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 Y mm. thick, stramineous, the lower part simple or 

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

 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 Va mm. broad. Spikes hardly 

 more than 3V mm. long, to 2V 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 Va mm. broad; of the lower plane deltoid-ovate, 

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