Nothia aphylla

This reconstruction of the sporangia of Nothia aphylla was made by El-Saadawyg and Lacey (1979). Nothia is a rare plant in the Rhynie Chert and it is not yet completely understood.
Kidston and Lang thought the sporangia to belong to the plant Asteroxylon, but it turned out to be a new plant.
The stem of Nothia shows a peculiar wavy surface.
In my slides the plant did not occur. The photos are from an exchanged slide.

Stem with the characteristic wavy surface.
Width of the photo 1.2 cms.
