rotunda te-cuneate at the base; intermedial leaves 'A as long, oval, acute, 

 shortly apiculate, hardly falcate, pale-margined, minutely denticulate, 

 somewhat keeled, adnate and more or less rotundate-cuneate at the 

 base. — The destcription is compared with a sterile specimen of Cuming's 

 No. 1999 occurring in the Buitenzorg Herbarium; it agrees exactly 

 with a fertile specimen of Elmer's No. 9273. The said specimenis have 

 the shoots small, under 7 cm. long, the lateral leaves pellucid-m&rgined 

 on both sides, with the upper side ciliate or ciliolate in the lower half, 

 rounded at the base, the spikes platystichous, resupinate, to IV2 cm. 

 long, IV2 — 2 mm. broad at the base, the sporophylla of the upper plane 

 spreading, elongate-oblong, bluntish, keeled, the keel ciliolate, the upper 

 side remotely denticulate, remotely ciliolate towards the base, the sporo- 

 phylla of the lower plane erect, triangular-ovate, acuminate, remotely 

 ciliate, the macrospores yellow or pale-ochraceous, smooth, opaque, the 

 microspores yellow or minium-red, smooth.

(146) S. Zahnii, Micron., in Engl. Bot. Jahrb., L, 37. 



Shoots suberect from a creeping or subascending base, branched frbm 

 the base, the stem stramineous, distinctly 2-sulcate down the face, the 

 main rachis 4 mm. broad including the lateral leaves; lower and central 

 pinnae to 2V2 cm. long; pinnulae simple7 to 1 cm. long, the lower 

 rarely forked; ultimate branchlets 2 mm. broad.' Lateral leaves somewhat 

 remote on the main rachis, approximate or close on the branchlets; of 

 the main rachis subhorizontal, obliquely triangular-ovate, bluntish or sub- 

 acute, the upper side rounded, sparingly and very minutely denticulate 

 in the upper part, sparingly and gradually ciliolate towards the broadly 

 rounded base, narrowly pellucid-margined in the lower part, the lower 

 side nearly straight, sparingly and very minutely denticulate towards the 

 apex, subentire towards the narrowly rotundate-subtruncate base, the 

 largest leaves 3 mm. long by VU mm. broad; of the branchlets smaller, 

 spreading, unequally rotundate-cuneate at the base, the largest Vk mm. 

 long; intermedial leaves erect; of the main rachis ovate-lanceolate, nearly 

 straight, narrowly long-acuminate, subaristate, obliquely rounded at the 

 base, narrowly pellucid-margined, sparingly and very minutely denticulate, 

 the outer base somewhat produced, the inner base sparingly ciliolate, the 

 largest leaves 2 mm. long; of the branchlets smaller, proportionally 

 narrower, more lanceolate. Spikes terminal and solitary, 4 — 7 mm. long.
