The breakup history of Gondwana and its impact on pre-Cenozoic floristic provincialism
The broad succession of pre-angiosperm floras is documents, the distinctive elements of the Early Cretaceous Gondwanan floras immediately preceding the appearance of angiosperms are highlighted and it is suggested that latitudinal controls strongly influenced the composition of GONDwananFloras through time even in the absence of marine barriers between Gondwana and the northern continents.

Gondwanan floristic and sedimentological trends during the Permian–Triassic transition: new evidence from the Amery Group, northern Prince Charles Mountains, East Antarctica
The Permian-Triassic boundary within the Amery Group of the Lambert Graben is placed at the contact between the Bainmedart Coal Measures and overlying Flagstone Bench Formation, based on the firstExpand
Some Morphological Features of Wollemi Pine (Wollemia nobilis: Araucariaceae) and Their Comparison to Cretaceous Plant Fossils
Reexamination of Mesozoic and Tertiary paleofloras will most probably reveal an important contribution of Wollemia to the fossil record of Araucariaceae. Expand
Nothofagus Biogeography Revisited with Special Emphasis on the Enigmatic Distribution of Subgenus Brassospora in New Caledonia
Considering all parameters, the occurrence of Brassospora in New Caledonia is most parsimoniously explained as a single colonization event from New Zealand where the subgenus subsequently went extinct in the Pliocene. Expand
Parallel evolution of angiosperm colour signals: common evolutionary pressures linked to hymenopteran vision
The degree of variability in flower coloration for particular angiosperm species matched the range of reflectance colours that can only be discriminated by bees that have experienced differential conditioning, suggesting a requirement for plasticity in the nervous systems of pollinators to allow generalization of flowers of the same species while overcoming the possible presence of non-rewarding flower mimics.

Synchronous palynofloristic extinction and recovery after the end-Permian event in the Prince Charles Mountains, Antarctica: Implications for palynofloristic turnover across Gondwana
In the Prince Charles Mountains (PCMs) the conformable Permian-Triassic (P-T) succession is characterised by an abrupt transition from coal-bearing to coal-lacking strata, which coincides with theExpand
Patterns of Gondwana plant colonisation anddiversification
Abstract Charting the broad patterns of vascular plant evolution for Gondwana againstthe major global environmental shifts and events is attempted here for the first time. This is based on theExpand
Bennettitalean foliage in the Rhaetian-Bajocian (latest Triassic-Middle Jurassic) floras of Scania, southern Sweden.
Cuticular analysis, associated fossils and sedimentological indices suggest that the Scanian Triassic–Jurassic bennettitaleans occupied relatively moist habitats but probably experienced physiological drought via growth on low-nutrient and low-pH substrates. Expand
Australian Jurassic sedimentary and fossil successions: current work and future prospects for marine and non-marine correlation
Strata of Jurassic age occur extensively across onshore Australia, but they are predominantly of non-marine origin. Marine Jurassic strata have only limited onshore exposure in northwestern andExpand
