minutely denticulate at the upper edge, slightly spuriously nerved, broadly 

 rotundate on the upper side at the base, subentire on the lower side 

 except at the hardly denticulate apex and the rotundate-truncate base, the 

 largest leaves 6V* mm. long and 3Vs mm. broad; of the branchlets similar 

 to those of the main rachis but smaller, more ascending, narrowed at 

 the base, the largest 2 3 mm. long and 3 A 1 mm. broad; intermedial 

 leaves erect; of the stipe obliquely subfalcate-ovate, unequal-sided, shortly 

 aristate-acuminate, more or less copiously minutely denticulate, produced 

 and incurvate-cordate on the outer side at the base, rotundate-subcordate 

 on the inner side at the base, the largest leaves 4 mm. long; of the 

 main rachis similar to those of the stipe ; of the branchlets similar but 

 smaller, subentire towards the base, sparingly denticulate towards the 

 apex, the outer base auriculate-cordate, the inner base narrowed. Spikes 

 solitary, 3 6 mm. long, 1 TA mm. diam. ; sporophylla subisomorphous, 

 deltoid-oblong, gradually aristate-acuminate, piloso-denticulate, keeled, hardly 

 pellucid-margined, the posterior ones the largest, to 2 mm. long; micro- 

 spores yellow or yellowish, provided with conical or clavate-capitate 



projections on the basal side; macrospores

Shoots erect, or erect from an ascending base, 15 25 cm. long, 

 3 4-pinnate, the stem subterete, brownish-stramineous, 1V mm. thick 

 at the base; pinnae to 10 cm. long; ultimate branchlets to 1 cm. long, 

 2 2V 2 mm. broad including the lateral leaves. Leaves heteromorphous ; 

 leaves of the lower plane erecto-patent; of the stem remote or approximate, 

 oblong, unequal-sided, 2Y a 3 mm. long, to 1V 2 mm. broad at the base, 

 blunt or bluntish, the upper- side minutely serrulate and pellucid-margined 

 in the lower half, rounded at the base, the lower side entire, very 

 narrowly rotundate-truncate at the base; of the ultimate branchlets 

 similar, more or less close, often entire, subfalcate, less unequal-sided, to 

 2 mm. long and V 2 as broad, rotundate-cuneate on the upper side at the 

 base ; leaves of the upper plane erect ; of the stem remote or approximate, 

 oblong, 3 mm. long, abruptly long-cuspidate, sparingly and very minutely 

 serrulate, obliquely cordate at the base, or the inner base rounded or 

 rotundate-cuneate and the outer base produced, incurvate-auriculate, the 

 cusp to nearly as long as the blade ; of the branchlets similar, smaller, 

 imbricate, more gradually cuspidate, entire, the inner base rotundate-
