  • Liverworts, Mosses and Hornworts of Afghanistan - Our Present Knowledge
    ISSN 2336-3193 Acta Mus. Siles. Sci. Natur., 68: 11-24, 2019 DOI: 10.2478/cszma-2019-0002 Published: online 1 July 2019, print July 2019 Liverworts, mosses and hornworts of Afghanistan - our present knowledge Harald Kürschner & Wolfgang Frey Liverworts, mosses and hornworts of Afghanistan ‒ our present knowledge. – Acta Mus. Siles. Sci. Natur., 68: 11-24, 2019. Abstract: A new bryophyte checklist for Afghanistan is presented, including all published records since the beginning of collection activities in 1839 ‒1840 by W. Griffith till present. Considering several unidentified collections in various herbaria, 23 new records for Afghanistan together with the collection data can be added to the flora. Beside a new genus, Asterella , the new records include Amblystegium serpens var. serpens, Brachythecium erythrorrhizon, Bryum dichotomum, B. elwendicum, B. pallens, B. weigelii, Dichodontium palustre, Didymodon luridus, D. tectorum, Distichium inclinatum, Entosthodon muhlenbergii, Hygroamblystegium fluviatile subsp. fluviatile, Oncophorus virens, Orthotrichum rupestre var. sturmii, Pogonatum urnigerum, Pseudocrossidium revolutum, Pterygoneurum ovatum, Schistidium rivulare, Syntrichia handelii, Tortella inflexa, T. tortuosa, and Tortula muralis subsp. obtusifolia . Therewith the number of species increase to 24 liverworts, 246 mosses and one hornwort. In addition, a historical overview of the country's exploration and a full biogeography of Afghan bryophytes is given. Key words: Bryophytes, checklist, flora, phytodiversity. Introduction Recording, documentation, identification and classification of organisms is a primary tool and essential step in plant sciences and ecology to obtain detailed knowledge on the flora of a country. In many countries, such as Afghanistan, however, our knowledge on plant diversity, function, interactions of species and number of species in ecosystems is very limited and far from being complete.

  • Taxonomic Reevaluation of Didymodon Nigrescens (Pottiaceae) in Japan
    Hattoria 11: 61–75. 2020 Taxonomic reevaluation of Didymodon nigrescens (Pottiaceae) in Japan Yuya INOUE1, 2, Juan A. JIMÉNEZ3, Takumi SATO2, Hiromi TSUBOTA1 & Tomio YAMAGUCHI1 1 Program of Basic Biology, Graduate School of Integrated Sciences for Life, Hiroshima University, Kagamiyama 1–3–1, Higashihiroshima, Hiroshima 739–8526, Japan 2 Hattori Botanical Laboratory, Obi 6–1–26, Nichinan, Miyazaki 889–2535, Japan 3 Departamento de Biología Vegetal, Facultad de Biología, Universidad de Murcia, Campus de Espinardo 30100, Murcia, Spain Author for correspondence: Yuya INOUE, [email protected] Abstract Based on morphological investigation and molecular phylogenetic analysis, we find that the previous concept of Didymodon nigrescens (Mitt.) K.Saito sensu Saito in Japan includes D. nigrescens and D. subandreaeoides (Kindb.) R.H.Zander, the latter newly reported from Japan. Morphological and phylogenetic data from Japanese material clearly segregate these species from each other. In addition, Japanese D. nigrescens shows two groups, with morphological traits supporting the phylogeny, requiring further morpho-molecular evaluation based on broad sampling. Descriptions with analytical illustrations are provided based on Japanese material. Andreaea takakii Sakurai is proposed as a synonym of D. subandreaeoides. Introduction Didymodon nigrescens (Mitt.) K.Saito is a member of a group of Holarctic mosses whose range penetrates deeply into the tropics, including Central America and East Africa (Bednarek- Ochyra 2018). According to the monograph of Japanese Pottiaceae (Saito 1975), the species grows on calcareous rocks or cliffs in montane to subalpine zones, and was known from several localities from Central Honshu and Shikoku. Saito circumscribed the species by the following characters: (1) plants dark brown to blackish-green, (2) stems more or less branched, (3) basal cells of the leaves rhomboidal, sclerenchymatous near the costa, (4) seta moderately thick, strongly flattened when dry, and (5) perichaetial leaves about two times as long as the stem-leaves.

