deutsche Version

In addition to the flexible hairs arising from broad bases (here on the right), the "hair bearing plant" has got short stiff spikes (here on the left). If hairs or spikes are seen on samples, one can be sure it is Trichopherophyton since no other plant in the Rhynie chert has got any.
Obviously these structural details are meant to prevent herbivores creeping up to the sporangia. Therefore they are not found on the lower parts of the plant, which makes it difficult to recognise this plant if no parts with bristles are around.
