摘要

摘要/ Abstract摘要:在晚渐新世Fossil-Lagerstätte Enspel (Westerwald, Germany)发现了马铃薯科植物Groenlandia pescheri D. Uhl & Poschmann sp. nov.。该种的特点是叶的排列亚相反，在叶基部没有可观察到的托托状附属物，外果皮很薄(这两个特征都是水生属Groenlandia J. Gay的特征)，有一个尖刺的冠(不同于该属中唯一的其他物种，现代的Groenlandia densa (L.))。四)。该分类群代表了Groenlandia属的第一个前第四纪记录，通常被认为是所有其他Potamogetonaceae的基姐妹群。

Groenlandia pescheri sp. nov. (Potamogetonaceae) from the Late Oligocene Fossil-Lagerstätte Enspel (Westerwald, Germany)

Abstract The new species Groenlandia pescheri D. Uhl & Poschmann sp. nov., belonging to the family Potamogetonaceae, is described from the Late Oligocene Fossil-Lagerstätte Enspel (Westerwald, Germany). The species is characterized by sub-oppositely arranged leaves without observable stipule-like appendages at the leaf bases and a very thin exocarp (both characteristics of the aquatic genus Groenlandia J. Gay) with a spiked crest (which differs from the only other species included in this genus, the modern Groenlandia densa (L.) Four.). The taxon represents the first pre-Quaternary record of the genus Groenlandia, which is usually regarded as a basal sister group of all other Potamogetonaceae.
