deeply inciso-lobate, the lobe 
multiid-erisped ; basal pair of lobes 
unequally prolonged, sometimes erisped ; apex

dez thick, short, tufted, often decumbent, scaly at the erown, Seales lanecolate-acumi 
pale purplish-brown, shining, finely rotieulato-vonose. Fibres short, branched, numerous, dark brown. 
Stipes averaging about one-third the length of the frond, but varying from about one-fourth to 
one-half 
entire length; usually clothed with pale tawny contorted subulate scales, sometimes 
smooth, purplish-brown, darkest at the base; terminal, and adherent to the caudex. Лаел, or more

Fronds from about four inches to two fect or upwards in length, narrow elongate-lanceolate, or 
broadly linear, or ob

apex п

fleshy or coriaceous, deep rich green, The varieties deviate in unnumbered forms, by the Inceration or 
cin, the multifid dilatation of the 
apex, the branching (often repeated) of the 
stipes and midrib, the loss of the cordate lobes at the base, and the arrest of 
longitudinal development
