NOTES The most widespread species of Vietnam and of the whole Southeast Asia ( Khotimperwati et al . 2018 ). The side leaves are elongate-ovate with tridentate apex. The most important character is the underleaf, consisting only of hyaline cells, except for a few green basal cell rows. According to their shape four varieties are distinguished. These have been described originally, as separate species, but they are interconnected with many transitional forms ( Pócs 1969 ).
