Section 4. Appendiculatae 



The plants of this section are for the most part large to robust. The leaven 

 are attached in an oblique line which is hook-form above, and arc sharply 

 3-toothed, obscurely 3-toothed, subentire or undivided. The ventral base of the 

 leaf is always dilated to a greater or lesser degree, forming an entire, serrulate, 

 dentate, incised, or appendiculate auricle. The underleaves are large and cordate 

 to incised-appendiculate at the base from a recurved line of insertion.

Plants very large, light yellow-green, becoming light brown; stems stout. 10 

 cm or more long, with leaves to 6 mm broad, erect; lateral branches infrequent, 

 1 cm or more apart, diverging at a wide angle; flagelliform branches infrequent, 

 long, the scale-leaves large, broader than the branch, to 0.35 mm long, ovate. 

 Leaves always spreading, subimbricate to imbricate, asymmetrically long-ovate, 

 a little falcate, to 4 mm long, 2 mm broad at the base, narrowing to the rather 

 broad, transversely truncate, tridentate apex, the dorsal margin strongly curved 

 from a deeply cordate base, the ventral base conspicuously auricled, the auricle 

 oblong, undulate and lobed, crenulate, serrate ; teeth broadly triangular, acute, 

 five to ten cells long and five to ten cells broad at the base, the margins straight 

 to repand; leaf -cells thin-walled, the lumina angular-rounded, the trigones small, 

 conspicuous, often becoming confluent, the cuticle strongly verruculose ; cells of 

 the apical region averaging 22 X 22 ^. Underleaves imbricate, twice as broad 

 as the stem, subquadrate in outline, somewhat squarrose, 0.8-1.4 mm long and 

 wide, the base strongly cordate, the auricles large, undulate, their margins lobed, 

 serrate and often short-ciliate, the apex and lateral margins lobed and toothed, 

 the lobes broad and shallow, crenulate to serrate, often dentate or short-ciliate. 

 Female branches occasional, the bracts of the intermediate and innermost series 

 broadly ovate, divided to one-third or one-fourth of their length into usually 

 three long, dentate to ciliate segments, the cells 72-90 X 20 p., with thin walls. 

 Perianth long, the mouth long-laciniate, the laciniae crenulate to ciliate, mostly 

 twelve or more cells long. Male branches and sporophytes not seen. Fig. 41. a-g. 



Habitat: In deep tufts on stumps, logs and tree trunks.
