acuminate, very narrowly pellucid-margined; of the secundary rachises 

 rather remote, horizontal, with the upper base rounded, the lower base 

 rotundate-truncate ; of the pinnulae approximate, subhorizontal, the higher 

 more ascending, the largest 6 — 6'/i mm. long, to 2'/, mm. broad, with 

 the upper base hardly plicate, rotundate-cuneate, the lower base rotundate 

 or rotundate-truncate; intermedial leaves erect, unequal-sided, falcate- 

 ovate, very narrowly pellucid-margined ; of the secondary rachises obliquely 

 adnate and narrowed on both sides at the base (the outer base produced, 

 rather decurrent-cuneate), the lower acutely acuminate, the higher gradually 

 cuspidate ; of the pinnulae subabruptly cuspidate, to 4 mm. long, with 

 the cusp '/s — Va ^s loi^S' ^-s the blade, the outer base cordate or rounded, 

 produced. Spikes terminal, solitary or 2 — 3-nate, normally 1 — I'/j mm. 

 diam., sessile or pedunculate, the stalk to + 1 cm. long, provided with 

 lax, erected, ovate, acute or acuminate, entire, sterile bracts; sporophylla 

 broadly ovate, to 1 mm. long, acuminate, entire, very narrowly pellucid- 

 margined, keeled, erect or finally spreading ; macrospores whitish, densely 

 and finely verruculose; microspores whitish, provided with densely crowded, 

 sessile or short-stalked capitate pi^ojections. — The true systematical 

 place of this species is uncertain, the description being founded on an 

 incomplete specimen.

Shoots erect, or ascending from a creeping base, 25 — 45 cm. long, 

 pinnate throughout, or the lower part simple, or forked with pinnated 

 secondary shoots, the stem 2 mm. thick, 3-stelical, stramineous and 

 irregularly grooved when dry, with the lower axillary leaves short-oblong, 

 or broad-ovate, acuminate, broadest at or below the middle; pinnae 

 remote, subovate in outline ; lower pinnulae pinnate, higher simple ; ultim- 

 ate branchlets few, remote, to 1 '/^ cm. long, the lower part 3 mm. 

 broad including the lateral leaves. Leaves heteromorphous ; leaves of 

 the stem very remote, subsimilar to those of the secondary rachises but 

 less oblique; leaves of the branches pellucid-margined; lateral leaves 

 spreading or more ascending, subfalcate-oblong, entire or subentire towards 

 the base, shortly and remotely denticulate towards the mucronulate-
