera have been shown to be polyphyletic. Here we reconstruct the first comprehensive phylogeny of the strictly New World cheilanthoid genus Argyrochosma . We use our reconstruction to examine the evolution of farina (powdery leaf deposits), which has played a prominent role in the circumscription of cheilanthoid genera. Our data indicate that Argyrochosma comprises two major monophyletic groups: one exclusively non-farinose and the other primarily farinose. Within the latter group, there has been at least one evolutionary reversal (loss) of farina and the development of major chemical variants that characterize specific clades. Our phylogenetic hypothesis, in combination with spore data and chromosome counts, also provides a critical context for addressing the prevalence of polyploidy and apomixis within the genus. Evidence from these datasets provides testable hypotheses regarding reticulate evolution and suggests the presence of several previ- ously undetected taxa of Argyrochosma. -

Qk M. Chapman Vol. 30, pp. 179-184 December 1, 1917 PROCEEDINGS OF THE BIOLOGICAL SOCIETY OF WASHINGTON NOTES ON WESTERN SPECIES OF PELLAEA.* BY WILLIAM R. MAXON. The following notes relate chiefly to the taxonomy of the southwestern ferns for many years loosely associated under the name Pellaea Wrightiana Hook., to which Christensent has recently assigned the name Pellaea mucronata D. C. Eaton, in error. It is necessary to apply the name mucronata to a quite different plant, namely the California species long passing as P. ornithopus Hook., and to recognize three distinct species in the Pellaea Wrightiana of recent writers. The name mucronata, as applied to any species of the genus Pellaea, dates from 1856, with the publication of Allosorus mu- cronatus D. C. Eaton, based wholly on small specimens collected 'in the hills near the bay of San Francisco, California," by Major A. B. Eaton. This material, recently examined, clearly bears out Eaton's later statement! that his "original Allosorus mucronatus was founded on small specimens of P. ornithopus, of Hooker" (1858). In the Botany of the Mexican Boundary Survey (1859), however, Eaton had transferred A. mucronatus to Pellaea, making Pellaea mucronata include (in addition to P. ornithopus Hook.) the two southwestern forms described in 1858 as Pellaea Wrightiana Hook, and P. longimucronata Hook. Recognizing subsequently the error of associating the distinc- tively Californian plant with the new southwestern plants, and objecting (loc. cit.) to Baker's use of the name mucronata for the latter, Eaton yet failed to take up the name mucronata for the Californian plant, and on the contrary wrote Allosorus mucro- * Published with the permission of the Secretary of the Smithsonian Institution. -
1 Medicinal Plants of the Argentinean Puna
1 MEDICINAL PLANTS OF THE ARGENTINEAN PUNA: A COMMON PROPERTY RESOURCE AND AN OPPORTUNITY FOR LOCAL PEOPLE F.R. Barbarán1 Abstract Considering that poverty increased in Argentina due to local currency devaluation (400 %) in 2002, the objective of the project Cultivating the Health is to create certified phyto- medicines to give them for free to the rural poor. In order to contribute to that objective, I collected and identified the medicinal plants of the Argentinean Puna. The study area is placed in NW Argentina in Salta (Los Andes Department: 25636 Km2) and Jujuy Provinces (Susques Department: 9200 Km2), placed between 3500 and 5000 meters above sea level (m.a.s.l.), near the border with Bolivia and Chile. With the help of 3 medicine women and 18 local guides, 42 species of plants used as medicine by local people, were identified: 1 Pteridaceae, 1 Amaranthaceae, 1 Anacardiaceae, 2 Apiaceae, 13 Asteraceae, 2 Cactaceae, 2 Chenopodiaceae, 1 Ephedraceae, 2 Fabaceae, 1 Krameriaceae, 3 Lamiaceae, 2 Malvaceae, 1 Plantaginaceae, 3 Poaceae, 1 Rosaceae, 2 Solanaceae, 1 Tiphaceae and 4 Verbenaceae. According to their medicinal properties, 10 of those species are offered to tourists, despite one of them Werneria poposa (Asteraceae) is endangered. The traditional knowledge about the use of those plants is being eroded and lost, because now a day is easier for the dwellers to obtain medical attention in primary health care systems. On the other hand, the phytochemical and pharmacological properties of most of those species are little known. There is pharmaceutical information available for only 36 % of the species identified. -

