Other claims from this paper (7)
- Observation Hoplestigma pollen has 3-colporate apertures bordered by six meridional ridges separated by three intercolpar concavities.
- Observation Pollen similar in SEM and TEM to that of Hoplestigma is found in Bourreria and Ehretia of the Boraginaceae.
- Observation This pollen type is also common in the Myrtales.
- Observation The Hoplestigma pollen type is not known to occur in either the Violales or the Ebenales.
- Observation The parietal placentation of Hoplestigma is not typical of the Ebenales.
- Observation Hoplestigma differs from Myrtales in having petals united basally and unitegmic ovules, whereas Myrtales have distinct petals and bitegmic ovules.
- Recommendation Until Hoplestigmataceae is examined for internal phloem, the authors defer to Takhtajan's placement of the family in the Boraginales.
