Anomalies in Male Receptacles of Plagiochasma Appendiculatum Lehm
American International Journal of Available online at http://www.iasir.net Research in Formal, Applied & Natural Sciences ISSN (Print): 2328-3777, ISSN (Online): 2328-3785, ISSN (CD-ROM): 2328-3793 AIJRFANS is a refereed, indexed, peer-reviewed, multidisciplinary and open access journal published by International Association of Scientific Innovation and Research (IASIR), USA (An Association Unifying the Sciences, Engineering, and Applied Research) Anomalies in male receptacles of Plagiochasma appendiculatum Lehm. & Lindenb Pallvi Sharma and Anima Langer Department of Botany, University of Jammu, Jammu, Jammu and Kashmir-180006, INDIA Abstract: Plagiochasma appendiculatum Lehm. & Lindenb. belongs to the family Aytoniaceae which includes five genera (Plagiochasma, Reboulia, Asterella, Mannia and Cryptomitrium). Most of these genera show abnormalities in the development of reproductive structures. In the present paper, anomalies in the morphology and anatomy of male receptacles are reported in P.appendiculatum. Keywords: Plagiochasma appendiculatum; Aytoniaceae; Anomalies; Male receptacles I. Introduction Plagiochasma appendiculatum is a thalloid hepatic which is dorso-ventrally flattened. The male receptacles are normally horse-shoe shaped, sessile and present on the dorsal surface of the thallus, while the female ones are stalked, variously lobed (usually 3-5 lobed) and present on the main thallus too. Abnormality in their behaviour has been observed by bryologists like Kashyap and Bapna [1,4]. A second forking in the two lobes of androecium of P.appendiculatum is one of the important discovery (Kashyap, 1919). Abnormal female receptacles in the same genus were studied by Bapna and Bhagat [1,2] . Anomalies in the reproductive structures have also been studied in other members of family Aytoniaceae like unusual female receptacles in Asterella blumeana nees and Asterella khasiana [5] and abnormal male receptacles in Reboulia hemispherica [6]. -

Studies in the Marchantiales (Hepaticae) from Southern Africa. 6
Bothalia 24,2: 133-147 ( 1994) Studies in the Marchantiales (Hepaticae) from southern Africa. 6. The genus Asterella (Aytoniaceae: Reboulioideae) and its four local species S.M. PEROLD* Keywords: Asterella, A. bachmannii, A. marginata, A. muscicola, A. wilmsii, Aytoniaceae, Hepaticae, Marchantiales, Phragmoblepharis, Reboulioideae, section Saccatae, southern Africa ABSTRACT A taxonomic account of the genus Asterella, and four local representatives, A. muscicola, A. bachmannii, A. marginata and A. wilmsii, subgenus Phragmoblepharis, is given here. A key to the species is provided. Two specimens identified by Arnell ( ll)63) as Reboulia hemisphaerica, Collins 775 and Eyles CH 1175, are actually A. wilmsii', the presence of the genus Reboulia in southern Africa is therefore not confirmed and should be deleted from the annotated checklist by Magill & Schelpe (1979) and Plants of southern Africa: names and distribution (Arnold & De Wet 1993). UITTREKSEL n Taksonomiese verslag oor die genus Asterella, en vier van die plaaslike verteenwoordigers daarvan, A. muscicola, A. bachmannii, A. marginata cn A. wilmsii, subgenus Phragmoblepharis, word hier gegee. 'n Sleutel tot die spesies word verskaf. Twee eksemplare, Collins 775 en Eyles CH 1175, wat deur Amell (1963) as Reboulia hemisphaerica geidentifiseer is, is in werklikheid A. wilmsii', die teenwoordigheid van die genus Reboulia in Suider-Alrika is dus nie bevestig nie en dit behoort geskrap te word van die geannoteerde kontrolelys deur Magill & Schelpe (1979) en van Plants o f southern Africa: names and distribution (Arnold & EX* Wet 1993).