A note on Pottia intermedia (Turner) Fürnr. (Pottiaceae, Bryop- sida) with special reference to its phylogeny and new localities in SW Japan. Hikobia 16: 67–78. Eight new localities of Pottia intermedia (Turner) Fürnr. are recorded from Honshu and Shikoku (Hiroshima, Kagawa and Ehime Prefs.), SW Japan. Although it is widely distributed in the world, this species is a rare moss in Japan and is previously known from Honshu, Shikoku and Kyushu for Japan. Japanese populations of P. intermedia grow on soil in open sites, especially in citrus orchards. Analytical illustrations with SEM images of peristome, spores and leaf papillae and a discussion on the phyloge- netic position of this species are provided based on the materials collected.

  • Tortula Modica Pottia Intermedia Blunt-Fruited Pottia Key 266
    Pottiales Tortula modica Pottia intermedia Blunt-fruited Pottia Key 266 Capsules longer than wide 5 mm 1 mm 2 mm Identification This moss looks like T. truncata (p. 482), but with capsules longer than wide and leaves with partly recurved margins. Shoots form patches or occur scattered, up to 1.5 cm tall. Leaves are about 2–2.5 mm long. Capsules are common in winter and spring, longer (about 1–1.5 mm) than wide, and typically widest slightly below the rim. They are borne on a seta 4–6 mm long and have a pointed lid. The peristome is absent or rudimentary. Similar species T. truncata (p. 482) has capsules not (or very little) longer than wide and a distinctively wide mouth, and its leaves have plane margins. T. lanceola (p. 481) is a smaller moss (shoots up to 5 mm tall) and has dark, red-brown capsules that are more obviously narrowed at the rim and with an obvious peristome. T. viridifolia (p. 484) is typically smaller (shoots up to 5 mm tall), with leaves wider relative to their length, a less tapering tip, and often a more longly excurrent nerve. Pottiopsis caespitosa (p. 437) is a smaller moss (about 1 mm tall), with capsules hardly longer than wide. Pottia davalliana and P. starkeana (p. 487) are smaller mosses (shoots up to 3 mm tall), with leaves only about 1 mm long and capsules that have a bluntly conical rather than a longly pointed lid. Protobryum bryoides (p. 485) has a capsule that does not shed its lid, and usually shorter (2–5.5 mm long) setae, so that the capsules only just clear the leaves.

  • 2. Taxonomic Overview of the Plants of Singapore
    FLORA OF SINGAPORE (Vol. 1: 5–14, 2019) 2. TAXONOMIC OVERVIEW OF THE PLANTS OF SINGAPORE D.J. Middleton1, B.C. Ho1 & S. Lindsay2 The Flora of Singapore will be published in 14 volumes with the taxonomic accounts systematically arranged in volumes 2–14 and the introductory chapters in volume 1. The account of each family is pre-assigned to a volume and each volume will be printed when all of the content intended for the volume is ready. The taxonomic hierarchy used, the assignment of families to orders, and the order of presentation of families follows Frey & Stech (2009) for bryophytes, PPG I (2016) for lycophytes and ferns, Christenhusz et al. (2011) for gymnosperms, and APG IV (2016) for angiosperms, each modified with minor updates from more recent studies when appropriate. Traditionally, liverworts, mosses and hornworts were regarded as classes within a single plant division under Bryophyta sensu lato, i.e. Marchantiopsida/Hepaticae, Bryopsida/Musci and Anthocerotopsida/Anthocerotae, respectively. However, their interrelationships have long been a subject of debate and controversy among plant systematists (see review in Goffinet, 2000). Despite the availability of large genome-level studies from advances in sequencing technology, the phylogenetic relationships among the three bryophyte groups remain largely unresolved although there are two better-supported hypotheses (Cox, 2018). Nonetheless, the monophylies of each group are better established. As generally accepted today, the bryophytes for the Flora of Singapore will be treated as three separate divisions, namely Marchantiophyta, Bryophyta sensu stricto and Anthocerotophyta. The classifications within each of the three bryophyte divisions have undergone constant modification and adjustment, particularly in light of modern molecular phylogenetic systematics (Crandall-Stotler et al., 2009a,b; Goffinet et al., 2009; Renzaglia et al., 2009; Vilnet et al., 2009).

