Other claims from this paper (5)
- Observation Hydrocharitaceae pollen was usually inaperturate and spheroidal to subellipsoidal, except monosulcate Stratiotes aloides and Halophila ovalis.
- Observation Pollen exine ornamentation included spinules with tubercles, warts, granules or wrinkles.
- Observation The exine had three indistinct layers with only slightly developed columellae.
- Observation Pollen characters supported treating Stratiotes and Hydrilla as separate tribes.
- Observation Hydrocharitaceae exine resembled that of Alismataceae, Aponogetonaceae and Butomaceae, while prevalent inaperturate pollen suggested affinity with Najadales.
