Shoots erect, or ascending from a creeping base, 30 — 60 cm. more or 

 less long, the lower part simple, 2V2 — 4 mm. thick at the base, 3-stelical, 

 the upper part pinnate, the stem pale-grey-brown, rough with more or 

 less deciduous, minute, papiUiform warts; pinnae moderately close, 

 ascending, lanceolate, to 20 cm. long, 3 — 4 cm. broad near the base; 

 pinnulae erecto-patent, close, simple or forked, 3 — 5 mm. broad including 

 the lateral leaves. Leaves of the stipe erect, remote, subulate- or 

 lanceolate-triangular, entire, equally or obliquely cordate at the base, the 

 auricles incurved; leaves of the branches heteromorphous ; axillary leaves 

 conspicuously hastate at the base; leaves of the lower plane subspreading 

 or more ascending; of the secondary rachises close or remote, triangular- 

 or subrhomboidal-oblong, subfalcate, rather acute, entire, the upper side 

 somewhat pellucid-margined, rotundate-cuneate in the lower part, the

 adpressed, spur-like auricle, the lower side somewhat produced and truncate- 

 subauriculate at the base, the largest leaves 8 — 4 mm. long, and IV2 — 2 

 mm. broad at the base; of the branchlets contiguous or subimbricate, 

 similar but somewhat smaller, more falcate, with the basal auricle still 

 smaller, or wanting in the higher leaves; leaves of the upper plane erect; 

 of the secondary rachises remote, lanceolate, pellucid-margined, acute or 

 bluntish, entire, very obliquely attached, more or less cordate and hamato-
