英文摘要 | Septomedullopitys szei sp. nov. is described from the Wuchiapingian Wutonggou Formation of Tarlong Valley, southern Bogda Mountains, Xinjiang, in northwestern China. The stem has a heterogeneous pith ca 15-20 mm in diameter, and containing numerous linear secretory ducts and parenchymatous bands. Primary xylem is endarch and the tracheids contain scalariform thickenings. Secondary xylem is of the Protophyllocladoxylon type. Comparisons with contemporaneous gymnospermous woods containing either heterogeneous pith with ducts or Protophyllocladoxylon-type secondary xylem from the Angara palaeocontinent indicate that the Tarlong stem represents a new Permian morphotaxon for the region. The presence of coprolites, borings, and spindle-shaped cavities within the stem suggests well-developed animal-plant-fungi interactions. The occurrence of numerous growth interruptions and absence of true growth rings within the stem suggest weak seasonality of annual precipitation.-The interruptions suggest a humid climate with short-term, nonperiodic droughts.
