nearly so, bluntish or subacute, entire, more or less cuneate, rounded or 

 truncate at the base, somewhat dilated on the upper side near the base, 

 laterally affixed, the largest 4 mm. long, 2 2V mm. broad; those of the 

 ultimate branchlets nearly similar, crowded, more ascending, subequilateral, 

 with the upper base cuneate, the lower base adnate, rather decurrent, with 

 a small, rounded corner above the base, the largest leaves 2V mm. long, 

 1 1V mm. broad; leaves of the upper plane erect, rather parallel; those 

 of the principal rachises distant, triangular-falcate, incurved, long-acuminate 

 or cuspidate, entire, the largest 2 mm. long, with the inner base rounded 

 or truncate, the jouter base cuneate, long-decurrent; those of the ultimate 

 branchlets smaller, imbricated, obliquely ovate-lanceolate, long-cuspidate, 

 the cusp as long as the blade, the inner edge slightly rounded, the outer 

 conspicuously so, thB inner base rotundate-cuneate, the outer cuneate, 

 long-decurrent. Spikes often solitary, sometimes double, square, 5 mm. 

 more or less long, 1 mm. diam. ; sporophylla isomorphous, ovate, acuminate, 

 keeled, entire, erecto-patent, at length somewhat spreading; macrospores 

 whitish or yellowish, irregularly tuberculato- or conico-verrucose to sub- 

 rugulose, the projections of the basal side scattered, those of the apical 

 side crowded; microspores yellowish or whitish, tuberculato- or capitato- 

 verruculose to subrugulose. The description is taken from a cultivated

Shoots erect or ascending from a creeping, subterraneous, lacerate- 

 squamulose, 2-stelical rhizome, simple in the lower part, decompound in 

 the upper part, the branched portion deltoid or ovate in outline, with 

 the branches liable to curl up in drought, the stem obtusely quadrangular 

 at the base, stramineous, 1- or sub-2-stelical, more or less deciduously 

 pubescent like the main rachis beneath; pinnae more or less ascending 

 or subspreading, the higher simple or forked, the largest triangular, ovate 

 er lanceolate-oblong, 2 3-pinnate, the rachises pubescent beneath; ultimate 

 branchlets 24 mm. broad including the lateral leaves. Leaves of the 

 stipe and lower part of the main rachis isomorphous, erect, remote, oblong, 

 2Vi mm. long and 1 mm. broad, the apex shortly but sharply acuminate, 

 the edges parallel, entire, the base irregularly truncate, peltate; leaves
