[VOL. 11 



coarse, to 15 em long, with leaves to 3 mm wide, rarely branched, the branches 

 leafy. Line of leaf insertion transverse. Leaves irregularly spreading, the bases, 

 imbricate, 3.5-4 mm long, 1-1.3 mm wide, unequally bifid to one-half of their 

 length; segments lanceolate, tapering to a tip of one or two cells, the margins 

 obscurely to coarsely serrate or dentate, the vitta at least half as wide as the 

 base of the segment, ending some distance below the apex ; lamina more or less 

 ovate, the margins with appendages in the lower half, the vitta bifurcate just 

 below the sinus. Plants dioieous. Female inflorescence terminal on the stem, 

 with one or two subfloral innovations, the bracts and bracteoles of the inner- 

 most series coarsely serrate. Perianths deeply 3-parted, the divisions deeply 

 bilobed, the segments serrate as in the female bracts. Male inflorescence and 

 sporophyte not seen. Fig. 6, a-e.

Plants of medium size, bright rose-red to purplish or light brown, in tufts; 

 stems robust 10-15 im long, with leaves 3-4 mm wide, simple, rarely branched. 

 Line of the leaf insertion transverse. Leaves irregularly spreading, the ba^i s 

 imbricate, 3-4 mm long, 1-1.5 mm wide below, bifid to one-half of their length 

 or less ; segments triangular from a broad base, tapering to a long-acuminate 

 apex of elongate cells, curved, the margins entire, the vitta about half the 

 width of the base of the segment; lamina broadly ovate, the margins toothed 

 and appendiculate below, the vitta broad, bifurcate some distance below the 

 sinus; leaf-cells very thick-walled with thin-walled pits, the cuticle rough. 

 Underleaves similar to the leaves, the segments less curved. Male and female 

 inflorescences and sporophytes not seen. Fig. 7. a-d.
