The surface structure of the foliar epidermis of 5 species,
2 forms and 8 populations in Neolepisorus was
investigated under light microscopes. The result shows
that their stomata are distributed in the lower leaf
epidermis and parallel to the veins. The types of stomata
found were polocytic, axilloctytic, copolocytic,
coaxilloctytic and anomotetracytic. They were different in
stomatal type, stomatal index, the epidermal features, type
of curved anticlinal walls. These differences contributed
evidences for the taxon identification and systematics of
Neolepisorus.
Key words:
Neolepisorus, leaf epidermis, stomatal apparatus
