Genetic Differentiation and Polyploid Formation Within the Cryptogramma Crispa Complex (Polypodiales: Pteridaceae)
Turkish Journal of Botany Turk J Bot (2016) 40: 231-240 http://journals.tubitak.gov.tr/botany/ © TÜBİTAK Research Article doi:10.3906/bot-1501-54 Genetic differentiation and polyploid formation within the Cryptogramma crispa complex (Polypodiales: Pteridaceae) Jordan METZGAR*, Mackenzie STAMEY, Stefanie ICKERT-BOND Herbarium (ALA), University of Alaska Museum of the North and Department of Biology and Wildlife, University of Alaska Fairbanks, Fairbanks, AK, USA Received: 28.01.2015 Accepted/Published Online: 14.07.2015 Final Version: 08.04.2016 Abstract: The tetraploid fern Cryptogramma crispa (L.) R.Br. ex Hook. is distributed across alpine and high latitude regions of Europe and western Asia and is sympatric with the recently described octoploid C. bithynica S.Jess., L.Lehm. & Bujnoch in north-central Turkey. Our analysis of a 6-region plastid DNA sequence dataset comprising 39 accessions of Cryptogramma R.Br., including 14 accessions of C. crispa and one accession of C. bithynica, revealed a deep genetic division between the accessions of C. crispa from western, northern, and central Europe and the accessions of C. crispa and C. bithynica from Turkey and the Caucasus Mountains. This legacy likely results from Pleistocene climate fluctuations and appears to represent incipient speciation between the eastern and western clades. These plastid DNA sequence data also demonstrate that the western clade of C. crispa, specifically the western Asian clade, is the maternal progenitor of C. bithynica. Our analysis of DNA sequence data from the biparentally inherited nuclear locus gapCp supports an autopolyploid origin of C. bithynica, with C. crispa as the sole progenitor.

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. -
Morphological and Anatomical Adaptations to Dry, Shady Environments in Adiantum Reniforme Var
Morphological and anatomical adaptations to dry, shady environments in Adiantum reniforme var. sinense (Pteridaceae) Di Wu1, Linbao Li1, Xiaobo Ma1, Guiyun Huang1 and Chaodong Yang2 1 Rare Plants Research Institute of Yangtze River, Three Gorges Corporation, Yichang, China 2 Engineering Research Center of Ecology and Agriculture Use of Wetland, Ministry of Education, Yangtze University, Jingzhou, China ABSTRACT The natural distribution of the rare perennial fern Adiantum reniforme var. sinense (Pteridaceae), which is endemic to shady cliff environments, is limited to small areas of Wanzhou County, Chongqing, China. In this study, we used brightfield and epifluorescence microscopy to investigate the anatomical structures and histochemical features that may allow this species to thrive in shady, dry cliff environments. The A. reniforme var. sinense sporophyte had a primary structure and a dictyostele. The plants of this species had an endodermis, sclerenchyma layers and hypodermal sterome, reflecting an adaption to dry cliff environments. Blades had a thin cuticle and isolateral mesophyll, suggesting a tolerance of shady environments. These characteristics are similar to many sciophyte ferns such as Lygodium japonicum and Pteris multifida. Thus, the morphological and anatomical characteristics of A. reniforme var. sinense identified in this study are consistent with adaptations to shady, dry cliff environments.

Endrés As an Illustrator
chapter∑ 4 Endrés as an illustrator Franco Pupulin According to the definition provided by Botanical Gardens Conservation International, “the main goal of botanical illustration is not art, but scientific accuracy”. A botanical illustrator must portray a plant with enough precision and detail for it to be recognized and distinguished from another species, and the need for exactness is what fundamentally differentiates botanical illustration from more general flower painting. If, traditionally, the best botanical illustrators try to understand the structure of plants and to communicate that in an aesthetically pleasing manner, combining science and art, this was probably not the concern of Auguste R. Endrés when preparing his orchid illustrations in Costa Rica. He had, however, a remarkable artistic talent, and his activity was influenced by the great tradition of orchid painting. The results of his illustration work not only attain the highest levels of botanical accuracy, but set a new standard in orchid art and science. As we will see, only because his masterful plates were lost among the forgotten materials of Reichenbach’s venomous legacy, was Endrés’ work prevented from having a major influence on the discipline of botanical illustration. The golden age of botanical illustration in Europe Beginning in the 17th century, and more frequently during the Enlightenment of the 18th Century, European artists and scientists undertook major projects for collecting and cataloguing nature in its amazing variety. 1613 saw the publication of the Hortus Eystettensis1 (literally the Garden of Eichstätt), a landmark work in the history of botanical art and one of the greatest botanical sets ever created. -
Global Affinities: the Natural Method and Anomalous Plants in the Nineteenth Century Lorelai Kury
HoST - Journal of History of Science and Technology Vol. 15, no. 1, June 2021, pp. 39-70 10.2478/host-2021-0003 SPECIAL ISSUE GLOBAL FLORA: MASTERING EXOTIC PLANTS (EIGHTEENTH—NINETEENTH CENTURIES) Global Affinities: The Natural Method and Anomalous Plants in the Nineteenth Century Lorelai Kury Casa de Oswaldo Cruz, Fiocruz, Brazil [email protected] Sara Albuquerque IHC-Nova FCSH, Pólo Universidade de Évora, Portugal [email protected] Abstract: Approaching from an analysis of the work of Robert Brown (1773-1858) and Friedrich Welwitsch (1806-1872) on Rafflesiaand Welwitschia, this article explores how the “natural method” became a tool for understanding extra-European flora in the nineteenth century. As botanists worked to detect “hidden affinities” between plants that would enable them to identify the so-called natural families to which even anomalous species belonged, they relied on comparison as their basic methodological procedure, making it essential for them to have access to collections. In their scientific writings, professional botanists tended to steer clear of any emphasis on plant exoticism. While botany engaged in dialogue with various types of approaches, the field essentially normalized the exotic. The article’s exploration of the hermetic style of scientific texts and the way botanists incorporated illustrators’ work sheds light on the complexity of the spaces where natural history was done, in a context where plants were circulating from around the globe.

