stramineous, nearly 1 mm. thick; pinnae more or less copious, ascending 

 or suberect, the lower simply pinnate or rarely 2-pinnate; branchlets 

 erecto-patent or suberect, the lower to 2 cm. long, 2 — 3 mm. broad 

 including the lateral leaves. Leaves thin, heteromorphous; leaves of the 

 lower plane spreading or ascending; of the stem remote, unequal-sided, 

 oblique-oblong, the largest 2 — 2'/2 mm. long and 'k as broad, very minutely 

 denticulate on both sides or subentire on the lower side, ciliate on the 

 upper side in the lower half or towards the base, the upper base broadly 

 rounded, the lower base more narrowly so; of the branchlets similar, smaller, 

 IVj mm. long, relatively narrower, less unequal-sided, more acute, less 

 remote, less rounded at the base; leaves of the upper plane erect, 

 contiguous or imbricate; of the stem obovate, to 2 mm. long, cuspidate, 

 keeled in the upper part, minutely denticulate on both sides or rather 

 entire on the outer side, more or less ciliate at the base, the base 

 obliquely cordate, produced on the outer side, the cusp Vi as long as the 

 blade; of the branchlets similar but smaller, more distinctly denticulate, 

 less ciliate, the inner base rotundate-cuneate, the cusp often relatively 

 longer. Spikes Vi — IV2 cm. long, 2^k — 3 mm. broad; sporophylla of the 

 upper plane lanceolate, acute, the lower the largest, spreading, to 2 mm. 

 long, the upper side denticulate, ciliate at the base, the keel ciliate; of 

 the lower plane erecto-patent or suberect, ovate, acuminate, ciliate, 

 keeled; macrospores yellowish-white, smooth; microspores minium-red or 

 yellowish, smooth.

 Near S. myosuroides Spi-ing, but the pinnae sometimes much elongated 



and always pinnate, the intermedial leaves of the stem rounded or 

 rotundate-cuneate at the inner base, subcalcarate-cordate at the outer 

 base, the spikes narrower, IVs — 2 mm. broad, the sporophylla of the 

 upper plane shorter, not ciliate at the upper base, the macrospores 

 probably greyish-white and smooth or nearly smooth, the microspores 

 smooth or sparingly punctulate.
