Abstract Two diminutive new taxa of the family Zosterophyllaceae, Parazosterophyllum timsiae gen. et sp. nov. and Gippslandites minutus gen. et sp. nov., are described from the upper Silurian–Lower Devonian of Victoria, Australia. No internal anatomy was preserved in either. It is the first time that new plant genera have been described from either the lower plant assemblage of Ghin Ghin Road near Yea or the Boola Siltstone at Tyers. The relevant stratigraphy is reevaluated, with a brief discussion concerning the interconnectivity of the Victorian with South Chinese Plate floras. Tentative explanations for the terrestrial source of Parazosterophyllum timsiae and Gippslandites minutus are presented, based on palaeocurrent flow and landmass positions from other workers.

来自澳大利亚维多利亚上志留统-下泥盆统的两个新属的早期气管植物（Zosterophyllaceae）

摘要 Zosterophylllaceae 科Parazosterophyllum timsiae gen 的两个小型新分类群。等 sp. 十一月 和 Gippslandites minutus gen。等 sp. 11 月，描述于澳大利亚维多利亚的志留纪-下泥盆纪。两者都没有保留内部解剖结构。这是第一次从 Yea 附近的 Ghin Ghin 路较低的植物组合或 Tyers 的 Boola 粉砂岩中描述新的植物属。重新评估了相关地层，并简要讨论了维多利亚时代与华南板块植物群的相互联系。根据其他工作人员的古洋流和陆地位置，对 Parazosterophyllum timsiae 和 Gippslandites minutus 的陆地来源进行了初步解释。Farghus R.
