Abstract

Woodwardia bureiensis Fedotov, Dryopteris sp. and Osmunda sachalinensis Krysht. were first reported in the Paleocene Wuyun flora from Jiayin County, Heilongjiang Province, China, and they are also new records to China. Woodwardia bureiensis is different from other species of the genus in that the pinnules of sterile fronds have a closed space with touching margin. The pinnules of Osmunda sachalinensis Krysht. from Wuyun flora are broadly cuneate at their base, while those of O. greenlandica (Heer) Brown, described from the same flora previously, expand at the pinnule base.

Key words： Woodwardia; Dryopteris; Osmunda; Paleocene; Wuyun flora; China.
