- Observation Silicon was high in marginal sclereids and about half the abaxial epidermal cells.
- Observation Silicon was distributed throughout the wall rather than concentrated in knobs or warts.
- Observation A small proportion of stomata had high silicon and constricted apertures.
- Observation Leaf epidermal silicon accumulation characterized each of three other Selaginella species.
