Shoots more or -less decumbent to subascending, ascending towards 

 the apex, 15 — 30 cm. long, branched from the base, the stem 2-sulcate 

 down the face, flat on the back, the branching between pinnate and 

 dichotomous. Leaves of the lower plane close on both stem and branches 

 or somewhat spaced on the stem, spreading or rather ascending, rhomboid- 

 oblong, straight or subfalcate, 3V2 — 7V2 mm. long, IVi— 2V2 mm. broad, 

 those of the main stem the largest, more or less obtuse, dark-green above, 

 pale-glittering and spuriously veined beneath, unequal-sided, broadly rounded 

 or subcordate on the upper side at the base, very minutely denticulate 

 or subentire on the pale-margined upper side ; leaves of the upper plane 

 'A — V2 as long, oblong, ovate or obovate, minutely denticulate, rather 

 long-cuspidate, much imbricated, the inner base rounded or slightly cordate, 

 the outer base prominent, cordate, the cusp Vs — V2 as long as the blade. 

 Spikes square, 'A — 2V2 cm. long, 2 — 3 mm. diam.; sporophylla ascending, 

 or the lower subspreading, triangular-oblong, acuminate, entire or minutely 

 serrulate, distinctly keeled; macrospores 3 — 4 in a macrosporangium, 

 white, yellow or brown, irregularly verruculose, rugulose or somewhat 

 reticulate on the basal side, with 3 radiating ribs which are encircled by 

 by ring-shaped crest; microspores provided with bacilliform or stipitate-
