rotundate-cuneate at the base, the largest leaves 2 mm. long by 3 A 1 

 mm. broad; of the branchlets similar but more ascending, smaller, more 

 narrowed at the base; intermedial leaves erect, oblique-ovate, acutely 

 subcuspidate-acuminate, narrowly pellucid-margined and more or less 

 sparingly serrulate on both sides, the outer base narrowly rounded, the 

 inner base rotundate-cuneate; of the stem the largest, 1V4 mm. long. 

 Spikes solitary, terminal, or apparently lateral (on rudimentary branchlets), 

 4 7 mm. long, 1V 2 mm. broad; sporophylla of the upper plane oblique- 

 ovate, to r/4 mm. long, acute, keeled, the upper side rather pellucid- 

 margined, remotely ciliolate; of the lower plane suberect, deltoid-ovate, 

 acuminate, remotely ciliate; macrospores ivory-white or yellowish-white, 

 opaque, very minutely granulate; microspores red or saffrony, smooth. 

 Negros.

Shoots erect, or ascending from a short-creeping base, 5 15 cm. 

 long, r/2 3Y cm. broad, the lower part simple (stipitiform) or sparingly 

 branched, the upper part 2-pinnate, the stem subcompresso-terete, 1Y mm. 

 thick, stramineous-green or pale-yellow-brown, when dry more or less 

 distinctly grooved down the upper side, 2V 2 mm. broad including the 

 lateral leaves; pinnae sparingly pinnate; ultimate branchlets iVa mm. 

 broad. Leaves heteromorphous ; lateral leaves remote on the stem, 

 contiguous or approximate on the branchlets; of the stem subspreading, 

 oblong, nearly equal-sided, subacuminate, the upper side minutely serrulate 

 towards the apex, otherwise deciduously ciliate, broadly rounded at the 

 base, the lower side entire or very minutely or indistinctly serrulate, 

 provided with 2 very short ciliae at the rotundate-cuneate base, the 

 largest leaves 1 Vz mm. long by about Y* as broad ; of the branchlets more 

 oblique, smaller, nearly equally rotundate-cuneate on both sides at the 

 base; intermedial leaves erect; of the stem rather remote, ovate, acuminate, 

 very minutely or indistinctly serrulate towards the apex, the outer side 

 minutely serrulate, provided with 2 very short ciliae at the produced, 

 narrowly rotundate-truncate and subauriculate base, the inner side remotely 

 deciduously ciliate, rotundate-cuneate at the base, the largest leaves 1Y* 

 mm. long; of the branchlets imbricate, smaller, sparingly ciliate and 

 serrulate, obliquely subrotundate-cuneate at the base. Spikes solitary, 

 3 7 mm. long, 1 mm. broad; sporophylla of the upper plane oblique, 

 obliquely and shortly deltoid-oblong, acute, keeled, to 1 mm. long, the upper
