rounded at the base, the largest leaves 5 mm. long and IV2 mm. broad, 

 with the midrib thickened towards the apex; of the branchlets similar 

 but smaller, spreading, less unequal-sided, not rarely cuneate on the lower 

 side at the base ; leaves of the upper plane erect ; of the stem remote, 

 oblong, cuspidate-acuminate, minutely serrulate on both sides but less 

 copiously on the outer side, obliquely cordate at the base, the outer base 

 much produced, hamate-incurvate, the largest leaves 3 mm. long, the 

 cusp 'A — 'A as long as the blade; of the branchlets smaller, imbricated, 

 the cusp relatively longer, the inner base rounded or cuneate, the outer 

 base rather narrowly cordate. Spikes solitary, square, IV2 mm. diam. ; 

 sporophylla ovate, 1 mm. long, hardly acuminate, minutely denticulate, 

 keeled; macrospores whitish or yellowish, often 2 in a macrosporangium, 

 more or less compressed and lentiform, finely rugulose with flexuose, 

 branched or connected rumples, the apex more or less flattened, without 

 radiating ribs, encircled by a wing-shaped crest; microspores probably 

 wanting.

Shoots creeping, or ascending from a creeping base, 30 — 40 cm. long, 

 often forked near the base, the stem yellowish when dry, I'A — 2 mm. 

 thick ; pinnae pinnate, to 7 cm. or more long ; pinnulae once or twice 

 pinnate ; ultimate branchlets to 12 'A mm. long, 3 — 4 mm. broad including 

 the lateral leaves. Leaves of the lower plane horizontal or spreading on 

 the stem, more ascending on the branchlets; of the stem jemote, 

 subfalcate-oblong, 3 — 4 mm. long, nearly 'A as broad, blunt, minutely 

 denticulate on the upper side, broadly rounded on the upper side at the 

 base, less so on the lower side ; of the branches similar to those of the 

 stem, hardly smaller, dark-green above, paler beneath, spuriously 2-nerved ; 

 of the branchlets similar, hardly contiguous, rounded and slightly dilated 

 or rotundate-cuneate on the upper side at the base, the largest 2 mm. 

 long, bluntish ; leaves of the upper plane adpressed, erected ; of the stem 

 broadly ovate, I'A mm. long, acute ("), keeled, denticulate, produced and 

 incurvate-cordate on the outer side at the base; of the branchlets similar 



(') I believe rather long-cuspidate.
