Other claims from this paper (14)
- Observation Leaf and bract epidermal cells had raised, convex outer periclinal walls on both surfaces.
- Observation Capsule wall epidermal cells were polygonal with flat outer periclinal walls.
- Observation Leaf and bract stomatal complexes were paracytic.
- Observation Capsule wall stomatal complexes were anomocytic.
- Observation Leaf stomata on both surfaces were coplanar to the epidermis.
- Observation Bract adaxial stomata were raised.
- Observation Capsule wall stomata appeared slightly sunken.
- Observation Capsule wall stomata were larger than leaf and bract stomata.
- Observation Bract abaxial stomatal index was 9.4 versus 4.7 adaxially.
- Observation Leaves had the highest stomatal index, followed by bract and capsule wall.
- Observation Leaf and bract indumentum contained glandular and nonglandular trichomes with greater abaxial density.
- Observation Capsule wall indumentum lacked nonglandular trichomes.
- Observation Epicuticular wax formed striations whose pattern varied among organs.
- Mechanism Epidermal morphological disparities help explain physiological divergence among the organs.
