| 英文摘要 | As an early land plant previously reported from the Upper Silurian (Pridoli) of Xinjiang, Northwest China and Central Kazakhstan, the circumscription of Eocooksonia sphaerica (Senkevitsch) Doweld remains ill-defined because of the paucity of specimens and poor preservation in marine deposits. New specimens of this plant are described from the Pridoli-aged Wutubulake Formation of the Junggar Basin, Xinjiang. New observations and comparisons with the type material from Kazakhstan confirm the pseudomonopodial branching pattern, which forms an apparent main axis with lateral dichotomously branching systems. Our specimens demonstrate that the terminal sporangia of Eocooksonia Doweld consist of a central body and a border with four to eight elongate-triangular emergences, a character shown in the published illustrations of the type material but not mentioned in the original diagnosis. Eocooksonia may be close to Cooksonia Lang and Pertonella Fanning, Edwards et Richardson in affinities, particularly to the latter that has terminal discoidal sporangia with spiny emergences. It is deduced that the sporangial central body of Eocooksonia contains sporogenous tissues, which are covered by a distal surface wall with radiated emergences. One sporangium specimen of an unnamed plant is also described from the Wutubulake Formation of Xinjiang; it shows a central body with a wide border lacking emergences, and represents a taxon superficially similar to Eocooksonia.
