(114) S. Rothertii. r. A. r. ., Bull. Btz., 1912, VII, 30. 

 Shoots trailing, caespitose, dichotomous, the secondary shoots 820 



cm. long, pinnate, the stem grooved, Va mm. thick, 5 mm. broad including 

 the lateral leaves; pinnae alternate, the highest the shortest, simple, the 

 lower to 5 cm. long, simple or sparingly simply pinnate ; ultimate branch- 

 lets 3V-2 mm. broad. Leaves weak, thin, pale-green, partly red, hetero- 

 morphous on both stem and branches; leaves of the lower plane remote 

 or approximate, spreading or horizontal; of the main stem broadly ovate, 

 unequal-sided, 2Va 3 mm. long, to 2 mm. broad, acutely acuminate, 

 rounded at the base but more broadly on the upper side, minutely den- 

 ticulate on both edges, the midrib hardly distinct; of the branches similar 

 but smaller, rotundate-cuneate at the base; leaves of the upper plane 

 erect or erecto-patent, V smaller; of the main stem ovate, nearly equal- 

 sided, acuminate, slightly obliquely rounded at the base, somewhat produced 

 at the outer base, minutely denticulate on both edges; of the branchlets 

 similar, smaller, rotundate-cuneate at the base. Spikes hardly distinct, 

 platystichous, not resupinate, simple or branched, 2 5 cm. long; sporo- 

 phylla of both planes similar to the leaves in shape and arrangement; 

 macrospores whitish or yellowish, densely finely verruculose; micro- 

 spores

(115) $1. oligopliylla. fr<rr&., Mons., I, 124. 



Small plants, with the stem slender, Vs mm. thick, grooved, yellowish, 

 the branches 3 cm. long, sparingly branched, the branchlets hardly 1 cm. 

 long. Leaves of the lower plane spreading of the stem very remote, 

 broadly ovate, 1 mm. long, obtuse, denticulate, cordate at the base, 

 produced on the upper side and slightly imbricate over the rachis; 

 leaves of the upper plane ascending; of the main rachis broadly ovate, 

 acute, ciliolate ; leaves of the branchlets similar to those of the stem 

 but somewhat smaller. Spikes 4 mm. long and 3 mm. broad; sporo- 

 phylla very dimorphous; of the upper plane about 6 on a side, spreading, 

 imbricate, ovate-oblong, 1 mm. or more long, minutely ciliolate, obtuse 

 or very shortly cuspidate; of the lower plane ascending, orbicular- 

 lanceolate, under 'A mm. long, cuspidate, hardly ciliate; macrospores 

 bright-yellow, nearly smooth, slightly finely foveolate; microspores ver- 

 ruculose.
