Abstract:

Two fossil reproductive organs of early angiosperms were collected

from the Yanji Basin, Jilin Province of China. The assemblage of fossil plants

consist mainly of pteridophytes, gymnosperms and a few angiospoermms. The present

paper only reports the two reproductive organs of angiosperms. They are

Archimagnolia rostrato-stylosa gen.et sp. nov., Eucommioites orientalis sp.nov. The

first is a slightly elongated floral axis(receptacle), with about 20 carpels

helically arranged. The carpels are free from each other and attenuated into a

beak-like structure at the apex, with the base inserted into the receptacle. A com-

parison with living plants indicated its close relationship with some members of

the Magnoliaceae. The second is a samara, similar to a fruit of the genus

Eucommia, narrow-oblong, 2-lobed at the apex with the lobes stigmatic on the

inner side. The seed is situated at the middle of fruit, oblong in shape.
