of the branches and upper part of the main rachis heteromorphous; 

 lateral leaves somewhat distant on the main rachis, approximate or 

 contiguous on the branchlets, subspreading or somewhat ascending, recurved 

 and rugulose when dry; those of the branchlets rhomboid-oblong, the 

 largest 2 — 2V2 mm. long, 1 — I'A mm. broad, blunt, entire, recurved at 

 the edge, the upper base abruptly rotundate-cuneate, the lower decurrent ; 

 leaves of the upper plane erect, adpressed, lanceolate-oblong; those of 

 the ultimate branchlets close or approximate, the largest IV2 mm. long, 

 acuminate, entire, subparallel, straight or subfalcate, the higher obliquely 

 adnate, cuneate and decurrent on the outer side at the base, the lower 

 peltate and rounded at the base. Spikes short, square, IV4 — 2 mm. diam.; 

 sporophylla broadly ovate, to 2 mm. long, acuminate, keeled, entire; 

 macrospores pale-yellow, purplish or brownish, rugulose or verruculose; 

 microspores yellowish or pale-orange, provided with conical or cylindrical 

 projections which may be thickened at the apex. 



Forma typica: Shoots rather large, 25 — 50 cm. long. 



Forma Hieronymi: Shoots small, 7 'A— 20 cm. long, the branched 

 portion 5 — 15 cm. long, 4— 12Vs cm. broad.

Shoots creeping, or ascending from a trailing base, 15 — 40 cm. long, 

 the stem yellowish, pubescent below with pale, deciduous hairs, as are 

 the rachises; pinnae ascending, to 25 on a side, 1 — 2-pinnate or once to 

 twice forked, rarely simple; ultimate branchlets 2 — 3 mm. broad including 

 the lateral leaves. Leaves heteromorphous; lateral leaves spreading; of 

 the stem remote, ovate, hardly oblique, IV2 — 2V2 mm. long, acute, subentire 

 towards the apex, the upper side denticulate, ciliolate towards the sub- 

 cordate or rounded base, the lower side entire, or sparingly ciKolate at 

 the rounded or truncate-cuneate base; of the branchlets similar to those 

 of the stem but smaller, close or more or less imbricate; intermedial 

 leaves erect; of the stem broadly ovate, very oblique, V* — IV2 mm. long, 

 cuspidate-acuminate, minutely denticulate, the inner base rotundate-cuneate, 

 the outer base produced, rounded; of the branchlets cuspidate, hardly 

 denticulate, keeled. Spikes square, 6 — 12 mm. long, VU — 2 mm. diam.; 

 sporophylla ovate, 'A — 1 mm. long, acute, ciliolate-denticulate; macrospores 

 pale-grey or yellowish-white, irregularly rugulose-verruculose ; microspores
