Shoots decumbent, or ascending from a wide-trailing base, reaching 

 a length of 30 — 120 cm., the stem 3-stelical, when dry angular and sul- 

 cate; pinnae often 10—15 cm. long; pinnulae varying from simple to 

 copiously pinnate; ultimate branchlets erecto-patent, to SVt cm. long, 4 — 6 

 mm. broad including the lateral leaves. Leaves entire, heteromorphous; 

 lateral leaves remote on the stem, close on the branchlets; of the stem 

 oblong, acuminate, the upper side rounded, narrowed gradually at the 

 base, the lower side nearly straight, subcordate-rotundate at the base; 

 of the branchlets horizontal or spreading, lanceolate-oblong, 2 — 3 mm. 

 long, IV2 — 2 ram. broad, rather abruptly mucronulate-acuminate, narrowly 

 pellucid-margined, the upper side rotundate-cuneate at the base, the lower 

 side more or less truncate-rotundate and somewhat dilated at the base; 

 intermedial leaves erect; of the stem remote, oblong, nearly straight, 

 acuminate, obliquely rotundate-cordate at the base, the auricles more or 

 less rotundate-incurvate ; of the branchlets imbricate, subfalcate-ovate, 

 acuminate to cuspidate, pellucid-margined, very obliquely adnate and 

 narrowly cuneate at the base, the produced outer base decurrent or 

 somewhat rounded. Spikes 1 — 2 mm. diam. ; sporophylla ovate, acuminate, 

 entire, pellucid-margined. 



Forma typica: Pinnae broadly ovate or triangular-ovate; macrospores 

 brownish, albo-verruculose ; microspores more or less prickly. — Nicobares 

 to the Moluccas, Formosa and South China. 



Forma punctata: Pinnae elongate-oblong or lanceolate. — Cuming's 

 No. 1995 has the macrospores pale-brown, finely verruculose, the micro- 

 spores yellowish, with densely crowded clavate or stipitate-capitate pro- 

 jections. — Jagor's No. 905 (var. angustiramosa, Hieron., MS.), which 

 would be better treated as forma angustiramosa, has the macrospores 

 pale-yellow, finely verruculose, the projections punctiform or shortly rugi- 

 form, the microspores yellowish-white, with the projections tuberculiform 

 or clavate. — Mindoro. 



War. philippinensis: Macrospores black, somewhat glaucous, 

 black- verruculose. — Philippines. 



War. Iirevifolia: Lateral leaves smaller, oblong, to 2V2 mm. 

 long, to VU mm. broad, less abruptly acuminate, rather minutely
