Relationship to other plants
Aglaophyton was at first thought to be a species of the vascular plant genus Rhynia which lived at the same time. Later it was discovered that it is not really a vascular plant. It had vascular tissue, but the cells had thin walls. It might therefore be a missing link between the Bryophytes and Horneophyton and the vascular plants like Rhynia.
In 2004, Crane et al. published a cladogram which has Aglaophyton as the sister group of the vascular plants.[1]
