Plate XXXVIII 



Loosely widely cespitose, glaucous-green, brownish when old; primary 

 stems creeping, flagellate, robust, with numerous, more or less erect, secondary 

 stems and branches usually up to height of 2-4 cm; leaves somewhat com- 

 planate, broadly Ungulate-obtuse from a broadly ovate base, thick, opaquely 

 chlorophyllose, entire, very densely papillose on both sides; costa pellucid, 

 rather strong, vanishing below apex; leaf-cells minute, about .009-. 012 mm, 

 rounded-hexagonal, the median basal elongate and non-papillose, the alar 

 scarcely different from the upper; perichaetial leaves sheathing: seta erect, 

 about 1 cm high, sinistrorse; capsule erect, castaneous, symmetric, oblong- 

 cylindric, about 3:1, the mouth small; lid conic-acuminate, about two-fifths 

 as long as urn; annulus present, large; peristome-teeth narrowly lance-linear, 

 hyaline, faintly papillose, about 8-10-nodose-articulate, the divisural and dorsal 

 lamellae x'ery faint or not visible; segments very short or rudimentary, or none, 

 from a very low basal membrane; exothecial cells rather thin-walled, irregularly 

 quadrate to oblong-rectangular; spores maturing in late fall or in winter, 

 medium to thin-walled, brownish, papillose, .009-.012 mm in diameter. 



On rocks and trees, in woods, usually at the base of trees; Asia and from

3. Anomodon viticulosus [Linnaeus] Hooker and Taylor 



Large, widely tufted, dark green above, yellowish within: stems creeping, 

 long, sending up secondary stems and branches, the secondary stems 4-10 cm 

 long, sometimes becoming more or less geniculate by repeated innovations: 

 leaves more or less crisped when dry, sub-falcate, secund, lance-lingulate from 

 an ovate base, frequently serrulate at the apex, apex bluntly acute; costa 

 strong, pellucid, ending a little below the apex; median, upper, and lower 

 marginal leaf-cells opaque, minute, rounded-quadrate, the median basal some- 

 what elongated, cells minutely papillose; perichaetial leaves long, linear-acu- 

 minate from an ovate base: seta twisted when dry, erect; capsule oblong- 

 cylindric, symmetric or slightly curved, about 3:1; lid narrowly conic; peris- 

 tome-teeth lance-linear, more or less irregular, yellowish, the inner peristome 

 consisting of a very low basal membrane and irregular segments up to 1/2
