Shoots erect or ascending from a more or less trailing base, densely 

 caespitose, to 10 cm. long, the stem compressed, sulcate above, convex 

 beneath, at best Vs mm. thick, stramineous, .the lower part simple or 

 dichotomous, the higher part pinnate ; pinnae simple or forked, or the lower 

 dichotomous. Leaves heteromorphous, very remote on both stem and 

 branches, pale-green, very thin; lateral leaves more or less horizontal, 

 equal-sided, suboblong-ovate, subobtuse, upper base rounded, lower base 

 rather rotundate-truncate, upper edge sparingly piloso-denticulate towards 

 the apex, shortly and slightly ciliate towards the base, lower edge 

 piloso-serrulate towards the apex, often entire towards the base, largest 

 leaves under 2 mm. long, under 1 mm. broad; intermedial leaves equi- 

 lateral, lanceolate-ovate, acutely acuminate but not cuspidate, outer base 

 cuneate, somewhat decurrent, inner base rounded, edges piloso-denticulate, 

 largest leaves hardly 1 mm. long, under Vs mm. broad. Spikes hardly 

 more than SVs mm. long, to 2V2 mm. broad; sporophylla very hetero- 

 morphous; of the upper plane more or less contiguous, subspreading, 

 very unequal-sided, keeled, obtuse, lower side sparingly, shortly serrulate, 

 upper side sparingly piloso-denticulate, ciliolate towards the base, the largest 

 2 mm. long, under V2 mm. broad; of the lower plane deltoid-ovate, 

 acuminate, ciliate on both sides, the largest under 1 mm. long, Vj mm. 

 broad; macrospores bright-yellow or orange-coloured, smooth, or irregularly
