- Observation Helicteres pollen grains were usually triporate, oblate or suboblate, triangular in outline, and medium sized.
- Observation Helicteres exine surface showed great variability.
- Observation Nine Helicteres pollen types were distinguished by exine sculpture.
- Observation Neoregnellia shared pollen type IX with Helicteres sections Sacarolha and Orthothecium.
- Observation Kleinhovia and Helicteres pollen shared shape, size, and apertures, differing in the former’s microreticulate surface.

- Observation Pterospermum acerifolium pollen morphology supported separation from Helictereae.
- Observation Exine sculpture patterns distinguished four monospecific Helicteres sections.
