(187) S. Klttyae, r. A. r. JR., Bull. Btz., 1912, VII, 35; S. per- 

 mutata, Hieron., forma viridifolia, v. A. v. R., 1. c., 1911, I, 27; var. 

 aeneifolia, v. A. v. R., 1. c., 36. 



Differs from S. permutata Hieron. by the following characters: 

 Shoots 3555 cm. long, the stem dirty-red, when dry pale-brownish-red; 

 leaves of the stem hardly dimorphous, similar to those of the upper plane 

 of the stem in S. permutata; of the lower plane 45 mm. long; of the 

 upper plane 3 mm. long; leaves of the upper plane of the branchlets 

 shortly acuminate; sporophylla relatively shorter and broader, more 

 sharply acuminate, 3 A 1 mm. long; macrospores whitish to black-brown, 

 rather densely verruculose to rugulose-verruculose. 



Forma typica: Leaves bright-green above, pale-green beneath; 

 spikes green. 



War. aeneifolia: Leaves bronce-green above, olivaceous beneath; 

 spikes bronce-green.

Shoots spreading-ascending, deltoid, springing from a branched, diva- 

 ricate-scandent or intricate-decumbent, 3-stelical, smooth, glossy main stem 

 reaching a length of 3 7 m.; stems smooth, with the lower axillary 

 leaves obovate-orbicular, bluntly rounded, narrowed and narrowly 2-auri- 

 culate-cordate at the base; pinnae deltoid, 6 8 on a side, the lowest 

 pinnately compound; lowest pinnulae pinnate, central pinnulae pinnate 

 or dichotomous. Lateral leaves remote on the stem, contiguous on the 

 branchlets, flaccid, dark-green or with a tint of blue, subascending or 

 subspreading, subfalcate, ovate or oblong, 2 3V4 mm. long, bluntish, 

 entire, more or less cordate on both sides, or rounded on the upper side 

 and truncate-cuneate on the lower side, at the base, generally distinctly 

 plicate or auricled on the upper base, not imbricate over the rachis; 

 leaves of the upper plane Vs as long, oblique-oblong, entire, acute or 

 bluntly acuminate, not cuspidate, those of the principal rachises obliquely 

 cordate, of the ultimate branchlets obliquely adnate, cuneate on the inner 

 side, decurrent on the outer side, at the base. Spikes square, r i 2 ! 2 cm. 

 long, 2 mm. diam. ; sporophylla broadly cordate or ovate, shortly acuminate, 

 scarcely longer than the sporangia, those of the macrosporangia much the
