Morphology
Specimens from the Peninsula Malaysia have a rather regular venation, and small sori regularly in two rows between the veins, the rows clearly slanted upwards, following the pattern of the veins. Specimens from other localities have larger sori, more often in alternating rows between the veins, resulting in rows apparently slanted downwards, across the pattern of the veins.
