1885. 



Plants very slender, thread-like, appearing denuded, in intricate red-brown 

 mats or among other bryophytes; stems pale green, becoming reddish-brown, 

 filiform, to 5 cm or more long, with minute leaves and underleaves, creeping, 

 suberect or pendulous, irregularly pinnately to bipinnately branched, often 

 appearing subdichotomous, the lateral branches long, branched, of unlimited 

 growth, ventral flagelliform branches frequent; stem in transverse section of 

 thick-walled cells, those of the unistratose cortical layer larger than those of 

 the medulla. Line of leaf insertion transverse or nearly so. Stem leaves distant, 

 scale-like, appressed, to 0.25 mm long, more or less quadrate, quadrifid to one- 

 third of their length, the segments subulate, at most two cells broad at the base, 

 two or three cells long, the lamina obliquely truncate, without marginal teeth; 

 leaf-cells below the segments averaging 14x18 the walls thickened, the cell 

 lumina rounded, the cuticle smooth. Underleaves narrower than the stem, plane, 

 quadrifid to one-half of their length, the segments mostly uniseriate. Branch- 

 leaves and underleaves often smaller. [Female bracts and bracteoles in three 

 series, the bracts concave, divided in the upper part into three or four segments, 

 the margins subdentate. Perianth fusiform, 3-keeled above, the mouth constricted, 

 subentire. Spruce, 1885.] Male inflorescence and sporophyte not seen. PI. 40. 

 Fig. 2, a-c. 



Habitat: Over soil in moist mountain forests. 



ECUADOR: Andes Quitenses: Mt. Abitagua, Spruce, Hb. Jack (G-368) ; Canelos, 

 Spruce (type MANCH-Kk 1490, isotype G-367); Azuay, s of El Pan, 2650-3290 m, Steyer- 

 mark 53373 p.p. (F). 



It has also been reported from Ecuador (Herzog, 1957a). 



The species is to be recognized by its filiform, denuded appearance, the irregu- 

 larly branched, red-brown stems and the small, appressed leaves with subulate 

 segments.
