A monocotyledonous leaf macrofossil taxon from Golden Grove in Adelaide, South Australia is recognised as being close to several extant Australasian species of Cordyline, especially those in the C. stricta (Sims) Endl. / C. fruticosa (L.) A. Chev. complex. The fossil is assigned to the form genus Paracordyline, known previously from the Oligocene Kerguélen Islands. However, as the Golden Grove taxon differs markedly from the Kerguélen species, it is considered to be a new species, P. aureonemoralis Conran & Christophel. 相似文献

Understanding the composition of an artefact has ramifications for advancing human history and behaviour knowledge, providing cultural information about trade, agricultural practices and adaptation to new environments. However, accurate plant identification from artefacts is problematic, since textile production, age, dirt and/or conservation treatments obscure morphological features, and specimen size and/or ethical considerations hamper modern analytical methods. This study tested the efficacy of polarized light microscopy (PLM) in the identification of New Zealand plant species commonly used in Māori textiles, and demonstrates that morphological and birefringent features observed using PLM have the potential to distinguish between‐ and within‐plant genera. 相似文献
