- Leaf arrangement bipinnatisect.
Primary lobes up to 15 mm long. Secondary
lobes up to 7 mm long, linear, entire, apex
blunt or mucronate. Secondary lobe sinus
angular and acute. Midvein clearly visible.
Secondary venation brochidodromous. Cuticle
thick, and cuticular flange between epidermal
cells well developed. Normal epidermal cells
isodiametric, randomly shaped, commonly pentagonal
or hexagonal. Anticlinal cell walls
on non-stomatal surface usually straight. Striations
present on epidermal cells. Leaves
hypostomatic, long axis of guard cells usually
parallel to midvein. Stomates usually paratetracytic,
about 32 ~tm long, 26 ~m wide. A
T-piece of thickened cutin often visible at poles
of guard cells. Trichome base single-celled,
with a thickened ring of cuticle, present on
both leaf surfaces, but more frequent on
stomatal surface.
