Caudez tuftc<l, somewhat creeping, sparingly scaly at the crown. Scales lanceolate, dark brown, 

 cellulose. Fibres slender, branched. 



Stijfes variable, sometimes quite short, usually about a third of the length of the frond, smooth, 

 dark brown at the base, green upwards, scinitorete ; terminal and adherent to the caudcx. /tachut 

 green, slender, slightly grooved in front. 



Vertiatum circinate. 



Fronds two or three inches to eight or ten iuches long, linear, pinnate. Pinnw delicately herbaceous, 

 palish green; variable in form, usually roundisk*ovnte» and somewhat cuncate at the base, or more

 inciso-crenatv, except at the cuneate base, which is entire. Occasionally the pinmu are equal-sided ami 

 broadest at the base, much shortened and rounded at tho apex; and sometimes they are more elongated 

 and acute. 



Venation consisting of a midvein, producing forked tcitui at the base of the pinnae and simple ones
