the receptacles opposite, on the lower parallel portions of proxi- 

 mate venules. Indusimn linear, plane, membranaceona, opening 

 (in each pair) on the side towards the connivent opposite sorus. 

 Veins forked from a central costa ; vemiles parallel and soriferons 

 below, anastomosing near the margin in elongated unequal hexa- 

 gonal areoles ; the marginal angles emitting short free minlets. 



Fronds simple herbaceous. Rhizome short, erect. — This genus 

 is known by its comparatively regular oppositely-placed sori, 

 analogous to those of iScolopendrium.

Sori indusiate, linear, unequal, scattered; the receptacles 

 opposite and face to face on the sides of the areoles, sometimes 

 connivent. Indusia linear, membranaceous ; those within the 

 same areoles opening face to face. Veiiis radiately-forked ; the 

 vemiles anastomosing in several series of unequal elongated 

 areoles, the sides of which are soriferous ; marginal areoles small 

 and obovate. 



Fronds simple, distinctly stipitate, rotundly flabellate or obo- 

 vate, sometimes broader than long. Ehizome short, erect. — A 

 very remarkable plant, with a distinct stipes as long as the 

 radiately-veined fronds, which are generally quite abrupt at the 

 base, or obtusely wedge-shaped. The sori are irregular in their 

 disposition, but following the veins, are more or leas radiately 

 disposed,

Sori indusiate, linear or oblong, scattered, often solitary in 

 the costal areoles and on the marginal venules ; usually connivent 

 in irregular unequal pairs, face to face, on the adjacent veuxJes of 

 the secondary areoles ; the receptacles seated on the sides of the
