| 5 | Figs usually cauliflorous, the receptacle 1.5-5(-10) cm diam. when dry |
| 5' | Figs in the leaf axils (or on minute spurs on the older wood), 0.3-0.8 cm diam. when dry |
| 6 | Tertiary venation scalariform and lateral veins usually 6-10 pairs |
| 6' | Tertiary venation reticulate (to subscalariform) and/or lateral veins usually 3-6 pairs |
| 7 | Lateral veins and smaller veins of the lamina prominent beneath; the hairs on the lamina often ± patent |
