pi. 345, f. 7, 8. 1877. 



Plants very small, brownish, reddish-brown or black, in tufts or scattered 

 anions other bryophytes; stems filiform, erect, radially symmetric, 1-2 cm long, 

 sparingly branched, the branches lateral, the half-leaf with two major segments, 

 at the dorsal base of the branch. Rhizoids in fascicles from the lamina of the 

 underleaves, the tips much branched. Line of leaf insertion transverse. Leaves 

 small, distant, subquadrate, 0.48 mm long, 0.45 mm wide, quadrifid (rarely 

 trifid) to three-fourths of their length, with a conspicuous, spreading, decurved 

 tooth from the basal margin of the lamina on both sides; segments two to four 

 cells broad at the base, to twelve cells long, the margins with short, spine-like 

 cilia oue to three cells long, singly or in one to three opposite pairs ; lamina 

 with a few marginal cilia and the pair of longer basal teeth, and with 1-3- 

 toothed superficial spines scattered on the ventral surface below the segments; 

 leaf-cells 27-36 p. X 20-27 p., the walls thin, the trigones inconspicuous, the 

 cuticle striolate. Underleaves like the leaves. Plants dioicous. Male inflorescence 

 terminal on the stem or branch, soon becoming intercalary in position, the bracts 

 and bracteoles in four to six series, the bracts concave, slightly larger than the 

 leaves, with a larger lamina and shorter segments with more spines and cilia 

 than the leaves, without the conspicuous basal pair ; antheridia one or two in the 

 axils of the bracts. Female inflorescence terminal on the stem, with one or two 

 subfloral innovations, the bracts and bracteoles larger than the leaves and under- 

 leaves, of similar pattern but with six to eight pairs of cilia on the segments 

 and more cilia on the margins of the lamina, the basal pair of teeth also ciliate. 

 Perianth long, cylindric with three rounded keels above, the mouth broad, trun- 

 cate, short-spinose. Fig. 3, a-g.

There are many reports of the species in the literature, including: from this same area, 

 those of Angstrom (1872), Arnell (1955), Bescherelle & Massalongo (1889), Evans (1898), 

 Gola (1923), Herzog (1954, 1957), Kiihnemann (1949), Massalongo (1885, 1908, 1927b), and 

 Stephani (1900 a, b, 1911). 



The species has also been found on Tristan da Cunha (Arnell, 1958) and Kerguelen 

 Islands (Mitten, 1877, 1884).
