A Late Devonian plant assemblage from New South Wales, Australia: Diversity and specificity

Gondwanan floras of Late Devonian age are poorly known. In Australia, the rare studies that have been published on plants old and need reinvestigation. This paper is an account plant macro- micro-remains found in Mandowa Mudstone at Barraba, New South Wales. According to miospores, late latest Famennian age. The record anatomically preserved specimens diversified, with nine taxa assigned Lycopsida, Cladoxylopsida, Iridopteridales Archaeopteridales. One specimen referrable spermatophytes. Several specific i.e., lycopsid genera Cymastrobus Lycaugea, iridopteridalean genus Keraphyton, cladoxylopsid species Polyxylon australe, possibly a represented by large Hierogramma branch showing exarch protoxylem strands. adpression dominated axes cosmopolitan Leptophloeum. It also includes interpreted as seed such possible ovule resembling Pseudosporogonites, two types foliage differing their petiole width. this consists delicate fronds broadly comparable those Cosmosperma. closest flora from Barraba Famennian–earliest Tournaisian Albany Shale eastern USA, suggesting floral connexion environmental conditions between Northern Gondwana Southern Laurussia.
