lose; cells of the apical portion 22-24 yu. rarely to 27 /x, in diameter. Underleaves 

 large, broader than the stem, subquadrate to longer than broad, averaging 1.2 

 nun long, 0.9 iiini broad, the base cordate, with very large, incised auricles and 

 long appendages similar to those of the ventral auricle of the leaf, the lateral 

 and apical margins undulate or lobed and with occasional short teeth or rarely 

 with longer teeth. Sexual branches and sporophytes not seen. Fig. 45, a-d.

This species is readily recognized by its rather short leaves nearly as broad 

 at the base as they are lon<;, with very narrow, 3-toothed apices, and the large, 

 incised, and appendicnlate auricles on the ventral base of the leaf and the cordate 

 base of the underleaves.

Plants of medium size, light brownish-green becoming darker; stems slender, 

 5 cm or more in length, with leaves to 4 mm broad; lateral branches diverging 

 at a wide angle; flagelliform branches frequent, the scale-leaves tiny, not as 

 broad as the branch, to 0.2 mm long, ovate. Leaves imbricate, strongly deflexed 

 when dry, asymmetrically ovate, spreading, 1.5-2.5 mm long, 1-1.5 mm broad 

 at the base, narrowed to the transversely to obliquely truncate, tridentate apex, 

 the dorsal margin strongly arched from a cordate base, the ventral auricle con- 

 spicuous, undulate, lobed, or occasionally toothed, the ventral margin arched, 

 ascendent; teeth variable, four to six cells long, four to six cells broad at the 

 base, the margins entire ; leaf-cells thin-walled, the lumina angular-rounded, the 

 trigones conspicuous, with convex sides, often becoming coalesced, the cuticle 

 faintly verruculose ; cells of the apical portion averaging 20 p.. Underleaves im- 

 bricate, subquadrate, 0.6-0.85 mm long and broad, the base cordate, the lateral 

 margins repand, sometimes with one to several large teeth, the apex variously 

 lobed or toothed. Sexual branches and sporophyte not seen. Fig. 46, a-b.
