Malloranga dentata (Euphorbiaceae: Acalyphoideae): A new fossil species from the Miocene of New Zealand
چکیده انگلیسی
A new fossil species of Malloranga is referred to the Mallotus-Macaranga clade (Euphorbiaceae: Acalyphoideae) on the possession of broadly ovate, dentate leaves with a marginally attached, pulvinate petiole, pocket acrodomatia, 3-5 lateral primary veins, agrophic secondary veins, percurrent tertiary and quaternary venation, looped marginal venation, characteristic rounded, paired, basal extrafloral nectaries and disc-shaped, peltate glandular scales. The taxon includes previously reported 'aff. Euphorbiaceae' leaf impression material from the Lower Miocene of New Zealand and is here described as Malloranga dentata sp. nov. It is present in oil shale from the Nevis Valley and mudstone from Lauder, Manuherikia Valley; both palaeolacustrine deposits from the former Lake Manuherikia in what is now Central Otago, southern New Zealand.
