Cephalozia. 7 



stem (acrocarpous). Bracts much larger than the subjacent leaves 

 (where any exist on the same axis), tristichous, i.e. with underleaves 

 added, even where absent from the rest of the plant, and in three, or 

 more, amplexicaul rows ; all cloven (usually bilobed, sometimes 3 — 5- 

 lobed) and very often toothed or subspinose ; cells elongate. Pistillidia 

 about 20, shortish and flaskshaped. 



8. Perianth free, usually very long and narrow, and elongato, re- 

 ticulate like the bracts, fusiform, trigonous — rarely with the angles vary- 

 ing from 3 to 5 or 6 in the same species, but, whenever reduced to 3, 

 with the third angle always postical; mouth truncate, but usually con- 

 stricted (from the angles becoming more pronounced and plicffiform at 

 the apex), variously toothed, ciliate, laciniate, or entire. 



9. Calyptra free (superior), with the sterile pistillidia surrounding 

 its base. 



10. Capsule on a long pedicel (which at the calceolate base buries it- 

 self deeply in the fertile branch), oblong or sub-cylindrical — usually 

 about twice as long as broad, but in the subgenus Cephaloziella often 

 shorter, oblongo-globose — 4-valved to the base ; capsule-walls of two layers 

 of cells, ivhereof the inner are strengthened by semiannular fibres. 



11. Elaters elongate bispiral, about as wide as the diameter of the 

 smooth or scaberulous spores. 



12. Propagula apical, minute, red or whitish, polyhedral or amor- 

 phous ; rarely present, except in a very few species. 



I divide Oeplialozia, as above-limited, into eight subgenera, as 

 follows : 



1. Peoto-Cephalozia 



2. Pteeopsiella 



3. Zoopsis 



4. Alobiella. 



5. Eu-Gephalozia 



6. Lembidium 



7. Odontoschisma 



8. Cephaloziella
