containing two files of stomata) present on the upper epidermis
and two bands (each band containing three to four files of
stomata) present on the lower epidermis. Stomata surrounded
by four to six subsidiary cells with unevenly developed papillae.
Trichomes and papillae absent on the periclinal cell walls.