About the Book the Format Acknowledgments
About the Book For more than ten years I have been working on a book on bryophyte ecology and was joined by Heinjo During, who has been very helpful in critiquing multiple versions of the chapters. But as the book progressed, the field of bryophyte ecology progressed faster. No chapter ever seemed to stay finished, hence the decision to publish online. Furthermore, rather than being a textbook, it is evolving into an encyclopedia that would be at least three volumes. Having reached the age when I could retire whenever I wanted to, I no longer needed be so concerned with the publish or perish paradigm. In keeping with the sharing nature of bryologists, and the need to educate the non-bryologists about the nature and role of bryophytes in the ecosystem, it seemed my personal goals could best be accomplished by publishing online. This has several advantages for me. I can choose the format I want, I can include lots of color images, and I can post chapters or parts of chapters as I complete them and update later if I find it important. Throughout the book I have posed questions. I have even attempt to offer hypotheses for many of these. It is my hope that these questions and hypotheses will inspire students of all ages to attempt to answer these. Some are simple and could even be done by elementary school children. Others are suitable for undergraduate projects. And some will take lifelong work or a large team of researchers around the world. Have fun with them! The Format The decision to publish Bryophyte Ecology as an ebook occurred after I had a publisher, and I am sure I have not thought of all the complexities of publishing as I complete things, rather than in the order of the planned organization. -
Multi-Gene Phylogeny Supports Single Origin of Jungermannioid Perigynium
Ann. Bot. Fennici 44: 450–462 ISSN 0003-3847 (print) ISSN 1797-2442 (online) Helsinki 20 December 2007 © Finnish Zoological and Botanical Publishing Board 2007 Multi-gene phylogeny supports single origin of jungermannioid perigynium Xiaolan He-Nygrén Botanical Museum, Finnish Museum of Natural History, P.O. Box 7, FI-00014 University of Helsinki, Finland Received 23 Nov. 2006, revised version received 8 Feb. 2007, accepted 8 Feb. 2007 He-Nygrén, X. 2007: Multi-gene phylogeny supports single origin of jungermannioid perigynium. — Ann. Bot. Fennici 44: 450–462. Within the leafy liverworts, the evolution of the perigynium, the stem-derived struc- ture that protects the developing sporophytes, has been understood as merely a paral- lelism, and families that have this feature have been placed to various suborders. The present study suggests a single origin of the perigynium in the leafy liverworts and the presence of perigynium being a synapomorphy for the suborder Jungermanniineae. The phylogenetic analyses were conducted using thirty-four leafy liverworts including twelve genera bearing a perigynium, and sequence data for rbcL, rps4, trnL-F cpDNA and 26S nrDNA. Within the Jungermanniineae three monophyletic lineages are recog- nized: the Acrobolbaceae lineage, the Trichotemnomaceae–Balantiopsidaceae lineage, and the lineage consisting of Jungermanniaceae and its closest related Gymnomi- triaceae, Delavayellaceae, Geocalycaceae s. stricto, Antheliaceae, Calypogeiaceae and Gyrothyraceae. The long branches of the latter three families indicate that they are more isolated from a common jungermannioid ancestor. The family Jungermanniaceae is resolved as paraphyletic and its circumscription and relationships require further study.

