115a. ALLANTODIA, R. Br. (in part). 
Vernation fasciculate, corm decumbent. Fronds pinnate, 
2-3 feet long, sub-erect; pinnae linear, membranaceous, 4-6 
inches long, 1 inch broad. Feins forked near the midrib, anasto- 
mosing towards the margin, forming two rows of liexagonoid 
areolae bounded by a continuous marginal vein. Sporangi- 
ferous receptacles unilateral on the lower part of the veins. 
Indusium vaulted, cylindrical, forming linear sori. 
Obs. — This genus is now restricted to a single species; it 
originally contained a group of species, which now form the 
section Athyrium of the genus Asplenium (p. 219) : they differ 
in having large decompound fronds and free venation, agreeing 
only with the present genus in having turgid indusia, which is 
not uncommon to other species of Asplenium. 
The name Allantodia is derived from the Greek allantos, a 
sausage, the indusium before bursting resembling a miniature 
sausage in shape and colour. 
Genus 115a. — Portion of fertile frond, natural size, and ditto magnified.