ИГНАТОВА1 Abstract Tortella densa (Lorentz & Molendo) Crundwell & Nyholm – a rare species with disjunctive Holarctic distribution is found in Russia for the first time in north-west- ern periphery of the Anabar Plateau (Taimyr District, East-Siberian Subarctic), ca. 3500 km from the nearest localities in North Europe and Alaska. This species dif- fers from the closely related T. inclinata (Hedw.) Limpr. by strongly and uniformly twisted leaves, and massive coroniform papillae on thickened outer cell walls in distal leaf lamina. The description and illustrations of Siberian specimen are given, and a comparison with European and American specimens are provided. Резюме Tortella densa (Lorentz & Molendo) Crundwell & Nyholm – редкий вид с преимущественно северным дизъюнктивным распространением в Европе и Северной Америке, впервые приводится для России с северо-западной периферии Анабарского плато (Таймырский Муниципальный р-н, восточно- сибирская Субарктика). Вид отличается от близкого T. inclinata (Hedw.) Limpr. однообразной сильной закрученностью листьев вокруг стебля, а также массивными коронообразными папиллами, сидящими на сильно утолщенных внешних стенках клеток дистальной части листа. Приводятся описание и иллюстрации сибирского образца и его сравнение с европейскими и американскими. Cибирское местонахождение вида удалено от ближайшего примерно на 3500 км. KEYWORDS: Tortella densa, Pottiaceae, Bryophyta, taxonomy, ecology, disjunc- tions, Siberia, Taimyr, Anabar Plateau The genus Tortella has never been specially of Anabar Plateau. Its position far from the Rus- revised in Russia. The checklist of East Europe sian borders is not the place where species not and North Asia (Ignatov et al., 2006) listed 8 spe- known from the country would be expected.

  • Tortula Muralis Wall Screw-Moss Key 121
    Pottiales Tortula muralis Wall Screw-moss Key 121 Spirally twisted peristome teeth 3 mm Twisted peristome 1 mm 3 mm 1 cm Long, silvery, excurrent nerve 5 mm Identification T. muralis is one of the first (and commonest) mosses that beginners will find. It grows in patches, tufts and neat cushions less than 1 cm tall. A long, smooth, silvery, excurrent nerve projects from the rounded leaf tip, making the moss look hoary grey when dry. The tongue-shaped leaf blade is 2–3.5 mm long, and twists and curls when dry, but the leaves spread away from each other when moist. The margins are recurved almost to the tip. The less common var. aestiva has a very short, excurrent green nerve. Narrowly cylindrical capsules develop from spring to autumn. They are held erect on a 1–2 cm long, purple seta, with a long peristome twisted into a spiral. Similar species Many Syntrichia species (pp. 494–501) also have tongue-shaped leaves with silvery, excurrent nerves, but are normally larger mosses (0.5 to several centimetres tall), with toothed or finely toothed, excurrent nerves.T. vahliana (Smith, p. 353) is rare on chalky soil, with a greenish excurrent nerve, and might be mistaken for T. muralis var. aestiva, but T. vahliana has leaves with plane margins or recurved only in mid-leaf. T. marginata (p. 477) might also be mistaken for T. muralis var. aestiva, but is usually smaller (2–3 mm tall), with no leaves longer than 2.5 mm, and has plane leaf margins with elongated cells that look pale when viewed through a hand lens.

  • A Taxonomic Study of Selected European Taxa of the Tortula Muralis (Pottiaceae, Musci) Complex: Variation in Morphology and Ploidy Level
    Preslia 81: 399–421, 2009 399 A taxonomic study of selected European taxa of the Tortula muralis (Pottiaceae, Musci) complex: variation in morphology and ploidy level Taxonomická studie vybraných evropských taxonů okruhu Tortula muralis (Pottiaceae, Musci): variabilita morfologických znaků a ploidní úrovně Jiří K o š n a r & Filip K o l á ř Department of Botany, Faculty of Science, University of South Bohemia, Branišovská 31, CZ-370 05, České Budějovice, Czech Republic; e-mail: [email protected] Košnar J. & Kolář F. (2009): A taxonomic study of selected European taxa of the Tortula muralis (Pottiaceae, Musci) complex: variation in morphology and ploidy level. – Preslia 81: 399–421. Four European taxa of the Tortula muralis complex (T. lingulata, T. muralis var. aestiva, T. muralis var. muralis, T. obtusifolia) were evaluated using multivariate analysis of morphological characters, a cultivation experiment and cytological screening (flow cytometry, chromosome counts). This study revealed that only T. lingulata is morphologically well defined within the complex and several new sporophytic characters that can be used to distinguish this taxon from the superficially most similar T. obtusifolia. The traditionally recognized taxa T. muralis var. muralis, T. muralis var. aestiva and T. obtusifolia showed continuous variation, with frequent intermediate plants. However, the main character of the gametophyte used for determination (costa excurrency) proved to be stable in cultivation, indicating that this character is under genetic control. Additionally, rather complex and only partly species-specific patterns of ploidy variation were found within the complex. Tortula lingulata and T. obtusifolia appear to be cytologically homogeneous; plants of T. lingulata were found to be diploid, whereas plants tentatively named as T.
