Shoots erect from the base or creeping in the lower part, 6 — 12 cm. 

 long, the flaccid, erecto-patent branches pinnate; ultimate branchlets 

 short, 2V2 — 3V2 mm. broad including the lateral leaves. Leaves thin; 

 lateral leaves much spaced and spreading or squarrose on the stem, 

 ascending and less remote on the branchlets ; of the stem rhomboid-oblong, 

 2V2 — 3 mm. long, I'A mm. broad, subacute or bluntish, membranous, 

 unequal-sided, much dilated and broadly rounded or subcordate on the 

 upper side at the base, narrowly rounded on the lower side, very minutely 

 serrulate, or entire at the base; of the branchlets smaller, 2 mm. long; 

 intermedial leaves rather equal-sided, small, ovate, long-acuminate-cuspidate, 

 narrowly pale-margined. Spikes to 9 mm. long, 2V2 — 3Vs mm. broad; 

 sporophylla of the upper plane spreading, lanceolate-oblong, acute, minutely 

 serrulate on both sides, keeled; of the lower plane suberect, ovate, 

 long-acuminate-cuspidato, serrulate, keeled; macrospores pale-reddish or 

 yellowish- white, finely punctulate-verruculose ; microspores minium-red or 

 orange, irregularly verruculose or rugulose-verruculose.

 Shoots ascending from a short-decumbent base, ovate in outline, 



branched down nearly to the base, 8 — 15 cm. long, the stem stramineous, 

 V2 — 1 mm. or more thick in the lower part; pinnae erecto-patent or sub- 

 spreading, the lower pinnate, little compound, the higher simple, the 

 largest to 6 cm. long; ultimate branchlets at best 1 cm. long, 3— 8V2 

 mm. broad including the lateral leaves. Leaves heteromorphous, thin- 

 membranaceous; lateral leaves very remote on the main stem, less so 

 on the branches, with the interstices at least as broad as the leaves, the 

 lower horizontal, the higher more ascending, ovate-oblong, blunt or bluntish, 

 minutely denticulate on both sides, broadly subcordate or rounded on the 

 upper 'side at the base; of the stem 2— 2V2 mm. long, of the branches
