base, dilated, auriculated, piloso-denticulate and somewhat imbricated over 

 the rachis on the upper side at the base; of the branchlets '2 as long; 

 leaves of the upper plane much smaller, erected, parallel, straight, ovate, 

 long-cuspidate, minutely denticulate at the edge, keeled, cordate at the 

 base, distant on the main rachis, imbricated on the branchlets, 

 rounded to cordate at the base, the outer base distinctly produced. Spikes 

 12Vs — 25 mm. long, 2 — 3 mm. broad; sporophylla of the upper plane 

 similar to the lateral leaves but smaller, subacute, keeled, serrulate, 

 somewhat ascending; of the lower plane more ascending, subparallel, 

 ovate, acuminate to cuspidate, serrulate, keeled; macrospores whitish or 

 pale-yellow, densely and minutely verruculose; microspores pale, dirty- 

 yellow or -orange, verruculose with capitate or tuberculiform projections. — 

 A plant gathered by Dr. Koorders, which is probably a form of this 

 species, differs in having the lateral leaves rounded or rotundate-cuneate 

 (not auriculate) on the upper side and somewhat dilated on the lower 

 side at the base, the spikes single or double, the macrospores more or 

 less deciduously verruculose.

Shoots erect, or ascending from a decumbent or ascending base. 

 Lateral leaves dilated, rotundate-cuneate, broadly rounded or subcordate 

 on the upper side at the base, cordate-truncate and not rarely subauriculate 

 on the lower side, those of the ultimate branchlets contiguous or rather 

 remote, more or less ascending; leaves of the upper plane acute to 

 acuminate. Spikes single or double, 1—4 cm. long, Vk — 2 mm. broad, 

 distinctly platystichous in the broadest, nearly square in the narrowest 

 forms. — Otherwise like S. fimbriata Spring. 



Var. polyura: Differs from the type in having the branches 

 narrower, the ultimate branchlets at best 3 mm. broad, tTie lateral leaves 

 smaller, more or less approximate on the main rachis, not rarely sub- 

 imbricate on the branchlets, the spikes narrower, 1—1 'A ram. broad, 

 sometfmes forked at the apex.