On Syzygiella Nipponica (Adelanthaceae
Arctoa (2013) 22: 167-172 ON SYZYGIELLA NIPPONICA (ADELANTHACEAE, MARCHANTIOPHYTA) AND ITS FIRST RECORD IN RUSSIA О SYZYGIELLA NIPPONICA (ADELANTHACEAE, MARCHANTIOPHYTA) И ПЕРВОЙ НАХОДКЕ ЭТОГО ВИДА В РОССИИ ALEXEY D. POTEMKIN1 & YURIY S. MAMONTOV2,3 АЛЕКСЕЙ Д. ПОТЁМКИН1, ЮРИЙ С. МАМОНТОВ2,3 Abstract Syzygiella nipponica was collected in Primorye Territory on rocks. The plants were sterile and recognized due to prostrate shoots, coarsely papillose cell surface and sporadic postical intercalary branches not characteristic of known in Asia morphologically similar species of Jungermannia, Solenostoma, Plagiochila, Pedinophyllum, and Syzygiella. Collected plants are dissimilar to phyloge- netically allied Syzygiella autumnalis. Their generic position was identified in the basis of comparison of rbcL gene sequence. Joint morphological and molecular study of collected materials and morpho- logical tudy of collections from LE, KPABG, NICH, HIRO, HSNU, E (including types of Jamesoniella nipponica and its synonyms J. verrucosa, and J. perverrucosa) shows separate position of Syzygiella nipponica from S. autumnalis at the species level. Резюме Новый для России вид печёночников Syzygiella nipponica собран в Приморском крае на скалах. Растения стерильные и характеризуются стелющейся формой роста, грубопапиллозной по- верхностью клеток листьев, развитием ризоидов из брюшных оснований листьев и наличием вентрально-интеркалярного ветвления – сочетанием, которое не свойственно известным из Азии морфологически сходным видам родов Jungermannia, Solenostoma, Plagiochila, Pedinophyllum и Syzygiella. Собранные растения также не сходны с филогенетически близким видом S. autumna- lis, и их родовое положение было определено на основании сравнения нуклеотидных последо- вательностей по гену rbcL. Морфологическое и молекулярное исследование собранных мате- риалов, а также изучение морфологии образцов из LE, KPABG, NICH, HIRO, HSNU, E (включая тип вида Jamesoniella nipponica, а также типы синонимов этого вида – J. -

O. Box 299, St. Louis, MO 63166–0299 U.S.A.; [email protected] Abstract A widely accessible list of known plant species is a fundamental requirement for plant conservation and has vast applications. An index of published names of liverworts and hornworts between 2009 and 2010 is provided as part of a continued effort in working toward producing a world checklist of this group. Included in the list are also names overlooked by earlier indices. The list includes 30 higher taxa, 250 species, 52 infraspecific taxa, 31 autonyms, and two fossils for 2009 and 2010. A number of taxa not covered by the earlier indices for 2000-2008 are also included. Key words: Liverworts, hornworts, index, nomenclature Introduction Under the auspices of the Early Land Plants Today project, there has been a strong community-driven effort attempting to address the critical need to synthesize the vast nomenclatural, taxonomic and global distributional data for liverworts (Marchantiophyta) and hornworts (Anthocerotophyta) (von Konrat et al. 2010a). These endeavours are critical in providing the foundation to develop a working checklist of liverworts and hornworts worldwide; the first version is projected to be published in 2012. -

БОРОВИЧЕВ1,2, ВАДИМ А. БАКАЛИН3,4, АННА А. ВИЛЬНЕТ2 Abstract The genus Asterella P. Beauv. includes four species in Russia: A. leptophylla and A. cruciata are restricted to the southern flank of the Russian Far East and two others, A. saccata and A. lindenbergiana occur mostly in the subartcic zone of Asia and the northern part of European Russia. Asterella cruciata is recorded for the first time in Russia. The study of the ribosomal LSU (or 26S) gene and trnL-F cpDNA intron confirmed the placement of Asterella gracilis in the genus Mannia and revealed the close relationship of A. leptophylla and A. cruciata, and the rather unrelated position of A. saccata and A. lindenbergiana. The phylogenetic tree includes robustly supported terminal clades, however with only weak support for deeper nodes. In general, Asterella species and M. gracilis from Russia show low levels of infraspecific variation. An identification key and species descriptions based on Russian specimens are provided, along with details of specimens examined, ecology and diagnostic characters of species. Резюме Род Asterella P.
