Other claims from this paper (6)
- Observation Bonnetiaceae nodal anatomy was trilacunar with three traces or unilacunar with one trace.
- Observation Bonnetiaceae leaves had a medullated petiole vascular cylinder, paracytic stomata and mesophyll mucilage cells.
- Observation Bonnetiaceae leaves showed upper surface periclinal divisions and discrete phloem patches within vascular bundles.
- Observation Some Bonnetiaceae genera had foliar vascular bundle sheaths with inner fiber layers and an outer endodermis with Casparian strips.
- Observation Bonnetiaceae leaves varied in lamina and cuticle thickness, palisade and spongy layers, venation, sclereids and crystals.
- Observation Foliar anatomy supported subgroup recognition and separation of Bonnetiaceae from Theaceae.
