Caudex creeping, about as thick as a crow’s quill, producing the 
fronds at irregular intervals, almost black, with a few scattered 
ovate scales on the younger portions. Fibres branched, rigid. 
Vernation circinate. 
Stipes lateral and adherent to the rhizome, slender, longer than 
the frond, often twice as long, dark-brownish-purple at the base, 
paler upwards, sparingly furnished especially near the base with 
ovate-lanceolate scales. Rachis narrowly margined above, and 
together with the secondary rachides, which are also margined, 
sometimes tinged with purple.
