Notes
This species has been called E. callifolium but differs strikingly from the typical E. callifolium of Java in its much larger flat rhizome-scales and proportionately narrower, more rigid fronds. Fronds on smallish plants mostly have rather short stipes and much-decurrent lamina, and such plants may bear fertile fronds. In the type collection one specimen has a fertile frond with stipe 8 cm and lamina 18 by 2 cm, base narrowly decurrent, the other has stipe 15 cm, lamina 24 by 2.2 cm, base rather abruptly narrowed. The latter also has costa deeply grooved on upper surface and very prominent below, the former has costa shallowly grooved above and not very prominent beneath.
