 or incurved, spur-like; leaves of the branchlets similar; of the lower plane 

 3 mm. long, narrowly rotundate-curvate at the upper base; of the upper

 mm. long, square, 2 mm. diam.; sporophylla lanceolate, acuminate, den-

Shoots 30 40 cm. long, the lower part simple, tetragonal, IVz 2 

 mm. thick at the base, the upper part decompound, ovate in outline, 

 sometimes 2-partite at the base with the fork-branches similarly decom- 

 pound; pinnae lanceolate, ovate or obovate in outline; lower pinnulae 

 pinnate, with the lower branches simple or forked and the central one or 

 more times forked. Leaves of the stipe and lower part of the main rachis 

 isomorphous, equilateral, triangular, cordate at the base, acute or acuminate, 

 keeled, denticulate on both sides, ciliate at the base; leaves of the bran- 

 ches and the upper part of the main rachis heteromorphous; lateral leaves 

 ascending, obliquely falcate-ovate, subacute, spuriously nerved, denticulate 

 on the upper side which is ciliolated at the rotundate-cuneate base, entire 

 on the lower edge which is provided with 2 ciliae at the rotundate- 

 truncate or cordate-truncate base; of the main rachis the largest, rather 

 remote, to 2V 4 mm. long, to 1 mm. broad; of the ultimate branchlets 

 close, to 1 mm. long and V 2 mm. broad; intermedial leaves erect, ovate, 

 shortly acuminate, pellucid-dotted; of the principal rachises minutely den- 

 ticulate on both sides, sparingly ciliate at the obliquely cordate base, the 

 largest leaves 1Y mm. long and 3 < mm. broad; of the branchlets smaller, 

 obliquely rotundate-cuneate at the base, rather entire. Spikes solitary, 

 V 1 cm. long, 1 mm. diam.; sporophylla nearly isomorphous, subdeltoid- 

 ovate, shortly acuminate, nearly keeled, copiously denticulate on both 

 sides, the ventral ones somewhat larger, the largest hardly 1 mm. long; 

 macrospores yellowish or yellowish-white, rugulose, the rumples often 

 flexuose, ramose or reticulate; microspores orange or yellowish, sparingly 

 provided with short-stalked, capitate projections on the basal side.
