  • 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.

Forehand, Ph.D., Dean of the Graduate College ABSTRACT Together with the heterosporous lycophytes, the clubmoss family (Lycopodiaceae) is the sister lineage to all other vascular land plants. Given the family’s important position in the land-plant phylogeny, studying the evolutionary history of this group is an important step towards a better understanding of plant evolution. Despite this, little is known about the Lycopodiaceae, and a well-sampled, robust phylogeny of the group is lacking.

A comparative study of spores of seven species: Taenitis blechnoides (Willd.) Sw., T. hookeri (C. Chr.) Holttum, T. pinnata (J. Sm.) Holttum, Syngramma alismifolia (Presl) J. Sm., S. lobbiana (Hook.) J. Sm., S. quinata (Hook.) Carruth., and Austrogramme boerlageana (Alderw.) Hennipman from South-Eastern Asia was performed us- ing the method of scanning electronic microscopy (SEM). Spores of all examined species are trilete, tetrahedral or tet- rahedral-globose. Spores of Syngramma and Austrogramme are very similar to each other in shape and ornamentation. Ornamentation of both sides of spore is similar, verrucate (microverrucate), surface covered by rodlets and granulate deposits. Spores of Taenitis species with conspicuous cingulum (Taenitis blechnoides) or without it, ornamentation of both faces of spore could be tuberculate or baculate. Spores of Taenitis hookeri and Taenitis pinnata demonstrate tendency to forming of comissural ridges. Spore size of all studied species is close: equatorial diameter of spores of Taenitis species varies within 24–43 μm, those for Syngramma species is 29.8–35.5 μm, spores of Austrogramme boerlageana are smallest, their equatorial diameter varies within 22.5–29.4 μm.

Generic circumscriptions within the vittarioid clade were among the first in ferns to be evaluated and revised based on molecular phylogenetic data. Initial analyses of rbcL sequences revealed strong geographic structure and demonstrated that the two largest vittarioid genera, as then defined, each had phylogenetically distinct American and Old World components. The results of subsequent studies that included as many as 36 individuals of 33 species, but still relied on a single gene, were generally consistent with the early findings.

We present a revised classification for extant ferns, with emphasis on ordinal and familial ranks, and a synop- sis of included genera. Our classification reflects recently published phylogenetic hypotheses based on both morphological and molecular data. Within our new classification, we recognize four monophyletic classes, 11 monophyletic orders, and 37 families, 32 of which are strongly supported as monophyletic. One new family, Cibotiaceae Korall, is described. The phylogenetic affinities of a few genera in the order Polypodiales are unclear and their familial placements are therefore tentative. Alphabetical lists of accepted genera (including common synonyms), families, orders, and taxa of higher rank are provided. KEYWORDS: classification, Cibotiaceae, ferns, monilophytes, monophyletic. INTRODUCTION Euphyllophytes Recent phylogenetic studies have revealed a basal dichotomy within vascular plants, separating the lyco- Lycophytes Spermatophytes Monilophytes phytes (less than 1% of extant vascular plants) from the euphyllophytes (Fig.

  • Evodevo: Past and Future of Continuum and Process Plant Morphology
    philosophies Review EvoDevo: Past and Future of Continuum and Process Plant Morphology Rolf Rutishauser Department of Systematic and Evolutionary Botany, University of Zurich, CH-8008 Zurich, Switzerland; [email protected] Received: 7 October 2020; Accepted: 26 November 2020; Published: 1 December 2020 Abstract: Plants and animals are both important for studies in evolutionary developmental biology (EvoDevo). Plant morphology as a valuable discipline of EvoDevo is set for a paradigm shift. Process thinking and the continuum approach in plant morphology allow us to perceive and interpret growing plants as combinations of developmental processes rather than as assemblages of structural units (“organs”) such as roots, stems, leaves, and flowers. These dynamic philosophical perspectives were already favored by botanists and philosophers such as Agnes Arber (1879–1960) and Rolf Sattler (*1936). The acceptance of growing plants as dynamic continua inspires EvoDevo scientists such as developmental geneticists and evolutionary biologists to move towards a more holistic understanding of plants in time and space. This review will appeal to many young scientists in the plant development research fields. It covers a wide range of relevant publications from the past to present. Keywords: process philosophy; scientific perspectivism; developmental genetics; plant structure ontology; homology; land plant phylogeny; morphological misfits; flower; phyllotaxis; Utricularia 1. Introduction Plant morphology is the study of the physical form and structure of plants. Literally, the term “morphology” is derived from the Greek roots: morphe, which means form and/or structure, and logos, meaning discourse or investigation [1]. Plant morphology usually includes plant anatomy, which is the study of the internal structure of plants, as seen at the microscopic level.
