- Observation Secondary pollen presentation occurs in Spigelia.
- Observation A pollen deposition mechanism was observed in living Spigelia anthelmia material.
- Observation A pollen deposition mechanism was observed in living S. marilandica material.
- Observation A pollen deposition mechanism was observed in living S. splen-dens material.
- Observation Pollen loads suggest a deposition mechanism in S. longi-flora.
- Observation Pollen loads suggest a deposition mechanism in S. sellowiana.
- Observation The upper Spigelia style detaches after anthesis.
- Mechanism Style rupture may promote prezygotic selection in Spigelia splendens.
- Mechanism Style rupture is hypothesized to select fast pollen tubes in Spigelia anthelmia.
- Observation Fast pollen tubes can penetrate ovules before style detachment.
- Observation Slow pollen tubes remain on the detached upper style.
- Observation Spigelia onthelmia is interpreted to trade lower seed set for fitter progeny.
- Observation Spigelia anthelmia is the only genus member found on other continents.
- Observation Spigelia anthelmia is a pioneer plant and weed in tropical Africa and Asia.
