cate, acute or acuminate, minutely denticulate, pellucid- or pale-margined, 

 the largest 2 'A — 3 mm. long; macrospores yellowish-white, strongly 

 regulose, the projections free, flexuose, branched or reticulate, the apical 

 ribs encircled by a ring-shaped crest; microspores dirty-yellow or pale-

(11) S. remotifolia, Spring, PI. Jungh., 276; S. invohicrcUa, 

 Warb., Mons., I, 113. 



Shoots wide-trailing, or ascending towards the apex, pinnate, the 

 main stem (rachis) 1 — I'A mm. thick, stramineous, irregularly angled or 

 grooved when dry, 7 — 8 mm. broad including the lateral leaves; pinnae 

 remote, oblique, to 10 cm. long, or longer and growing out to new shoots, 

 the longest 2 — 3-pinnate; branchlets to 1 cm. long or longer, 3 — 5 mm. 

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

 approximate to imbricate on the branchlets ; of the stem horizontal or 

 subdeflexed, obliquely ovate, bluntish, the upper side very minutely 

 denticulate, broadly rounded at the base, the lower side very minutely 

 denticulate in the upper part, entire towards the more narrowly rounded 

 or rotundate-subtruncate base, the largest leaves 3 — 3'/j mm. long by 2 

 mm. broad; of the branchlets nearly similar but rather elongate-oblong, 

 less unequal-sided, submucronulate, rotundate-cuneate at the base, the 

 largest leaves 2V2 mm. long by 1 mm. broad; intermedial leaves erect; 

 of the stem remote, ovate, rather acuminate, slightly keeled, the inner 

 side more or less obscurely denticulate, rotundate or rotundate-subcordate 

 at the base, the outer side subentire, much produced and auriculate- 

 cordate at the base, the largest leaves SVa mm. long; of the branchlets 

 rather imbricate, smaller, the inner side more distinctly denticulate, 

 rotundate-cuneate at the base. Spikes short, square, 1 — Vz mm. diam.^ 

 with a few sterile bracts at the base, bearing a single macrosporangium 

 and several microsporangia ; lower sporophylla largest, to 3 mm. long, 

 ovate-lanceolate, denticulate, higher smaller, hardly 1 ''2 mm. long, lanceolate, 

 acute, keeled, minutely denticulate; macrospores rather large, reticulate, 

 the apical ribs encircled by a ring-shaped crest; microspores provided 

 with scattered or closely seriated, deciduous or persistent, tuberculiform 

 or subglobose projections on the basal side.
