“…Protophyllocladoxylon francisiae (Pujana et al, 2014) is dissimilar from the specimens here in that the crossfield pits are elongated and contiguous where two are present, unlike those of P. owensii, and come from the Eocene of Antarctica.…”

“…Of the 29 species of Protophyllocladoxylon thus far described (Zhang et al, 2010;Pujana et al, 2014) only four have the following characteristics in common with the specimens described here: marked growth rings, uniserate rays with heights including approximately 2-18 cells, uniserate and biserate (rarely triserate) tracheid pitting, alternate where biserate or triserate, oval and/or sub-hexagonal, and 1-2 simple circular to ovoid pits per crossfield and lack axial parenchyma. These species are P. francisiae Punjana, Santillana et Marenssi (Pujana et al, 2014)…”

“…Protophyllocladoxylon contains 29 described species, in addition to the new species P. owensii, with a cosmopolitan distribution and temporal range that extends from the Carboniferous to the Eocene (Zhang et al, 2010;Pujana et al, 2014).…”

“…The taxon also displays a high amount of morphological diversity (Pujana et al, 2014). Some species, including the type species, have only araucarian type tracheid pitting, while others have the mixed type (e.g.…”

“…P. oolithicum; Vogellehner, 1966). Pujana et al (2014) state that pitting arrangement is a key feature for classifying at ranks such as family and genus, and thus this diversity of character states may be problematic in a taxonomic context. Alternatively, the differences may be correlated to developmental stage or age of the tree, or due to environmental impacts on growth.…”

et sp. nov., is described from the uppermost part of Guodikeng Formation in South Taodonggou section, Turpan-Hami Basin, Xinjiang Uygur Autonomous Region, northwestern China. It is characterized by a solid pith, endarch primary xylem and pycnoxylic wood. The pith is composed of parenchyma and sclereids. Radial walls of primary xylem tracheids have spiral and scalariform thickenings. Secondary xylem consists of thickwalled tracheids and parenchymatous rays. Uniseriate rounded pits with oval apertures are distributed on radial tracheidal walls separately. Cell walls of rays are homogeneous and smooth. Rays are 1-10 cells high in tangential section. Cross-field pits are cupressoid. There are 1-4 bordered pits with slit-like to oval apertures in each cross-field. Based on the anatomical features of the pith and xylems, it is proposed that the new stem has a coniferous affinity. The new fossil stem adds to the knowledge of vascular plant diversity close to the Permian-Triassic boundary.

Ten embedded fossil logs sampled in situ from the middle Eocene volcano‐sedimentary rocks close to Suffield Point in the Fildes Peninsula, King George Island, Antarctica, are assigned to Protopodocarpoxylon araucarioides Schultze‐Motel ex Vogellehner, Phyllocladoxylon antarcticum Gothan, Agathoxylon antarcticum (Poole & Cantrill) Pujana et al., A. pseudoparenchymatosum (Gothan) Pujana et al. and an unidentified angiosperm wood. Differences in the taxonomic representation and growth‐ring characters of the Eocene woods on King George Island and coeval assemblages from Seymour Island, on the western and eastern sides of the Antarctic Peninsula respectively, are interpreted to result from environmental and climatic gradients across the Peninsula Orogen during the early Palaeogene. In particular, a precipitation gradient inferred across the Peninsula at that time might have been induced by a rain‐shadow effect.
