Three new fossil records of Equisetum (Equisetaceae) from the Neogene of south-western China and northern Vietnam

Three fossil species of Equisetum (Equisetaceae) were reported from the Neogene of south-western China and northern Vietnam, based on well-preserved rhizomes with tubers, improving the understanding of species richness and their distribution range during the Neocene in Asia.

Out of New Guinea? Two new species of Zygogynum (Winteraceae) extend the genus west of Lydekker’s and Wallace’s Lines

The genus Zygogynum is currently thought to have a Papuasian-Pacific distribution and is only known from the western Pacific islands, but is not yet recorded from islands to the west of the Sahul Plate and the biogeographic boundary of Lydekker's Line.



The first fossil Microsoroid fern (Palaeosorum ellipticum gen. et sp. nov.) from the middle Miocene of Yunnan, SW China

The microsoroid ferns make up a large group in the family Polypodiaceae, easily characterized by the combination of at least partly clathrate rhizome scales and anastomosing reticulate venation. The

Late Miocene Palaeocarya (Engelhardieae: Juglandaceae) from Southwest China and its biogeographic implications

It is proposed that the wide distribution of Palaeocarya and relatively narrow distributions of close relatives, Engelhardia, Alfaropsis, and Oreomunnea, might be associated with a stepwise cooling and a major ice sheet expansion in the Antarctic and Arctic from the late middle Miocene to early Pliocene.

Miocene leaves of Elaeagnus (Elaeagnaceae) from the Qinghai-Tibet Plateau, its modern center of diversity and endemism.

The diversification of Elaeagnus in the Qinghai-Tibet Plateau and adjacent areas might have been driven by continuous uplift at least since the late Miocene, causing formation of complex topography and climate with high rainfall seasonality.

First occurrence of Cedrelospermum (Ulmaceae) in Asia and its biogeographic implications

Cedrelospermum (Ulmaceae) is an extinct genus with extensive fossil records in Europe and North America that originated in North America and dispersed into Asia via the Bering land bridge from the Eocene to Oligocene, where a southward retreat of the genus distribution probably took place.


This paper describes a new species of fossil wood, Wataria yunnanica Li et Oskolski, from the Dajie Formation of the middle Miocene in southern Yunnan province, China. This species shows the greatest
