middle, minutely serrulate and narrowly pellucid-margined in the lower 

 part, rather broadly rounded at the base, the lower side entire in the 

 lower part, rotundate-cuneate or narrowly truncate-rotundate at the base, 

 the largest leaves 3V2 mm. long by I'A ram. broad; of branchlets similar 

 but more narrowed at the base, to 2 mm. long by 'A as broad; inter- 

 medial leaves erect, black-green, obliquely ovate, nearly straight, aristate- 

 acuminate, minutely serrulate, narrowly pellucid-margined, the outer base 

 produced, auricled, the auricle rounded, the inner base rotundate, the 

 largest leaves 2V4 mm. long, the cusp about V* — 'A as long as the blade. 

 Spikes solitary or double, terminal, or apparently lateral (on rudimentary 

 branchlets), 5—15 mm. long, IV2 — 2 mm. diam.; sporophylla deltoid-ovate, 

 shortly acuminate, keeled, minutely serrulate, subpellucid-margined, the 

 largest VU mm. long; macrospores whitish, stramineous- white or black, 

 with minute, rugiform, flexuose or branched ridges, the apical ribs encircled 

 by a slightly elevated ring-shaped crest; microspores yellowish-white or

Shoots springing from a high-scandent main shoot, 3 — 4-pinnate, the 

 stem compressed, pale-ochraceous or ochraceous-green, IV2 mm. thick, 

 often slightly grooved when dry; pinnae ascending, remote, the rachis 

 7 — 10 mm. broad including the lateral leaves; ultimate branchlets 4 — 5 

 mm. broad. Leaves heteromorphous; lateral leaves spreading; of the stem 

 remote, oblique-ovate, obtuse, very minutely serrulate on both sides, the 

 upper side gradually ciliolate at the rounded base, the lower side often 

 ciliolate at the narrowly rounded base, the largest leaves 4V2 mm. long, 

 2V2 — 274 mm. broad; of the branches nearly similar, approximate to 

 imbricate, often provided with interrupted spurious veinlets, the upper 

 side pellucid-margined, ciliate at the base, the lower side entire except 

 towards the obscurely serrulate apex, ciliate at the base, the ciliae 

 continued upon the rachises; of the principal rachises 5 mm. long by 2
