the segments triangular or subulate, one or two shorter than the rest, the cells 

 as in the leaf. Plants dioicous. Male inflorescence intercalary on a branch, the 

 bracts and bracteoles in several series, the bracts smaller than the leaves, concave, 

 bifid, with a tooth on each side of the lamina, the bracteoles small, plane. Female 

 in florescence and perianth not seen. PI. 51. Fig. 7, a-f. 

 Habitat: On soil.

Plants small, pale green to yellowish-green, in mats; leafy stems radially 

 symmetric to dorsiventral, erect or prostrate, regularly or irregularly pinnate 

 to bi-tripinnate; lateral branches long, leafy, of the Frullania type with the 

 quadrifid, bifid or subulate half-leaf dorsal, sometimes becoming attenuate- 

 flagelliform in the outer part; ventral branches axillary, intercalary, leafy, or 

 flagelliform with scale-like leaves, or short, sexual; stems in transverse section of 

 a unistratose cortical layer of six, nine, twelve, fifteen or eighteen, large, thin- 

 walled cells surrounding the medulla of smaller cells, the number of cortical 

 cells equaling the number of segments of two leaves and an underleaves of one 

 spiral on the stem. Rhizoids from small basal cells of the underleaves, the base 

 of a ventral branch, or the scales of the flagelliform branches. Line of leaf 

 insertion transverse, the basal cells "wedged in" between adjacent horizontal 

 rows of cortical cells. Leaves divided to one-half or more into four, five or six 

 segments; or to the base, or to within one-half cell of the base, into two, three 

 (or four) segments; segments uniseriate throughout, four to six or eight cells 

 long, the lamina one-half, one, two, three or four rows of cells high, or absent, 

 the margins without teeth; cells thin- walled, longer than broad. Branch leaves 

 and underleaves with one or two segments less. Underleaves as large as and 

 similar to the leaves, or much reduced, bifid-trifid and two to four cells long. 

 Plants dioicous or autoicous (K. Miiller, 1956). Male inflorescence terminal 

 on a leafy stem or long branch, becoming intercalary in position, the bracts and 

 bracteoles in five or more series; antheridia in the axils of the bracts. Female 

 inflorescence without innovations, terminal on the stem or long branch, or a 

 short ventral axillary sexual branch, in one species the ventral sexual branch 

 sometimes at the base of a lateral branch; bracts and bracteoles similar, in 

 three to four series, different from the leaves. Perianth long, terete below, three- 

 lobed above, of one layer of cells, the mouth contracted. Shoot/sporophyte 

 relationship a shoot-calyptra. Capsule ovoid-cylindrical, reddish-brown, the wall 

 of three layers of cells with characteristic markings; seta of eight or sixteen rows 

 of large cells surrounding many smaller cells. Sporeling of the Nardia type, a 

 small mass of cells developed outside the old exospore, from which the leafy plant 

 develops. 



Type species: Blepharostoma sejuncta Angstrom (Lepidozia chaetophylla 

 Spruce, as a synonym) .
