Plants small, slender, pinnate, the lateral branches leafy, often becoming 

 flagelliform in the outer part, of the Frullania type with the dorsal half-leaf 

 bifid or quadrifid, the ventral branches axillary, intercalary, leafy or flagelliform, 

 or short sexual; stem in transverse section with a unistratose cortical layer of 

 about 25 cells similar to those of the medulla. Line of leaf insertion curved, the 

 dorsal half transverse, the ventral half oblique, the leaves succubous. Leaves 

 subquadrate in outline, divided to one-half or two-thirds of their length into five 

 or seven slender segments, for the most part consisting of a long hyaline tip cell 

 at a right angle to the leaf and parallel to the stem or branch. Underleaves 

 quadrifid (trifid), similar to the leaves. Plants dioicous; female inflorescence on 

 a short ventral sexual branch, the bracts and bracteoles similar, in two or three 

 series, different from the leaves, the bracts of the inner series deeply quadrifid. 

 Male inflorescence, perianth, and sporophyte not seen. 



Type species: Psiloclada clandestina Mitten. 



The genus is known from South Africa, the Malayan Archipelago, Tasmania, 

 and New Zealand. It does not occur in South America. The species which has 

 been reported from South America is a Microlepidozia.

Leafy stems turgid, ascending to erect, in tufts or scattered among other 

 bryophytes (the American species) , more or less radially symmetric from a 

 closely branched rhizome system of flagelliform and stolon-like prostrate axes; 

 branches ventral intercalary, as leafy stems, flagelliform branches, stolons or 

 rhizomes. Leaves [American species] subquadrate to rectangular, bisbifid, or 

 quadrifid, trifid, rarely bifid above, often of two layers of cells below. Underleaves 

 similar, as large as the leaves or nearly so. Plants dioicous, the male and female 

 inflorescences on short, erect, leafy branches from the rhizome or its branches. 

 Male inflorescence terminal becoming intercalary, trigonous, the bracts and 

 bracteoles similar, like small concave quadrifid leaves; antheridia in the axils of 

 the bracts. Female inflorescence with three or four series of bracts and bracteoles 

 like the leaves but increasing in size to the innermost series. Perianth cylindrical 

 below, 3-keeled above, the keels rounded, inflated, the mouth contracted. Sporo- 

 phyte not seen. 



Type species: Jungermannia nutans Hooker & Taylor, London Jour. Bot. 3:
