Cephaloziaceze that vve should look for a form presenting the 
greatest resemblance to Fossombronia , and, at the same time, the 
most primitive Acrogynous characters. On the whole, perhaps the 
genus Lophozia may be selected as a good starting-point for the 
evolution of the Acrogynae. In Lophozia, the branching is 
practically dichotomous, the leaf-insertion varies from transverse 
through succubous to nearly longitudinal, the leaves are more or 
less deeply and symmetrically bilobed, the underleaves are small
