The sporophyte of the Paleogene liverwort Frullania varians Caspary

We document the sporophyte of the extinct Frullania varians based on an inclusion in Late Oligocene Bitterfeld amber from Germany. The sporophyte consists of a short, ca. 45 µm thick seta that exceeds the perianth only slightly; the elongate-ovate, acute valves of the opened capsule are about 225 µm long, curved backwards and consist of an epidermal and an internal layer. Cell walls of both layers possess nodulose trigones. Several trumpet-shaped, unispiral elaters are fixed to the upper third of the internal valve layer. They have a length of ca. 150 µm and a diameter of 15–18 µm. A subglobose structure of 19 µm diameter is interpreted as a degraded spore. Fossil elaters and spores as well as capsule wall details of Frullaniaceae are described for the first time.doi:10.1002/mmng.20120000

People-Powered Research and Experiential Learning: Unravelling Hidden Biodiversity

Globally, thousands of institutions house nearly three billion scientific collections offering unparallelled resources that contribute to both science and society. For herbaria alone - facilities housing dried plant collections - there are over 3,000 herbaria worldwide with an estimated 350 million specimens that have been collected over the past four centuries. Digitisation has greatly enhanced the use of herbarium data in scientific research, impacting diverse research areas, including biodiversity informatics, global climate change, analyses using next-generation sequencing technologies and many others. Despite the entrance of herbaria into a new era with enhanced scientific, educational and societal relevance, museum specimens remain underused. Natural history museums can enhance learning and engagement in science, particularly for school-age and undergraduate students. Here, we outline a novel approach of a natural history museum using touchscreen technology that formed part of an interactive kiosk in a temporary museum exhibit on biological specimens. We provide some preliminary analysis investigating the efficacy of the tool, based on the Zooniverse platform, in an exhibit environment to engage patrons in the collection of biological data. We conclude there is great potential in using crowd‐sourced science, coupled with online technology to unlock data and information from digital images of natural history specimens themselves. Sixty percent of the records generated by community scientists (citizen scientists) were of high enough quality to be utilised by researchers. All age groups produced valid, high quality data that could be used by researchers, including children (10 and under), teens and adults. Significantly, the paper outlines the implementation of experiential learning through an undergraduate mathematics course that focuses on projects with actual data to gain a deep, practical knowledge of the subject, including observations, the collection of data, analysis and problem solving. We here promote an intergenerational model including children, high school students, undergraduate students, early career scientists and senior scientists, combining experiential learning, museum patrons, researchers and data derived from natural history collections. Natural history museums with their dual remit of education and collections-based research can play a significant role in the field of community engagement and people-powered research. There also remains much to investigate on the use of interactive displays to help learners interpret and appreciate authentic research. We conclude with a brief insight into the next phase of our ongoing people-powered research activities developed and designed by high school students using the Zooniverse platform

Notes on Early Land Plants Today 90. Some technical lectotypifications in liverworts (Marchantiophyta)

Twenty-two names of liverwort and hornwort taxa described from Central America are lectotypified. Most of the taxa have been identified as types earlier but not formally selected. Two taxa are supplementarily lectotypified as the original lectotypification could be applied on more than one specimen

Austral hepaticae 53. unraveling hidden diversity: a novel species of Frullania Raddi from New Zealand

Frullania crassissima J.J.Engel, von Konrat and Glenny, a member of the genus Frullania Raddi, is described and illustrated. It is morphologically most similar to F. setchellii, F. svihlana and F. falciloba, of New Zealand and F. vittiana of Lord Howe Island. The new species is also sister to F. squarrosula, F. nicholsonii, F. vittiana and F. falcilobaina previously published phylogenetic analysis. It shares with those species a falcate asymmetrical leaf lobule that is truncate at its apex. It differs from those species principally in the surface ornamentation of the perianth and leaf cell wall thickenings. It is currently only known from the type material, but is likely to be more widespread

El redescubrimiento de Frullania weberbaueri Steph., incluyendo su primer reporte para Chile, estado de conservación y lectotipificación

We report the finding of a population of Frullania weberbaueri in Parque Nacional Pan de Azúcar, Antofagasta Province, Chile. This taxon was previously known only from the type specimen collected by August Weberbauer in Lima in 1901. The new gathering is fertile so we describe here its sexuality and perianths, together with the oil bodies and the habitat used by the species, and we provide a map of its known distribution. A lectotype for the name is here designated. This is the first record of a liverwort for the deserts of northern Chile, and the southernmost record for Frullania sect. Meteoriopsis.Se reporta el hallazgo de una población de Frullania weberbaueri en el Parque Nacional Pan de Azúcar, Provincia de Antofagasta, Chile. Este taxón se conocía previamente sólo de la colección tipo realizada por August Weberbauer en Lima en 1901. La nueva colección está fértil, por lo que se describen aquí la sexualidad y los periantos, junto con los cuerpos oleosos y el hábitat utilizado por la especie, y se provee un mapa de su distribución conocida. Se designa un lectotipo para el nombre. Este es el primer registro de una hepática para los desiertos costeros del norte de Chile, y el registro más austral para Frullania sect. Meteoriopsis

Unlocking collections: New records of Lepidoziaceae (Marchantiophyta) for the islands of Fiji

It is clearly evident that the bryophyte flora of the islands of Fiji remains inadequately documented. Here, five liverwort species of Lepidoziaceae are reported as new to the Republic of Fiji: Lepidozia haskarliana, Neolepidozia cuneifolia, N. wallichiana, Telaranea major and Tricholepidozia melanesica

New records for the Falkland Islands moss flora

We present 25 new moss records for the Falkland Islands, together with vouchers for three names previously reported for the archipelago without specimen citation, based on recent collections made by the authors in several localities throughout the Falkland Archipelago. Voucher information together with habitat details are given for each of the taxa mentioned. With these new additions, the moss flora of the Falkland Islands rises to 185 taxa.</p
