[VOL. 11 



obscurely bi- or tridentate apex ; teeth acute, two to four cells high, three to 

 eight cells broad at the base, the margins entire ; leaf-cells more or less quadrate 

 in outline, thin-walled, the trigones small, conspicuous, seldom becoming coa- 

 lesced, the cuticle verruculose; cells of the apical region mostly 17 X 17 p.. Under- 

 leaves distant to approximate, attached in a straight line, subquadrate in outline, 

 a little broader than the stem, 0.28-0.36 mm long and broad, the apex straight, 

 undulate, 2- to 4-lobed or occasionally with one or two short, sharp teeth. Male 

 and female branches not seen. Fig. 20, a-b. 



Habitat : In depressed mats or scattered among ferns. 

 TRINIDAD: Without locality or collector (NY). 



BRAZIL: Tauau near Par/i, Spruce, Hepat. Sprue, (isotypes G, NY). 

 VENEZUELA: s.l., Fendler, type of M. venezuelanum (G). 



In general appearance the species is similar to B. affinis. It differs, however, 

 in that the underleaves are not hyaline except for occasional marginal cells, and 

 trigones are conspicuous.

Plants small, golden-brown, becoming darker; stems slender, 3 cm or more 

 in length, with leaves to 2 mm broad ; lateral branches mostly more than 1 cm 

 apart, diverging at a wide angle ; flagelliform branches occasional. Line of leaf 

 insertion little curved in its upper part. Leaves distant, spreading, ascendent, 

 strongly deflexed when dry, asymmetrically ovate, mostly 1 mm long, 0.5 mm 

 broad at the base, narrowed a little to the broad, transversely truncate, triden- 

 tate apex ; teeth acute, three to six cells long, three to five cells broad at the base, 

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

 gones conspicuous, sometimes becoming coalesced, the cuticle faintly verruculose ; 

 the cells of the apical region mostly 24 X 24 p.. Underleaves distant, round- 

 quadrate, entire, scarcely broader than the stem, 0.28 mm long and broad, the 

 margins rounded, the cells 20-24 p. long, 16 p. broad, the walls uniformly thick- 

 ened, especially along the margin. Sexual branches not seen. Fig. 21, a-d. 



Habitat: On bark of rotten logs, dark gorge of Mist Forest (Schultes).
