Plants of medium to large size, green becoming tinged with brown, in deep 

 springy mats or loose tufts; stems 10 cm or more long, with leaves to 1.5 mm wide, 

 regularly pinnately branched, the lateral branches 8-10 mm long, rarely branched, 

 becoming attenuate flagelliform toward the tips, ventral fiagelliform branches 

 infrequent. Rhizoids from the scales near the tips of flagelliform branches. Line 

 of leaf insertion somewhat oblique. Stem leaves imbricate or distant, asymmetric, 

 broadly ovate, truncate, concave, averaging 0.75 mm long, 0.8-1.2 mm wide at 

 the base, the lamina orbicular, the dorsal margin strongly convex to semicordate, 

 the margin with an occasional projection, the ventral margin sometimes with a 

 slender tooth, quadrifid to two-fifths or more of their length; segments unequal, 

 spreading or incurved, long-triangular from a broad base of seven (the ventral 

 one) to thirteen cells across and tapering to a slender, acuminate apex with a 

 3-celled tip; leaf-cells quadrate to rectangular, 18-27x18 fx, the walls thickened, 

 the lumina rounded, the cuticle smooth to verruculose. Underleaves large, wider 

 than the stem, subquadrate, 0.64-0.7 mm long and wide, quadrifid to the middle, 

 the segments long-tapering, the margins of the lamina with usually one slender 

 tooth on each side near the base. Sexual branches and sporophytes not seen.

Habitat: On the ground or among Sphagnum or on logs and trunks of trees 

 in mountain forests. 



Many of the plants from the higher elevations of Mexico and Guatemala have 

 considerably smaller, distant leaves and underleaves. Such plants were recognized 

 as L. hampeana and later L. truncatella var. y by Lindenberg and Gottsche. Later 

 Gottsche designated the Mexican plants as L. truncatella var. /? and Stephani 

 named them L. sandiensis, citing both Mexican and Peruvian specimens. The 

 Peruvian plants belong to L. peruviensis. Only an occasional leaf of such stems 

 has a tooth near the dorsal or the ventral base. The underleaves, especially those 

 of the branches, usually have one tooth on either side of the lamina.
