ametric or oblong-hexagonal, thin-walled or with walls scarcely 
thickened, trigones small or lacking: underleaves always present, 
usually large, broadly ovate, suborbicular or broadly reniform, apex 
entire, retuse or bilobed, lobes often equally or unequally bifid : 
dioicous, autoicous or paroicous; sexual branches axillary to the 
underleaves: 2? bracts in 2 or 3 rows, very much smaller than the 
leaves, subrotund, ovate or lanceolate, entire or 2 to 4 lobed, sub- 
connate ; bracteoles similar ; perianth lacking ; archegonia less than 
12: perigynium developed from the @ branch, pendulous, subter- 
ranean, carnose, many cells thick, radicelliferous, clavate or subcylin- 
drical, the apex crowned by the persisting bracts and bracteoles, the 
interior surface papillate ; calyptra nearly as long as the perigynium, 
adnate almost to the apex, the free portion bearing the sterile arche- 
gonia: capsule cylindrical, the four linear, spirally wound valves 
2 cells thick, the inner layer with numerous semiannular bands, which 
are nearly lacking in the outer layer ; “involucellum” highly devel- 
oped, finally adnate to the calyptra and reaching to the line of separ- 
ation of calyptra and perigynium walls, its cells elongated and sinu- 
ous: elaters long, slender, blunt, bispiral ; spores minute, about the 
diameter of the elaters. 
Apex of leaves subtruncate or rounded, verruculose ; underleaves retuse.

Apex of leaves usually cuspidate ; underleaves deeply bifid, lobes triangular. 
K. cuspidata. 
Apex of leaves usually bidentate. 
Leaves large, 1.25™™x1.1™™, teeth 1 to 3 cells long; underleaves bifid 
about two-thirds. K. Tosana. 
Leaves small, about 0.65""x0,5™™, teeth 3 or 4 cells long ; underleaves bifid 
to within a cell of the base. XK, bifurea.
