Dioicous, ci^spitose, small to medium in size, pale or dark 

 green to greenish-brown in colour. Stems erect or procumbent, 

 arcuate serpentine, rigid, simple or furcate ; radiciilose, rootlets 

 whitish, few. Leaves sub- vertically inserted, horizontal, imbricate, 

 subrotund, tridentate (very rarely bi-quadridentate) to about ^, 

 sinuses acute or rounded, segments acute, margin of leaf entire 

 with the exception of a small postical basal tooth ; texture some- 

 what firm, cells smallish, roundish-quadrate, walls firm, trigones 

 small, distinct. Stipules simple, bifid or bipartite, with one or 

 two longish cilia or teeth near the base, segments linear-lanceolate, 

 entire. Bracts quadrifid, undulate. Bracteole broadly ovate, 

 bidentate. Perianth terminal, oblong, acutely plicate above. 



Male plant not seen. 



Dimensions. — Stems J to 1 J inch long, diam. "3 mm. to '4 mm., 

 with leaves 2' mm. broad; leaves 1'2 mm. long x I'S mm. broad, 

 segments '3 mm., 1* mm. x 1* mm., seg. -3 mm., '9 mm. x l"! mm., 

 seg. "3 mm.; cells -03 mm., '02 mm., '03 mm. x '025 mm.; 

 stipules '7 mm. long x '3 mm, broad at the base, '7 mm. x "25 mm., 

 •35 mm. X *2 mm. 



Obs. — There is little doubt that this is merely a variety of 

 Jung er ma Ilia lycopodioidei<. Wallr., from which it is distinguished 

 by its smaller size, segments not mucronate, and, instead of being 

 furnished with large basal cilia, a short simple segment only is 

 evident. The stipules are not so ciliate. 



I have seen neither ^ or $, the description of bracts, bracteole 

 and perianth being taken from Nees "Eur. Leber." 



A number of forms are described by Nees, the most striking 

 being var. Nauinauniana, N., which is found with us ; except in 

 the largeness of its size, I see nothing to separate it from var.
