The ovulate structures of Umkomasia macleanii differ from other species of Umkomasia in small size, and limited geographic distribution.
Umkomasia macleanii may have been produced by the same plant as Pteruchus africanus (pollen organs) and Dicroidium odontopteroides (leaves), based on cuticular similarities between these leaves and reproductive structures at the Umkomaas locality of South Africa.[1]
