when the caudex is erect. Scales lanceolate-subulate, hair-pointed, 
brown, with a dark centre and paler margins. Fibres dark-brown, 
numerous, coarse, branched, tomentose. 
Vernation circinate, the rachis often folded laterally as well as 
involutely fore and aft, the apex, however, being simply circinate. 
Stipes terminal, and adherent to the caudex, variable in length, 
usually from about one-third to one-half of the entire length of the 
frond, stout at the base, green, densely scaly ; the scales spreading, 
most numerous at the base, but usually abundant throughout the 
whole length of the stipes, and in the normal plant lanceolate- 
attenuate, and dark-centred like those of the crown, frequently 
almost black. Rachis convex behind, channelled in front, smooth, or
