PALEOZOIC PLANTS FROM CHINA. 17 



" Fossile Flora dor Bäreuiusel " and called by him Kiiorria 

 Inihricata. That the Knorriac represent subepidermal states of 

 preservation of lepidodendroid })lants is a fact long- known to 

 palœobotanists. 



Together with this Knorrla, there was found a .small imperfect 

 fragment of a fern, apparently of a Fecoplerls, but which is hardly 

 worth figuring.

LEPIDODENDRON si.

A slab of a weathered fine-grained sandstone bears an 

 impression of the inner surface of the cortex of a plant which is 

 probably a Lepidodendron. The print consists of numerous 

 shallow rhombic depressions, mostly covered with a coaly crust, 

 and now and then showing a slight protuberance at their centres 

 which may be looked upon as the bundle-trace. The diameters 

 of the rhombs measure 10-15 mm. and 5-8 mm. 



The preservation is such as does not allow any precise 

 determination.