Phytochrome Diversity in Green Plants and the Origin of Canonical Plant Phytochromes
ARTICLE Received 25 Feb 2015 | Accepted 19 Jun 2015 | Published 28 Jul 2015 DOI: 10.1038/ncomms8852 OPEN Phytochrome diversity in green plants and the origin of canonical plant phytochromes Fay-Wei Li1, Michael Melkonian2, Carl J. Rothfels3, Juan Carlos Villarreal4, Dennis W. Stevenson5, Sean W. Graham6, Gane Ka-Shu Wong7,8,9, Kathleen M. Pryer1 & Sarah Mathews10,w Phytochromes are red/far-red photoreceptors that play essential roles in diverse plant morphogenetic and physiological responses to light. Despite their functional significance, phytochrome diversity and evolution across photosynthetic eukaryotes remain poorly understood. Using newly available transcriptomic and genomic data we show that canonical plant phytochromes originated in a common ancestor of streptophytes (charophyte algae and land plants). Phytochromes in charophyte algae are structurally diverse, including canonical and non-canonical forms, whereas in land plants, phytochrome structure is highly conserved. Liverworts, hornworts and Selaginella apparently possess a single phytochrome, whereas independent gene duplications occurred within mosses, lycopods, ferns and seed plants, leading to diverse phytochrome families in these clades. Surprisingly, the phytochrome portions of algal and land plant neochromes, a chimera of phytochrome and phototropin, appear to share a common origin. Our results reveal novel phytochrome clades and establish the basis for understanding phytochrome functional evolution in land plants and their algal relatives. 1 Department of Biology, Duke University, Durham, North Carolina 27708, USA. 2 Botany Department, Cologne Biocenter, University of Cologne, 50674 Cologne, Germany. 3 University Herbarium and Department of Integrative Biology, University of California, Berkeley, California 94720, USA. 4 Royal Botanic Gardens Edinburgh, Edinburgh EH3 5LR, UK. 5 New York Botanical Garden, Bronx, New York 10458, USA. -
Cheilanthes (Cheilanthoideae, Pteridaceae), with Emphasis on South American Species
Organisms Diversity & Evolution (2018) 18:175–186 https://doi.org/10.1007/s13127-018-0366-6 ORIGINAL ARTICLE Further progress towards the delimitation of Cheilanthes (Cheilanthoideae, Pteridaceae), with emphasis on South American species M. Mónica Ponce1 & M. Amalia Scataglini1 Received: 20 July 2017 /Accepted: 22 April 2018 /Published online: 5 May 2018 # Gesellschaft für Biologische Systematik 2018 Abstract Cheilanthoid ferns (Cheilanthoideae sensu PPG 1 2016) constitute an important group within the Pteridaceae and are cosmopolitan in distribution. In South America, there are 155 species distributed in 13 genera, among which the largest are Adiantopsis (35), Cheilanthes (27), and Doryopteris (22). Most of the cheilanthoid species are morphologically adapted to grow in arid to semi-arid conditions and show convergent evolution, which has implied difficulties in defining the genera throughout their taxonomic history (Copeland 1947,Tryon&Tryon1973,Gastony&Rollo 1995, 1998,KirkpatrickSystematic Botany, 32:504–518, 2007, Rothfels et al. Taxon, 57: 712–724, 2008). Here, we sequenced two plastid markers (rbcL + trnL-F) of 33 South American cheilanthoid species, most of which have not been included in phylogenetic analyses previously. The South American species were analyzed together with South African and Australasian Cheilanthes and representatives of related cheilanthoid genera. The phylogenetic analysis showed that most Cheilanthes species are related to the genus Hemionitis, constituting different groups according to their distribu- tion; moreover, three species—C. hassleri, C. pantanalensis,andC. obducta—appear as the sister clade of Hemionitis. Cheilanthes micropteris, the type species, is strongly supported in a clade with Australasian Cheilanthes plus five South American Cheilanthes species, all of which show a reduction in the number of spores per sporangium; this feature would be a synapomorphy for core Cheilanthes s.s.
