(105) S. Hellwigii, nieron., in Engl. Bot. Jahrb., L, 12. 



Shoots erect from an ascending base, 15 — 30 cm. long, the lower 

 part simple, compressed, dirty-stramineous-brown, like the rachises minutely 

 pubescent on the back, when dry 3-sulcate, to 2 mm. thick, sparingly 

 leafy, the upper part 4-pinnate, ovate or rotundate-ovato, to 20 cm. each 

 way, the main rachis 3 — 4 mm. broad including the lateral leaves; pinnae 

 rather close, ovate, to 12 cm. long, with closely placed pinnulae; ultimate 

 branchlets 1 mm. broad. Leaves heteromorphous; lateral leaves of the 

 stipe erect, remote, triangular-ovate, unequal-sided, broadest on the inner 

 side, acute, narrowly 2-auriculate-cordate at the base, obsoletely denticulate 

 on both sides, the largest leaves to 4 mm. long and Vk mm. broad; 

 intermedial leaves of the stipe ovate-oblong, long-acuminate, slightly 

 keeled, obsoletely or very minutely denticulate, unequal-sided at the base, 

 the inner base shortly cordate, the outer base produced, auriculate-cordate, 

 the auricles hamato-incurvate, the largest leaves 3 mm. long and 1 mm. 

 broad; lateral leaves of the main rachis suboblique-ovate, acute, nearly 

 equal-sided, the upper side minutely denticulate but obsoletely so towards 

 the apex, partly pellucid-margined, subcordate-rotundate at the base, the 

 lower side obsoletely denticulate towards the apex, minutely denticulate 

 at the truncate-auriculate base, the largest leaves SVs mm. long and VU 

 mm. broad; intermedial leaves of the main rachis ovate-oblong, shortly 

 aristulate-acuminate, somewhat denticulate in the upper part, the inner 

 base rounded, the outer base produced, the auricle slightly incurved, 

 rounded or subtruncate, the largest leaves 2 mm. long and 1 mm. broad; 

 leaves of the branchlets subsimilar but smaller, bluntish, the lateral ones 

 to V4 mm. long, obliquely rotundate-truncate at the base, the intermedial 

 ones often quite entire, acute, the inner base narrowly rotundate-cuneate, 

 the outer base rotundate-subcordate. Spikes solitary, short, nearly 2 mm. 

 diam.; sporophylla ovate, to VU mm. long, the longest the narrowest, 

 aristulate-acuminate, keeled, minutely denticulate; macrospores yellow-
