uniseriate tip of two to four cells, 18-24 p long; leaf-cells at the base of the 

 segments 18-24 x 18-22 p, the walls thickened, the trigones distinct, the cuticle 

 smooth. Stem underleaves distant, as wide as the stem, concave, quadrifid to 

 one-third or more, the segments narrowly triangular from a 3- to 6-celled base 

 and ending in a 2- to 4-celled tip, the cells 18-24 p long, the lamina with one or 

 two obscure to well developed teeth on each side. Branch leaves and underleaves 

 larger, less concave, the segments with tips to 10 cells long. Sexual branches and 

 sporophytes not seen. PI. 43. Fig. 21,a-c. 



Habitat: On trunks of trees in mountain forests.

Lepidozia auriculata Mitten ms. 



Plants large, robust, greenish to yellowish-brown, stems to 7 cm or more long, 

 with leaves to 1 mm broad, regularly pinnate, rarely bipinnate, dendroid; lateral 

 branches mostly 5 mm apart, short, less than 5 mm long, with decurved tips, 

 occasionally with a short branch, or sometimes longer and becoming long flagelli- 

 form, the ventral branches not seen. Line of leaf insertion subtransverse, with a 

 decurved dorsal end. Stem leaves large, distant to imbricate, concave-cucullate, 

 saccate, very broadly orbicular-ovate, to 1 mm long, 1.3-1.5 mm wide at the base, 

 the lamina broadly orbicular, the dorsal margin strongly convex and covering 

 the stem, semicordate to auriculate-appendiculate, the margin with occasional 

 multicellular spines or cilia, with cells 24-27 p. long, the ventral margin shorter, 

 with an occasional tooth, quadrifid to one-sixth or one-eighth of their length; the 

 segments unequal, connivent, short, triangular from a 4- to 8-celled base, ending 

 in a uniseriate tip of two to four cells 18 p. long; leaf-cells at the base of the 

 segments mostly 18-22 X 18 p. the walls thickened, the cuticle smooth. Stem 

 underleaves as broad as the stem, averaging 0.56 mm long, 0.65 mm wide, ovate- 

 truncate, quadrifid to one-fourth of their length, the segments narrowly triangular 

 from a 4-celled base and ending in a uniseriate tip of four to six cell 18 p long, 

 the lateral margins with one or two long teeth, a long appendage at the base; 

 branch leaves and underleaves tending to be longer and not so wide, with longer 

 segments and marginal cilia, the cells mostly 18 p long, never more than 27 p. 

 Sexual branches and sporophyte not seen. PI. 43. Fig. 22, a-c. 



Habitat : Not given.

 Chimborazo, Jameson (PC); w base of the Andes, Jameson 48, Hb Mitten (BR. XY). 



In general appearance the species is quite similar to L. andicola but the two can 

 readily be separated in that the cells of the cilia and segments of both the leaves 

 and underleaves of L. andicola are very long, to 36 p or more, while those of 

 L. auriculata are short, only 18 p long or very rarely a few 22-27 p.
