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

 Spikes square, V 7 cm. long, 1 2 mm. diam.; sporophylla rather crowded, 

 erecto-patent, ovate-acuminate, keeled, pellucid-margined, 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-incurvate, the inner auricle 

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

 unequal-sided, crowded, 2 'A 3Vi 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
