Shoots erect, or ascending from a decumbent base, 15 — 30 cm. long, 

 the stem subterete or obtusely angular, the branching between dichotomous 

 and pinnately decompound; principal rachises 6 — 10 mm. broad including 

 the lateral leaves; ultimate branchlets 2 — 5 mm. broad. Leaves hetero- 

 morphous; lateral leaves rather spaced on the main stem, mojre crowded 

 on the branchlets; of ths stem horizontal or spreading, 3 — 5 mm. long, 

 bluntish or mucronulate, spuriously veined and pellucid-margined, the 

 upper edge entire or obscurely denticulate towards the apex, gradually 

 ciliolate or ciliate towards the much produced auriculate-cordate base, 

 the lower edge entire, or minutely denticulate towards the rather narrowly 

 rounded or rotundate-cuneate base, the upper surface provided with a few 

 short, spine-like, scattered hairs near the lower edge; of the branchlets 

 smaller, I'A — 2 'A mm. long, acute, less spreading, obliquely rounded or 

 rotundate-cuneate at the base; intermedial leaves small, roundish, oblong, 

 ovate or obovate, denticulate or ciliate, narrowly pellucid-margined, long- 

 cuspidate, the cusp as long as the blade ; of the stem abruptly cuspidate, 

 obliquely cordate at the base, the outer base produced; of the branchlets 

 acuminate-cuspidate, obliquely rounded or rotundate-cuneate at the base. 

 Spikes copious, square, 6 — 12Vj mm. long and 2 mm. diam. ; sporophylla 

 ovate, acuminate, denticulate-ciliolato, rather pellucid-margined, keeled ; 

 macrospores irregularly rugulose or reticulate, or verruculose, and the 

 apical ribs encircled by a ring-shaped crest; microspores whitish or 

 yellowish, provided with capitate or bacilliform projections on the basal side. 



Forma typica: Ciliae short, rather oblique.
