the lower part, 20 30 cm. long, the stem 3-stelical, irregularly angular 

 and grooved when dry, provided with large, subcordate-oblong axillary 

 leaves; pinnae elongate-lanceolate, to 15 cm. long, to 3 cm. broad, 

 acuminate, spreading, the higher often ascending, the lower sometimes 

 deflexed; pinnulae simple, erecto-patent, contiguous or approximate, the 

 largest 2 3 cm. long, 57 mm. broad including the lateral leaves. 

 Leaves heteromorphous; leaves of the lower plane spaced on the stem, 

 crowded on the branchlets; of the stem horizontal, subpetiolate, oblong, 

 unequal-sided, 4 5 mm. long, 2 mm. broad, acute, entire, broadest on 

 the upper side, rotundate-cuneate on the upper base, rotundate-truncate 

 on the lower base; of the branchlets spreading, less unequal-sided, to 3 4 

 mm. long and I 1 /* 2 mm. broad, minutely apiculate-acuminate, more 

 suddenly cuneate on the lower base, narrowly pellucid-margined on the 

 upper 1 side; leaves of the upper plane erect; of the stem remote, falcate- 

 ovate, acute or acuminate, to 3 mm. long, entire, cuneate or rotundate- 

 cuneate on the inner base, cuneate or rounded to cordate on the outer base ; 

 of the branchlets smaller, imbricate, cuspidate-acuminate, the cusp V as 

 long as the blade, both sides more or less narrowly pellucid-margined. 

 Spikes solitary, square, t 4 cm. long, 1V 3 mm. diam.; sporophylla 

 isomorphous, lax, suberect, at length often spreading, triangular-oblong, 

 acute or acuminate, entire, keeled, narrowly pellucid-margined, to 2 mm. 

 long; macrospores yellow-brown, partly verrucose, partly rugose, the 

 projections free or connected; microspores whitish or yellowish, provided 

 with thick, crowded, tuberculate or shortly stipitate-capitate projections 

 on the basal side. 



War. retroflexa: Leaves of the lower part of the stem retro- 

 flexed; leaves of the rachis more crowded, spreading or retroflexed; inier-
