Rhizome wide-creeping, subterraneous, pink-tinted, 1-stelical, scaly, the 

 scales remote, deciduously flocculent, those of the extremity ovate-oblong, 

 acuminate, lacerate-denticulate, pink-tinted, crowded. Shoots erect, 45 — 65 

 cm. high, the lower part simple, terete or subterete, deciduously pubescent, 

 pink-tinted at least towards the slightly compressed and somewhat grooved 

 base, the base 2 — 4 mm. thick, the upper part copiously branched, broadly 

 ovate, triangular or pentagonal in outline, 20 — 30 cm. long, 20 — 30 cm. 

 broad at or near the base; rachises pubescent beneath; pinnae many, 

 contiguous, ascending, the higher simple or forked, very short, the lower 

 the largest, stalked, 8 — 4-pinnate; pinnulae ascending, contiguous, the 

 higher simple or forked, the lower pinnately compound, the lowest 

 posterior not rarely produced; ultimate branchlets contiguous, 5—15 mm. 

 long, 3 — 5 mm. broad including the lateral leaves. Leaves of the stipe 

 and lower part of the main and secondary rachises erect, very distant, 

 isomorphous, triangular, acute, minutely denticulate, peltate and truncate 

 at the base; leaves of the branches heteromorphous, flaccid, herbaceous, 

 bright-green or bluish above, pale-green beneath; lateral leaves sub- 

 rhomboidal-oblong; those of the principal rachises distant, horizontal or 

 Fern Allies. 10
