Description edit
The leaves of Dicroidium odontopteroides differ from other species of Dicroidium in being unipinnate and having short rounded pinnae.
Whole plant reconstructions edit
Dicroidium odontopteroides may have been produced by the same plant as Umkomasia macleanii (ovulate structures) and Pteruchus africanus (pollen organs), based on cuticular similarities between these leaves and reproductive structures at the Umkomaas locality of South Africa.[2]
