Other claims from this paper (11)
- Observation D. bulbifera and D. oppositifolia each had six stomatal types.
- Observation D. hispida and D. wallichii each had four stomatal types.
- Observation D. belophylla had three stomatal types.
- Observation D. alata had only two stomatal types.
- Observation Anomocytic stomata predominated except in D. bulbifera, where tricytic stomata predominated.
- Observation Cyclocytic stomata occurred rarely in D. bulbifera.
- Mechanism Subsidiary cell number increases by wall formation in paracytic, tricytic or diacytic stomata.
- Mechanism Reduction of subsidiary cells in tetracytic stomata resulted from lateral cells becoming epidermal cells.
- Observation Stomatal abnormalities included single guard cells, degeneration and contiguous stomata.
- Observation Capitate glandular hairs occurred on leaves of four Dioscorea species.
- Observation Non-glandular three-celled trichomes occurred only in D. hispida.
