nearly so and cuneato at the base ; of the upper plane ovate or oblong- 

 ovate, the largest 2 mm. long, V* mm. broad in the lower half, the outer 

 base produced, auriculate-cordate, the edges more or less sparingly den- 

 ticulate, the apex long-cuspidate, the cusp Vs — V2 as long as the blade. 

 Spikes 3 — 5 mm. long, 2 mm. diam. ; sporophylla slightly dimorphous, 

 subdeltoid, equal-sided, shortly aristate, piloso-denticulate ; those of the 

 lower plane nearly pale-green, the largest Vk mm. long, 'A mm. broad 

 near the base; of the upper plane somewhat darker, shorter and narrower; 

 macrospores nearly orange-coloured, slightly rugulose, the projections 

 whitish, sometimes reticulate, the apex without radiating ribs, encircled 

 by g, crown-like ring; microspores probably wanting.

(14) S. aciitangula, Sprina, Mon., II, 206; Bk., Fern All., 75. 

 Shoots procumbent, 15 cm. long, closely pinnate, the stem unequally 



quadrangular; pinnae ascending, copiously pinnate; pinnulae short, once 

 or twice forked. Leaves heteromorphous ; leaves of the lower plane rather 

 spaced on both stem and branches; of the stem spreading, moderately 

 firm, unequal-sided, rhomboidal-oblong, 2 — 2V2 mm. long and V2 as broad, 

 rather spuriously veined and somewhat pellucid-margined, the upper side 

 sparingly denticulate or even entire towards the apex, remotely ciliated 

 towards the rather rounded base, the lower side entire, narrowly truncate- 

 cuneate at the base; of the branchlets similar, subacute, less unequal- 

 sided, more rotundate-cuneate at the base, the largest Vln mm. long; 

 leaves of the upper plane 'A — V2 as long, broadly oblong, long-cuspidate, 

 rather pellucid-margined, sparingly denticulate towards the apex, remotely 

 ciliate towards the base, the outer base produced, cordate, the inner 

 base cordate or rotundate. Spikes copious, square, r/2— 2 mm. diam.; 

 sporophylla ovate, acute, keeled, denticulate, rather pellucid-margined. — 

 Probably identical with S. plumea Spring.
