- Diagnosis
- Phylloclades amphistomatic. Adaxial cuticle thicker than the
abaxial one. Cells of the adaxial and abaxial epidermis quadrangular to
polygonal, elongate to short. Periclinal cell walls smooth on the adaxial
surface and with several flattened papillae on most of cells on the
abaxial surface. Stomata scattered randomly on both surfaces, oriented
longitudinally to obliquely on the adaxial epidermis, and longitudinally
to irregularly on the abaxial epidermis. Inner anticlinal walls of the subsidiary
cells sometimes thickened, forming a cuticular rim around the
stomatal pit.
