 Shoots more or less. decumbent to subascending, ascending towards 



the apex, 15 30 cm. long, branched from the base, the stem flattened, 

 2-sulcate on both sides, the branching between pinnate and dichotomous, 

 more or less erecto-patent to suberect, the ultimate branchlets 1 7 cm. 

 long, 5 7 mm. broad, the main rachis to 10 mm. broad including the 

 lateral leaves. Leaves dimorphous on both stem and branches; lateral 

 leaves horizontally spreading or nearly so, contiguous and imbricated on 

 the branches, slightly remote or contiguous on the stem, pale-glittering 

 beneath, oblong, bluntish or subacute, hardly falcate, rather straight, 

 hardly dilated near the base, the base rotundate-cordate on both sides, 

 or rotundate-truncate on the lower side, the upper edge minutely den- 

 ticulate throughout, the lower edge entire but indistinctly denticulate 

 towards the apex and the base ; of the stem 4 5 mm. long, to 2 mm. 

 broad; of the ultimate branchlets 2Yz 3Vz mm. long, 1 I 1 4 mm. broad 

 near the base; intermedial leaves erected, imbricate, oblong-ovate or 

 -obovate, to 2 mm. long, unequal-sided, rather suddenly acuminate or 

 shortly cuspidate at the apex, minutely denticulate on both sides, the 

 base oblique, narrowly rounded or retundate-cuneate on the inner side, 

 produced and auriculate-cordate, slightly hamato-incurvate on the outer 

 side. Spikes single or double, terminal or axillar, to 1V 2 cm. long, sub- 

 quadrangular, 2 mm. diam. ; sporophylla isomorphous, ovate, acute, keeled, 

 minutely denticulate, erecto-patent, those of the lower plane somewhat 

 larger, I 1 4 mm. long, the lower finally somewhat spreading; macrospores 

 yellowish-white, verruculose-rugulose, the projections free, branched or 

 connected, the apical ribs encircled by a ring-like crest; microspores dirty-

Shoots decumbent, 30 cm. long, sometimes forked in the lower part, 

 the upper part pinnately compound, the main rachis 5Vz mm. broad 

 including the lateral leaves; ultimate branchlets 3V 4 mm. broad. Leaves 

 of the lower plane very unequal-sided, oblong, the largest 2Vi mm. long, 

 hardly V/t mm. broad near the base, subfalcate, subobtuse or subacute, 

 rather dark-green, minutely denticulate on both sides towards the apex, 

 the upper side the broadest, subspinuloso-ciliate in the lower half, much
