Kantia miquelii (Montagne) Trevisan, Mem. 1st. Lomb. III. 4: 425. 1877. 



Plants of medium to large size, light to yellow-green becoming yellow-brown, in 

 mats or among other bryophytes; stems prostrate, to 3 cm long, with leaves, to 3 

 mm wide, frequently asymmetric with the leaves of one side smaller for a distance, 

 irregularly branched; branches numerous, leafy, ventral-intercalary from the axils 

 of the underleaves. Rhizoids in dense tufts from the bases of underleaves. Line of 

 leaf insertion longitudinal but curved at the upper end. Leaves distant to subimbri- 

 cate, faintly bordered (the cells quite similar to those adjacent), long oval to long 

 orbicular, 1.3-1.5 mm long, to 1.5 mm wide at the middle, the dorsal base straight, 

 the ventral base weakly decurrent, the apex broad, rounded, shortly bifid, the teeth 

 triangular from a broad base, to 4 cells high, the sinus U- or V-shaped; cells of the 

 border of the lower half of the leaf 60-80 X 20-25 ix, of the upper part 26-39 X 

 26-39 n, cells of the upper lamina 39-52 X 33-39 the walls uniformly thickened, 

 without trigones, the cuticle verruculose. Underleaves small, bisbifid, the outer 

 segments shorter, obscured by the large tuft of rhizoids. Male and female inflores- 

 cences and sporophyte not seen.

28. Calypogeia falcata Bischler, Candollea 18: 112. /. 37. 1962. 



Plants of medium size, light yellow-green to olive-green, in mats or among other 

 bryophytes; stems 1-2 cm long, with leaves to 3 mm wide, prostrate, occasionally 

 branched, the branches leafy, ventral-intercalary from the axils of the underleaves. 

 Rhizoids frequent, long, in hyaline tufts from the bases of the underleaves. Line 

 of leaf insertion longitudinal except at the upper end. Leaves distant to approximate, 

 bordered at least below, ovate, asymmetric, 1.4-1.6 mm long, X 0.9 mm wide at the 

 middle, falcate, the ventral side shorter, the base decurrent, the dorsal margin above 

 the middle strongly convex, the apex shortly bifid, the teeth sharp, 2 or 3 cells long 

 from a 1- or 2-celled base, occasional leaves oblong and nearly symmetrical; leaf 

 border below the middle of the leaf, of long cells 70-90 X 20-30 \x., the border in 

 the upper part, of smaller cells similar to those adjacent; cells of the upper part of 

 the leaf 42-65 X 40-52 n, thin-walled, without trigones, the cuticle weakly verru- 

 culose. Underleaves small, cuneate in outline, bisbifid, the lamina mostly 2 rows 

 of cells high, the sinus broad U-shaped, the teeth narrow or uniseriate, the cells long, 

 thin-walled. Male and female inflorescences and sporophyte not seen.
