■3. Cephalozia elacMsta, Jack. Paroecious. Stems very small and some- 

 what rigid. Leaves variable, inclined to quadi'ate, deeply bifid 

 but sometimes entire, segments nearly linear, bearing occa- 

 sionally a well-developed tooth or two, but more frequently with- 

 out teeth. Amphigastria generally present, especially among 

 the perichgetial leaves. Involucral bracts much larger than the 

 cauline leaves, irregularly lobed, lacerated at the margin, and im- 

 bricated on every side. Perigonial leaves strongly toothed at 

 their margins, and terminating in longish incurved points. 

 Gamoecium and Androecium on same branch, but separate (paroe- 

 cious). Colesule roundish or inclined to triangular, but rather 

 variable in form, contracted and ciliated at the mouth. Anthe- 

 ridia with short stalks in the axils of the perigonial leaves, 

 singly.

I have enumerated this so-named plant out of deference to some of our 

 greatest hepaticists, although I am by no means clear about the 

 characters which distinguish it from C. divaricata. Dumortier 

 places the two in different sections of Cephalozia, and refers C. 

 divaricata to the figure in English Botany quoted, and C. byssacea 

 to the figure in Hooker's British Jungcrmannioe. I had collected in.
