Shoots procumbent, or ascending towards the apex, to 30 cm. long, 

 sparingly pinnate, or forked and pinnate, the stem rather unequally 

 quadrangular, concave on the face and sides, or convex on the face, 

 convex on the back, regularly foliate, as are the branches ; pinnae erecto- 

 patent ; pinnulae erecto-patent, once or twice forked with short branchlets. 

 Leaves firm; leaves of the lower plane subhorizontal and somewhat 

 spaced on the stem, more ascending and close on the branchlets; of the 

 stem conspicuously unequal-sided, subfalcate-oblong, 4 — 5 mm. long, 'A as 

 broad at the base, acutate, the upper side more or less denticulate, or 

 entire at the centre, not rarely ciliolate to ciliate towards the broadly 

 rotundate-subcordate base, the lower side entire, or minutely denticulate 

 towards the apex, provided with — 6 ciliate at the rather narrow base; 

 of the branchlets nearly similar, smaller, IV2 — 3 mm. long, less unequal- 

 sided, more or less rounded on the upper side at the base; leaves of the 

 upper plane erect; of the stem rather spaced, 3 mm. more or less long, 

 suborbicular-oblong or broadly obovate, abruptly long-cuspidate, denticulate 

 or ciliolate, or ciliate at the base, nearly keeled, the cusp often more 

 than V2 as long as the blade, the outer base conspicuously produced with 

 the auricle rotundate to hamato-incurvate ; of the branchlets similar, 

 smaller, imbricate. Spikes square, 5 — 15 mm. long; sporophylla ovate, 

 acute or acuminate, keeled, minutely ciliolate-serrulate ; macrospores 

 whitish, 2 in a macrosporangium, more or less densely rugulose with 

 short or elongated, flexuose, branched or connected rumples on the basal 

 side, the apex flattened, without radiating ribs, encircled by a crown- 

 shaped crest; microspores probably wanting. 



Forma typica. — Western Malaya. 



'Wa.v. tumida: Leaves of the upper plane attached by a produced 

 or subpeltate tumefaction between the basal lobes; the outer base less 

 produced, rather truncate-subcordate. — Banca.

Shoots trailing, the lower part 10 mm. broad including the lateral 

 leaves, dichotomous, the upper part pinnate; pinnae to 7 mm. broad
