Shoots erect from a creeping base, 15—35 cm. long, the base simple, 

 compressed, subquadrangular, bright-yellow, glossy, to 1 mm. or more 

 thick, the upper part pinnately compound, ovate-lanceolate in outline; 

 lower pinnae. 3-pinnate at the base, central 2-pinnate at the base, higher 

 simply pinnate; branchlets simple or forked. Leaves of the lower part 

 of the stipe isomorphous, more or less decussate, bracteiform, those of the 

 main rachis and branches heteromorphous, bright-green, rigid ; leaves of the 

 lower plane spaced even on the branchlets; of the main rachis very 

 unequal-sided, oblique, ovate, acute, rounded on the upper side, shortly 

 truncate or auricled on the lower side at the base, pellucid-margined on 

 the upper side, piloso-denticulate on both sides, the largest 3 mm. long, 

 r/j — 1^4 mm. broad; of the branches less unequal-sided, subfalcate, acute, 

 the largest of the ultimate branchlets I'A mm. long, ^-2 mm. broad; leaves 

 of the upper plane of the main rachis cordate at the base, subauricled 

 on the outer side, subcuspidate-acuminate, pellucid-margined, piloso-den- 

 ticulate, the largest 2'.4 mm. long, 1 mm. broad; of the branches more 

 distinctly cuspidate, the largest of the ultimate branchlets hardly 1 Vs mm. 

 long, under 'A mm. broad. Spikes hardly more than 5 mm. long, 2 mm. 

 broad; sporophylla of the upper plane oblique-oblong, very unequal-sided, 

 keeled, more or less distinctly pellucid-margined and slightly piloso-den- 

 ticulate ; of the lower plane equal-sided, ovate, acuminate, setiform at the 

 point, pale-green, keeled, the base auricled, the margin slightly piloso- 

 denticulate; macrospores yellowish, minutely granulate on the basal side; 

 microspores densely and coarsely verrucose.

Shoots tufted, suberect, TVs — I?'/? cm. long, copiously pinnate, the 

 stem naked, thick-spongy below, stramineous or brownish, 2-sulcate down 

 the face; pinnae copiously compound. Leaves heteromorphous; lateral 

 leaves spaced and spreading on the main stem, approximate and erecto- 

 patent on the branchlets, ovate-rhomboid or oblong-rhomboid, 2 — 37* mm. 

 long (after Spring 4 mm. long, 2V2 mm. broad; probably those of the 

 main rachis), subacute or blunt, pale-green, membranaceous, the upper 

 side minutely serrulate, broadly rounded or cordate at the base, the 

 lower side subentire (after Hieronymus minutely serrulate), narrowed 

 at the base; intermedial leaves Vs as long, ovate, long-cuspidate, minutely
