Other claims from this paper (7)
- Observation The fossil fructification was described as Bowmanites moorei sp. nov.
- Observation B. moorei has three sporophylls per whorl.
- Observation Each sporophyll has three lobes, one fertile and two sterile.
- Observation Each fertile lobe subtends two sporangia, giving six per whorl.
- Observation Sporangia are inverted and attached distally to paired axillary sporangiophores.
- Observation Spores are small, spherical, trilete and lack distinctive exine ornamentation.
- Observation The species expands known morphological variation in Bowmanites but contributes little phylogenetic resolution.
