COLOMBIA: s.L, Wallis, type of S. wallisiana (G) ; Paramo El Bogueron, 3500 m,

 (Hb. Herzog); Tungurahua, near Las Torres, 3500 m, Asplund (Hb. Herzog). 



The species is readily recognized because of the long-acuminate tips of the 

 leaves and underleaves. They are fragile and easily broken, but can usually be 

 seen at the apex of the stem. The tip cells are much longer than broad. 



8. Herberta angustivittata (Stephani) Fulford, comb. nov. 



Schisma angustivittata Stephani, Spec. Hep. 4: 12. 1909. 

 Schisma simplex Stephani, Spec. Hep. 6: 362. 1922. 



Plants of small to medium size, dark greenish-brown to brown, in tufts; 

 leafy stems to 5 cm long, to 1 mm wide, often beginning as small-leaved branches 

 from a eaudex or rhizone with scale-like leaves, rarely branched. Rhizoids 

 abundant, from the scale leaves of the flagelliform branches and the rhizome. 

 Leaves imbricate, erect-spreading, 2-3 mm long, to 1.5 mm wide, short, rectangu- 

 lar, bifid to one-half ; the segments triangular from a wide base, tapering to the 

 acute or short-acuminate apex, the margins entire or with occasional coarse 

 teeth, the vitta less than one-fourth the width of the base of the segment base, 

 ending below the apex ; lamina subrectangular, the margins scarcely convex, 

 with coarse teeth near the base, the vitta strong, bifurcate a little above the 

 base, the basal cells of the segments and of the dorsal base with thick irregular 

 walls, the pits and trigones scarcely evident. Plants dioicous. Female inflorescence 

 terminal, with one subfloral innovation, this often becoming floraliferous, the 

 bracts and bracteoles in three to six series, similar, and similar to the leaves and 

 underleaves, the inner series larger, the margins coarsely toothed. Perianth 

 (immature) 3-parted for half the length, the divisions bilobed, the segments 

 coarsely toothed. Male inflorescence and sporophyte not seen. Fig. 8, a-g. 



Habitat : On trees in forests.

 and Brazil (Herzog 1925a).
