margined, rounded or subcordate at the base, those of the stem the 

 largest ; leaves of the upper plane Vs as long, oblique-oblong, erect, entire, 

 shortly acuminate to cuspidate, pellucid-margined, subcordate at the base, 

 the outer base hardly produced. Spikes square, 6 12V mm. long, 2 1 /, 

 mm. diam. ; sporophylla crowded, ascending, ovate-lanceolate, 2V mm. 

 long, keeled; macrospores yellowish- white, irregularly verruculose with 

 free or connected tuberculiform projections; microspores provided with 

 minute crest-like projections on the basel side and encricled by an equa- 

 torial belt consisting of spiniform or dilated, truncated, bacilliform pro-

(9) S. alopecuroides, Ufc., Fern All., 77. 



Shoots ascending, above 30 cm. long, with several ascending, simple 

 or 2 3-furcate branches. Leaves of the lower plane crowded, oblique- 

 lanceolate, 8 10 mm. long, produced on the upper side at the base, 

 with a large cordate auricle imbricated over the rachis, moderately firm 

 in texture, bright-green, not ciliated ; leaves of the upper plane ovate, 

 ascending, much imbricated, 3 3V mm. long, not cuspidate. Spikes 

 square, r/4 2Vi cm. long, 4 4 'A mm. diam., 2 3-nate from the tip of 

 the branches; sporophylla rigid, ovate, acuminate, erecto-patent, strongly 

 keeled. 



Specimens occurring in the Buitenzorg Herbarium are distinguished 

 by the following characters not mentioned in Baker's diagnosis: Shoots 

 ascending from a probably creeping base, pinnate quite to the base; 

 pinnae to 20 or rarely to 30 cm. long, simple, forked, dichotomous or 

 slightly pinnate, the lowest pinnae whether or not elongated, rooting and 

 growing out to new shoots; main and secondary rachises terete or obtusely 

 quadrangular. Leaves of the lower plane horizontal or subspreading, 

 falcate, sublinear, rather bluntish, spuriously nerved, pale-glittering beneath, 

 with the upper side pellucid-margined, entire, obsoletely denticulate at 

 the broadly rotundate-subcordate or rotundate-cuneate base, the lower 

 side entire except towards the very minutely denticulate apex; leaves of 

 the upper plane 3 5 mm. long, more or less acuminate, pellucid-margined, 

 minutely denticulate, rotundate-cuneate at the base, those of the main 

 rachis not or hardly imbricate. Spikes 16 cm. long, 3 4V mm. diam.; 

 sporophylla ovate-subulate, pellucid-margined, minutely serrulate; macro- 

 spores yellowish-white, rather coarsely rugose with flexuose, branched
