of the calyptni. Perianth ahiiost always elongate, ovate-subulate 

 or narrowly fusiform, upper portion obtusely trigonous, in E/i- 

 Lepidozia carnose, mouth entire or denticuhite, Micro- Lepidozia 

 leptodermous, mouth ciliato-laciniate. Calyptra 2-4 times shorter, 

 pyriform or oblong, below somewhat carnose, or in Micro- Lepidozia 

 whole length delicate, afterwards rupturing into two hps. Capsule 

 on a more or less firm shortly exserted pedicel, oblong-cylindrical, 

 dividing to the base into 4 valves, 2-4-strata. Elaters slender, 

 bispiral. Spores minute, smooth or asperulous. Androecia very 

 often constantly on slender postical branches, rarely (and in 

 Micro-Lepidozia principally) terminal on lateral branches ; peri- 

 gonial bracts 5-10 pairs, suborbiculate concave, apex bidentate ; 

 antheridia solitary large pedicellate.

Dioicous, densely csespitose, flagelliferous, medium size, 

 greenish to olive or reddish-brown in colour. Stems creeping or 

 suberect, curled, on a cross-section 16 x 20 cells in diameter, 

 cortical about 50, these and the next inner layer large with thick, 

 dark walls, inner cells smaller with thinner walls, of a light golden 

 brown colour; closely pinnate or bipinnate, branches alternate, 

 unequal, often attenuate, apices fiagelliferous. Leaves incubous, 

 closely imbricate, patent or ])atent-divergent, incurved, very con- 

 cave, cordate-orbiculate or broadly subquadrate-cordate, quadrifid 

 to nearly the ^, segments acute, 8 to 12 cells broad at the base, 

 sometimes even more, postical segments much inflexed ; cells 

 smallish, opaque, subquadrate-hexagonal. \valls thick, angles
