cuspidate. Spikes short, S'A mm. broad; sporophylla of the upper plane 

 lanceolate, acuminate, rigidly erecto-patent; of the lower plane paler, 

 rather shorter, more ascending; macrospores reddish-white to brown, with 

 conical or torulose projections on the basal side; microspore^ minium-red, 

 with crowded' conical projections on the lower side.

(164) S. d'itrmandvillci, v. A. «. n.. Bull. Btz., 1911, I, 23; 

 1914, XVI, 50; — var. busuensis, v. A. v. R., 1914, 1. c. 



Shoots ascending, 15 — 40 cm. long, linear or linear-lanceolate in 

 outline, pinnate, the stem stramineous when dry, subterete, to V-2 mm. 

 thick; pinnae suberect, I'A — 3 cm. broad, distant, the higher simple or 

 forked, the lower IV2 — 3 cm. long, pinnate; pinnulae with a few simple or 

 once or twice forked branchlets; ultimate branchlets 2 — 6 mm. long, 

 2 — 3 mm. broad including the lateral leaves. Leaves heteromorphous, very 

 distant on the stem, less so on the branchlets; leaves of the lower plane 

 horizontal or nearly so; of the stem oblong, 2 mm. long, 1 — I'A mm. 

 broad at the base, very blunt at the apex, the upper edge minutely den- 

 ticulate, rather entire towards the apex, the lower edge entire or nearly so, 

 the upper base much dilated and broadly rounded, the lower base cuneate; 

 leaves of the upper plane ovate-acuminate, IV2 mm. long, unequal-sided, 

 broadest on the inner side, minutely denticulate, rounded at the base; 

 leaves of the branchlets similar but smaller; those of the lower plane 

 rather blunter, less dilated at the upper base, with the upper edge entire 

 towards the apex; those of the upper plane incurvate-falcate, rather 

 keeled. Spikes oblong, 3 — 15 mm. long, 2 — 3 mm. broad; sporophylla ot 

 the upper plane similar to the leaves of the lower plane but less blunt, 

 subacute, broadly keeled, the lower spreading, to 2 mm. long, not 

 imbricated, the higher more ascending; those of the lower plane ascending, 

 ovate-acuminate, equal-sided, to 1 '2 mm. long, minutely denticulate, 

 keeled; macrospores whitish, densely deciduously and minutely papilloso- 

 verruculose; microspores orange-coloured to whitish, apparently reticulated 

 by the densely crowded, sharply bounded, tuberculiform projections. 



Var. busuensis: Pinnae to 8 cm. long; ultimate branchlets 

 narrower, at best 2 mm. broad; leaves of the upper plane smaller, rather 

 straight; of the stem to 1 mm. long, broadly adnate and both sided 

 rotundate-cuneate at the base; spikes narrower, at best 2 mm. broad.
