Diagnosis
Reference | Diagnosis | |
---|---|---|
H. Mustafa 2003 | Lanceolate leaves up to more than 30 cm long and 7 cm wide, with midrib 1–9 mm thick and more or less perpendicular lateral veins of about 26–40 mm per 10 mm. Leaf and lamina margins entire, stomata of haplocheilic type, subsidiary cells 3– 6 arranged as a ring around the guard cells. | |
A. Abu Hamad et al. 2008 | Leaves amphistomatic. Epidermis of upper leaf surface clearly differentiated into costal and intercostal fields. Costal fields of upper leaf surface 1–6 (usually 3–4) cells wide; cells of costal fields elongated trapezoid–polygonal to rectangular. Intercostal fields 4–12 cells wide; cells usually shorter to isodiametric. Stomata restricted to costal fields, irregularly distributed and oriented; stomatal complexes usually monocylic to incomplete dicyclic; guard cells with small flap-like ledges; 4–8 subsidiary cells per stomatal complex. Epidermis of lower leaf surface with narrower costal fields, 1–5 cells wide; intercostal fields up to 10 cells wide. Stomata more frequent on lower leaf surface, restricted to costal fields, more-or-less evenly distributed and randomly oriented. Stomata on lower leaf surface similar to those of upper leaf surface; stomata vary in shape, including monocyclic, incomplete dicyclic, and stomata without well-developed neighbouring cells. |
