Other claims from this paper (5)
- Observation The stomatal index is less variable than mere stomatal frequency.
- Observation In convergent leaf forms, structural differences in the cuticle will almost always distinguish isolated leaves.
- Observation The distribution of cuticular elements may often discriminate closely related taxonomic groups.
- Recommendation Statistical characters such as size or frequency of cuticular elements must always be used with extreme caution.
- Recommendation Individual cuticular and other epidermal characters cannot be considered in isolation in taxonomic work.
