英文摘要	Aralia stratosa H. Zhu, Y.J. Huang et Z.K. Zhou sp. nov. is described based on fossil endocarps from the upper Pliocene of northwest Yunnan in southwest China. The endocarps are characterized by a semicircular to elliptic outline in the lateral view, an apical beak-like structure bending towards the ventral side, and a transversely wrinkled surface, collectively indicating taxonomical inclusion in the genus Aralia (Araliaceae). The new fossil taxon is compared with nine extant species of Aralia based on endocarp morphology and anatomy, showing the carpological resemblance to A. echinocaulis. Aralia stratosa sp. nov. represents the first confirmed fossil record from lower latitudes in the Northern Hemisphere. This implies a southerly biogeographical range for this genus than was previously interpreted. The fossil record of Aralia suggests a Cretaceous origin in North America and an Eocene dispersal to eastern Asia, likely via the Bering land bridge, followed by Miocene establishment in Europe. The genus likely began to inhabit lower latitudes in eastern Asia no later than the late Pliocene, which is in line with results from molecular analyses. All these may suggest a southward distributional change probably associated with the global cooling and northern acidification. (C) 2015 Elsevier B.V. All rights reserved.
