interrupted, and the upper side subentire towards the less blunt apex 

 and ciliolate-denticulate towards the base, the leaves of the upper plane 

 with the cusp longer, V* as long as the blade, the sporophylla elongate-

 which are whether not thickened at the apex.

Shoots trailing, repeatedly dichotomous, the rachis of the primary 

 branches 10 mm. broad including the lateral leaves, the ultimate branchlets 

 5 mm. broad. Lateral leaves rather close; of the stem horizontal or 

 nearly so, unequal-sided, obliquely falcate-oblong, bluntish or subacute, 

 the upper side papilloso-denticulate, ciliolate at or towards the broadly 

 rounded base, the lower side obsoletely denticulate towards the apex, 

 ciliolate at the truncate-rotundate base, the midrib thickened towards the 

 apex, the largest leaves 5 — 5 'A mm. long and 2 mm. broad; of the 

 branchlets similar, subspreading, more rotundate-cuneate at the minutely 

 denticulate lower base, the largest leaves 3 — 314 mm. long; leaves of the 

 upper plane obliquely subfalcate-ovate, unequal-sided, cuspidate, minutely 

 ciliolate-denticulate on both sides ; of the stem 3 mm. long, with the inner 

 base narrowly rotundate-cordate, the outer base more broadly so and 

 more produced, the cusp V3 as long as the blade; of the branchlets 

 similar but smaller, more rounded on the inner side at the base. Spikes 

 solitary or double, 1 cm. more or less long, VU — VU mm. diam. ; 

 sporophylla subisomorphous, equal-sided, deltoid, shortly aristate-acuminate, 

 keeled, minutely denticulate, the ventral ones the largest, IV2 mm. long; 

 macrospores mostly 2 (never 4) in a macrosporangium, white, rugulose 

 with flexuose, branched or reticulate rumples, the apex without radiating 

 ribs, encircled by a lacerate-denticulate crown-like crest ; microspores pale- 

 yellow, sparingly provided with capitate projections on the basal side.

Shoots traiUng, 15 cm. long, the stem 2-sulcate down the face, 

 copiously pinnately branched; branches approximate, little compound. 

 Leaves of the lower plane close on both stem and branches, oblong- 

 lanceolate, 3 — 4 mm. long and 1 — 2 mm. broad, horizontal or rather 

 ascending, dark above, pale beneath, bluntish, spuriously veined, moderately
