3. Inner tepal margins dentate
4
3. Inner tepal margins entire to crenulate
7
4. Inner tepal scarcely reticulate, the the tubercle (basal medial callosity of inner tepal) smooth and acute at the tip
5
4. Inner tepal alveolate-reticulate, the tubercle (basal medial callosity of inner tepal) verrucose and obtuse at the tip
6
5. Larger leaf blades 20-40 cm long
