Shoots ascending or suberect from a short-creeping base, 20 — 30 cm. 

 long, the lower part simple, stipitifoi^n, obtusely quadrangular in the 

 lower half, smooth, naked, stramineous or pale-ochraceous, 1 — IV2 mm. 

 thick, the upper part ovate or lanceolate in outline, 2-pinnate or sub-8- 

 pinnate, the rachis 5 — 6 mm. broad including the lateral leaves; lower 

 pinnae 4 — 8 cm. long, pinnate or sub-2-pinnate ; ultimate branchlets 2 — 3 

 mm. broad. Leaves heteromorphous; lateral leaves of the stipe unequal- 

 sided, obliquely ovate, to 2 mm. long by IVj mm. broad, bluntish, the 

 upper side denticulate in the upper part, gradually copiously ciliated in 

 the lower pait, broadly rounded at the base, the lower side sparingly 

 denticulate in the upper part, rotundate-cuneate in the lower part, auricled 

 at the base; of the main rachis similar but 8 mm. long by IV4 mm. broad; 

 of the branchlets less unequal-sided, ovate-oblong, 1 'A mm. long, subfalcate, 

 subacute, the upper side indistinctly pellucid-margined, rounded, at the 

 base, the lower side rotundate-truncate at the base; intermedial leaves 

 of the stipe similar to the lateral leaves but shortly acuminate, minutely 

 denticulate on both sides; of the main rachis similar but shortly aristate, 2 'A 

 mm. long and TA mm. broad, the cusp 'A as long as the blade; of the 

 branchlets similar but smaller, and the cusp proportionally a little longer. 

 Spikes solitary, 4 — 8 mm. long by 2 mm. broad; sporophylla of the upper
