 Without an inferior lesser lobe. 



Perianth leafy, fruit lateral. 

 Leaves and Stipules] entire, or with apices truncate, dentate ; perianth 

 in the lower part of the stem ; 3-gonous. 



Stems creeping and rooting or ascending, large, sparingly 

 branched, giving off numerous filiform leafless shoots. 

 Leaves distichous, incubous, usually 3-fid at the apex. 

 Stipules toothed, often connate with the leaves above them. 

 Fruit (and antheridia) terminal, on short proper branches, 

 arising from the bracts of the stipules. Involucral leaves 

 small, narrow, incised at the apes. Perianth elongate, 

 3-angular ; mouth 3-toothed. Calyptra membranous. 

 Capsule globose, on a slender fruit- stalk ; elaters with 2 

 spiral fibres. Antheridia 2, in the axil of each perigonial 

 leaf. 



A tropical and sub-tropical genus, rare in Europe and 

 North America, most abundant in Australasia. The 

 species are often broad and flat, some resembling 

 Lojphocolea in general habit, but the stipules are con- 

 nate with the leaves, above (not below) them.
