Shoots 40 cm. long, the lower part simple, stramineous-green, com- 

 presso-quadrangular, to 3 mm. thick, the upper part pinnately compound, 

 deltoid-ovate in outline; pinnulae with their branches simple or forked. 

 Leaves heteromorphous ; lateral leaves of the stipe unequal-sided, the 

 lowest suberect, the following spreading, remote, broadly oblique-ovate, 

 subfalcate, shortly acuminate, with the upper side minutely denticulate, 

 obsoletely denticulate towards the apex, ciliate at the subauriculate- 

 cordate base, the lower side subentire, obsoletely denticulate towards the 

 apex, ciliate at the subtruncate-rotundate base, the largest leaves 4 mm. 

 long and 3 mm. broad ; of the main rachis glaucous-green, falcate-ovate, 

 acuminate, sparingly spuriously nerved, with the upper side piloso-den- 

 ticulate, narrowly pellucid-margined in the lower half, sparingly ciliolate 

 at the subauriculate-cordate base, the lower side entire, or hardly den- 

 ticulate towards the apex, sparingly ciliate at the truncate-rotundate 

 base, the largest leaves 6 mm. long and 3 mm. broad ; of the branchlets 

 similar but smaller, contiguous, ovate-oblong, lYi 3 mm. long and Y 1 

 mm. broad, obtuse, more distinctly pellucid-margined and spuriously 

 veined, the upper side cuneate in the lower half, very narrowly truncate-

 inner base subtruncate-rotundate, the largest leaves 3Y mm. long; of the 

 branches similar to those of the stipe but growing gradually shorter; of 

 the branchlets imbricate, very sparingly ciliolate and rotundate-cordate 

 on the produced outer side at the base. Spikes solitary, 5 15 mm.
