rounded at the base, rather dilated on the upper side at the base, 

 slightly imbricate over the stem or rachis; leaves of the upper plane erect, 

 adpressed, broadly lanceolate, to ",4 mm. long, acuminate, denticulate; 

 leaves of the branchlets similar, but smaller. Spikes copious, oblong,

 not imbricate, hardly contiguous, oblong, Vs mm. long, more or less 

 acute, slightly keeled, minutely . denticulate on the upper side; of the 

 lower plane 'A as long, erect, ovate-lanceolate, acute, denticulate; 

 macrospores white to yellow, minutely papilloso-verruculose (Hieron., 

 1. c, 699), smooth to reticulate (in Zollinger's No. 3313 and conf.

Shoots probably erect from a creeping base, caespitose, lanceolate in 

 outhne, when adult 10 — 15 cm. long, Vh — 4 cm. broad at the middle, 

 the stem stramineous, compresso-terete, slightly grooved, Va mm. thick, 

 2 mm. broad including the lateral leaves ; pinnae erecto-patent, the central 

 ones the largest, IV2 — 4 cm. long, pinnate; pinnulae simple or forked; 

 branchlets to V/4 cm. long, 1 mm. broad or hardly broader including the 

 lateral leaves. Leaves heteromorphous; leaves of the lower plane very 

 distant on the stem, less so or even contiguous on the branchlets, nearly 

 erecto-patent; of the stem broadly ovate-oblong, very unequal-sided, nearly 

 1 mm. long, nearly 'A mm. broad near the base, acute or subacute, with 

 the upper edge minutely denticulate, the lower edge obsoletely so, the upper 

 base dilated, rounded or rotundate-cuneate, imbricated over the stem, the 

 lower base rather narrowly rounded; of the branchlets similar but 

 somewhat smaller; leaves of the upper plane erected, distant on the 

 stem, contiguous on the branchlets; of the stem ovate, 1 mm. long, nearly 

 straight, acuminate, minutely denticulate on the inner edge, obsoletely 

 so on the outer edge, the base obliquely rounded, somewhat produced 

 and apparently slightly peltate; of the branchlets similar but smaller, 

 hardly produced at the base. Spikes short, oblong, 2—4 mm. long, V/i—2 

 mm. broad; sporophylla of the upper plane 2 — 4 on a side, subascending, 

 lanceolate, very shortly mucronate-acuminate, keeled, minutely denticulate 

 on the upper edge; those of the lower plane suberect, ovate, acuminate, 

 keeled; denticulate on both edges; macrospores yellowish- white, finely