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’. -

Cuba Center, and Pennsylvania Horticultural Society. Under David’s stellar leadership, we partnered with WiLS (Wisconsin Library Services), a member-driven non-profit that provides services to library organizations and their partners. The very capable WiLS staff worked with us to find a suitable eBook vendor. This was not easy; most vendors deal with large public or university libraries and offer access to eBooks as large collections consisting of a range of topics. We, however, represented a relatively small user base with specialized interests: horticulture and botany, with tangential needs in other areas covered in our collections. We had our first conference call in October 2012. We spent a year and a half setting up the consortium, finding a vendor and implementing the new platform. By the summer of 2014 we were in business – we had the ability to search, find, read, and download horticultural and botanical eBooks on the eBrary platform. Over the years, more libraries joined the consortium: the Los Angeles County Arboretum and Botanic Garden (Susan Eubank); the Morton Arboretum in Lisle, Illinois (Rita Hassert); and the Denver Botanic Gardens (Allaina Wallace). -
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. -

Sir Joseph Hooker's Collections at the Royal
Fig. 1. Portrait of Sir Joseph Hooker in his study, pencil drawing by Theodore Blake Wirgman, 1886 (Kew Art Collection). SIR JOSEPH HOOKER’S COLLECTIONS AT THE ROYAL BOTANIC GARDENS, KEW David Goyder, Pat Griggs, Mark Nesbitt, Lynn Parker and Kiri Ross-Jones Introduction On the December 9, 2011, just one day short of the centenary of the death of Sir Joseph Dalton Hooker, his life and work were celebrated by over 150 participants at a conference at the Royal Botanic Gardens, Kew. The afternoon session consisted of displays of Sir Joseph’s collections in the Herbarium building, ranging from herbarium specimens and economic botany to art, archives and books. This paper attempts to capture the experience in a more permanent form, highlighting the quantity and quality of collections accumulated during Sir Joseph’s career, both in his official role as Curtis’s Botanical Magazine 2012 vol. 29 (1): pp. 66–85 66 © The Board of Trustees of the Royal Botanic Gardens, Kew 2012. Director of Kew, and as an avid collector and scientist from childhood to his death. We aim to demonstrate that these collections are larger and more intact than is usually appreciated, and that they form a rich resource for scientific and historical research. Current work at Kew on cataloguing and digitisation is making many of these collections increasingly accessible. Any one strand of work in Joseph Hooker’s long life, from 1817 to 1911, would have been a remarkable achievement (Endersby, 2004; Griggs, 2011). His travels and collecting in Antarctica and the South Pacific, Sikkim and Nepal, the Near East, Morocco and the western United States led to the discovery of many new species, and important introductions of garden plants to Europe (Desmond, 1999). -

Carl J. Rothfels and Michael A. Sundue contributed equally to this work. Author for correspondence: Carl J. Rothfels, [email protected] Abstract We present a family-level classification for the eupolypod II clade of leptosporangiate ferns, one of the two major lineages within the Eupolypods, and one of the few parts of the fern tree of life where family-level relationships were not well understood at the time of publication of the 2006 fern classification by Smith & al. Comprising over 2500 species, the composition and particularly the relationships among the major clades of this group have historically been contentious and defied phylogenetic resolution until very recently. Our classification reflects the most current available data, largely derived from published molecular phylogenetic studies.
