“…Investigations of the present author, however, demonstrated that the Walchia-like remains could well be ascribed to Ortiseia Florin, a Late Permian representative of the Walchiaceae (Clement-Westerhof, 1984); moreover, vegetative remains and prepollen assignable to this family have been mentioned from outer Alpine Late Permian deposits.…”

“…The interpretation of Clement-Westerhof (1984) that "Walchiostrobus" dwarf-shoots do not exhibit "stalked" ovules, but bear their ovules abaxially on fertile scales has been independently confirmed by observations of Meyen (1984). The suggestion that these dwarfshoots could represent an ancestral form would imply the assumption of a radial arrangement of fertile and sterile scales.…”

“…The material studied originates from the Dolomites (localities Butterloch and Taubenleck in the Bletterbach area) and the Vicentinian Alps (localities Scocchi, Ulbe and Casarotti). For a detailed survey on the Val Gardena Formation and the localities one is referred to Clement-Westerhof (1984).…”

“…In this respect only genera from which both the ovuliferous fructifications and the epidermal structure are known, can be taken into consideration. These include the Late Permian genera Ortiseia Florin 1964(Clement-Westerhof, 1984, Pseudovoltzia Florin 1927(Schweitzer, 1962, 1963 and Ullmannia G6ppert 1850 (Florin, 1944;Schweitzer, 1962Schweitzer, , 1963Ullrich, 1964). Also vegetative remains, assignable to U. bronnii, collected from Frankenberg W. Germany, locus typicus of this species, is taken into consideration, (see Plate X, 5-6; Plate XI, 1).…”

II Abstract Clement-Westerhof, J.A., 1987A new family--the Majonicaceae--is proposed to include the genera Majonica, Dolomitia and Pseudovoltzia. The family is characterized by a peculiar organization of the ovuliferous dwarf-shoots, i.e. the places of ovule-attachment on the lateral fertile scales varying from explicitly laterally situated to more or less shifted to the adaxial side of the dwarf-shoot. RiassuntoIn base al materiale ricco vegetativo e fertile proviente dalle Formazione di Val Gardena nelle Dolomiti ed Alpi Vicentine, reste delle conifere sono state studiate in detaglio con l'aiuto dell'analisi di cuticola.Oltre il genere Ortiseia, tre altri generi naturali si puo distinguere: Majonica nov. gen., Dolomitia nov. gen. and Pseudovoltzia Florin. Ambie due Majonica and Dolomitia ~ riconnosciuto un solo species, Majonica alpina nov. sp. e Dolomitia cittertiae nov. sp. respettivamente. In Pseudovoltzia si possono distinguere due specie distinte: P. liebeana (Geinitz) Florin e P. sjerpii nov. sp.I1 genere Majonica, Dolomitia e Pseudovoltzia si sono associati con coni ovuliferi e Majonica perfino con cone pollinici e grani di pollini bisaccate e bitaeniati.Una famiglia nuova--le Majonicaceae---~ proposta in modo da includere i generi Majonica, Dolomitia e Pseudovoltzia.La famiglia sono caratterizzati per un' organizzazione particulare dei rami nani ovuliferi, i attaccamenti dei ovuli su foglie fertili laterali variata dalla posizione lateralemente evidente fino la posizione pifi meno rimossa dal posto adassiale del ramo nano.

“…This plant material includes well-preserved, decimetrelong foliage, shoots, stem fragments, fructifications, cuticle sheets and dispersed seeds. The plant taxa consist of ginkgophytes (50%: Baiera Braun, 1843, Sphenobaiera Florin, 1936), conifers (40%: Ortiseia Florin, 1964, Quadrocladus Schweitzer, 1960, Pseudovoltzia Florin, 1927, Dolomitia Clement-Westerhof, 1987, taeniopterids (2%: Taeniopteris Brongniart, 1828), seed ferns (1%: Germaropteris Kustatscher et al, 2014, Sphenopteris (Brongniart) Sternberg, 1825), and sphenophytes (< 1%) (Clement-Westerhof, 1984, 1987Poort and Kerp, 1990;Visscher et al, 2001;Bauer et al, 2014;Kustatscher et al, 2012Kustatscher et al, , 2014Kustatscher et al, , 2017.

Keywords:Tetrapoda flora phytoprovinces plant-insect interactions climate endemism latitudinal diversity gradient A B S T R A C TThe late Palaeozoic is a pivotal period for the evolution of terrestrial ecosystems. Generalised warming and aridification trends resulted in profound floral and faunal turnover as well as increased levels of endemism. The patchiness of well-preserved, late Permian terrestrial ecosystems, however, complicates attempts to reconstruct a coherent, global scenario. In this paper, we provide a new reconstruction of the Bletterbach Biota (Southern Alps, NE Italy), which constitutes a unique, low-latitude record of Lopingian life on land. We also integrate floral, faunal (from skeletal and footprint studies), and plant-insect interaction data, as well as global climatic interpretations, to compare the composition of the 14 best-known late Permian ecosystems. The results of this ecosystem-scale analysis provide evidence for a strong correlation between the distribution of the principal clades of tetrapod herbivores (dicynodonts, pareiasaurs, captorhinids), phytoprovinces and climatic latitudinal zonation. We show that terrestrial ecosystems were structured and provincialised at high taxonomic levels by climate regions, and that latitudinal distribution is a key predictor of ecosystem compositional affinity. A latitudinal diversity gradient characterised by decreasing richness towards higher latitudes is apparent: mid-to lowlatitude ecosystems had the greatest amount of high-level taxonomic diversity, whereas those from high latitudes were dominated by small numbers of higher taxa. The high diversities of tropical ecosystems stem from their inclusion of a mixture of late-occurring holdovers from the early Permian, early members of clades that come to prominence in the Triassic, and contemporary taxa that are also represented in higher latitude assemblages. A variety of evidence suggests that the Permian tropics acted as both a cradle (an area with high origination rates) and museum (an area with low extinction rates) for biodiversity.

Aus dem Unterrotliegend bei Alsenz, Saar-Nahe-Becken, (Clan-Cruppe, Lauterecken-Odernheim-Schichten, basale L-0 6) wird eine meso-bis xerophile Flora beschrieben und abgebildet. Die Flora wird von Coniferen dominiert. Die hiiutigsten Coniferen sind Hermitia sp. A, Hermitia grrmanica (FLORIN) Zwei radiiirsymmetrische Fruktitikationen der Gattung Peltuspermum belegen, dass die Diversifikation der Peltaspermen wesentlich friiher als bislang angenommen, namlich bereits im oberen Karbon, stattgefunden hatte. Die Flora wird mit anderen Hinterlandfloren des Saar-Nahe-Beckens aus Oberhausen an der Appel (Unterrotliegend) und Fisch-bachMiederworresbach (unterstes Oberrotliegend) verglichen und palaoijkologisch interpretiert.
