Cephalozia catenulata var. pallida {Ceph. pallida nobis in hb.), Spruce, On 

 Cephalozia. (1882.) 



Dioicous, cladocarpous, depresso-csespitose, eflagelliferous, small, 

 pale green to yellowish in colour. Stems much branched, branches 

 subfastigiate ; cortical cells 15, rather larger than the inner ones, 

 5, 6 cells in diameter. Leaves small, approximate, from patent- 

 divergent to erecto-patent, orbicular to oval-rotund, subdecurrent, 

 from a third to the middle bifid, rarely more, sinus obtuse, seg- 

 ments acute or obtuse, connivent ; cells smallish to medium in 

 size, subquadrate, walls thick, no trigones or thickened angles. 

 Stipules wanting. Bracts larger than the leaves, oval-rotund, 

 bifid to a third, segments acute or obtuse, margin entire, bracteole 

 similar, sub-bracts and sub-bracteole similar but much smaller. 

 Perianth projecting much beyond the bracts, linear-fusiform, 

 composed of a single layer of cells, obtusely trigonous, mouth 

 ciliolate or setulose, ciliola 2 cells long. Calyptra moderately 

 coarse; pistillidia few, 8-10. Capsule oval, dark-brown. Spores 

 pale yellow. Elaters slightly broader and of a darker colour, 

 loosely bispiral. A ndroecia on short postical branches ; perigonial 

 bracts closely imbricate, erect, oval-rotund, concave, bifid to about 

 a third, with usually a third smaller tooth near the middle, seg- 

 ments acute ; antheridia oval.
