The indusium is like that of AUantodia, the lower ones ai-e often double as in Diplazium, it has hardly a right to a pketi
Asplenium, Athyrium, or Diplazium, and would be better placed next to AUantodia in a genus distinguished by free venation.

Sori indusiate linear all or the lowermost only double, i. e. the receptacles occupy both sides of the veins. Indusium narrow,
membranaceous, plane or fornicate ; in the double sori affixed in pairs back to back on opposite sides of the same venule, one opening

Fronds herbaceous or coriaceous, simple pinnate or variously compound. Ehizome short, erect, rarely sub-arborescent, (The
limit between Asplenium and the present genus is not very definite, in consequence of some species having but few of the double sori, notwithstanding
which Dipkzium has been almost universaUy admitted since the time of Swartz, by whom it was founded) (Moore.)
