the outer base decurrent and varying from cuneate to rotundate-cordate. 

 Spikes square, 'A — 7 cm. long, 1—2 mm. diam.; sporophylla rather crowded, 

 erecto-patent, ovate-acuminate, keeled, pellucid-margiued, finely serrulate; 

 macrospores white to brown, more or less distinctly rugulose or reticulate ; 

 microspores whitish or yellowish, provided with reticulated, membranous 

 crests. — Very variable. The type has the axillary leaves of the stem 

 large, elongate-obovate, 2-calcarate-auriculate at the base, the leaves of the 

 stem similar to those of the branches but larger and (or) broader, and the 

 leaves of the upper plane conspicuously 2-auriculate-cordate at the base, 

 the outer auricle much produced and hamate-incurvato, the inner auricle 

 often hardly so. — S. Guichenotii Hieron. is a sarmentose form only.

Shoots probably ascending or erect from a short-creeping base and 

 perhaps reaching a length of 50 — 60 cm., pinnate or forked and pinnate 

 in the upper part, the stem 3-stelical, compressed and fulvous when dry; 

 pinnae pinnate, lanceolate or linear-lanceolate in outline, 10 — 20 cm. long 

 and 3 — 6 cm. broad; lower and central pinnae pinnate again, higher 

 simple or forked, the largest to 5 cm. long; ultimate branchlets 3 — 5 mm. 

 broad including the lateral leaves. Lateral leaves ascending; of the main 

 and secondary rachises more or less conspicuously remote, unequal-sided, 

 oblong, bluntish, acute or shortly acuminate, entire, pellucid-margined, 

 unequally rotundate-cuneate at the base or the lower base rounded, 

 the largest leaves 5 mm. long; of the branchlets similar but less 

 unequal-sided, crowded, 2V2 — S'A mm. long, to TA mm. broad; inter- 

 medial leaves more or less falcate-oblong, mucronate-acuminate, entire, 

 pellucid-margined, rotundate-cuneate at the base; of the main rachis 

 3V2 mm. long; of the branchlets to 2 mm. long. Spikes square, 5 — 8 mm. 

 long, IV2 — 2V2 (after Hieronymus 3V2 — 4) mm. diam.; sporophylla sub- 

 isomorphous, ovate, mucronate-acuminate, pellucid-margined, entire, keeled, 

 the largest 2 'A mm. long; macrospores dirty-white or dirty-yellow, irregu- 

 larly verruculose to rugulose; microspores yellowish-white, provided with 

 sessile, capitate projections on the basal side.
