Shoots ascending from a creeping base, 10—15 cm. long, the lower 

 part simple, short-stipitiform (1 — 4 cm. long), the upper part branched, 

 ovate-lanceolate in outline ; lower pinnae pinnate, 3 — SVt cm. long, higher 

 simple or forked; pinnulae few, 2 — 4 on a side, hardly more than 1 cm. 

 long, simple or rarely forked. Leaves heteromorphous on both stem and 

 branches; those of the lower plane spreading, obliquely falcate-ovate, 

 unequal-sided; those of the stipe and main rachis the largest, to S'l-z mm.

 base, broadly rotundate-cuneate on the upper sfde at the base, entire on 

 the lower edge except towards the apex, minutely denticulate and pellucid- 

 margined on the upper side; those of the branches growing gradually 

 smaller; of the ultimate branchlets 27* mm. long, hardly V2 mm. broad; 

 leaves of the upper plane unequal-sided, oblique-ovate, cuspidate, slightly 

 keeled towards the apex, narrowly pellucid-margined on both sides and 

 minutely denticulate except at the base, sparingly pellucid-dotted, rotundate- 

 cuneate on the inner side, shortly and narrowly rotundate-truncate and
