CAMPYL0STELE2E (Fig. 1). 



Characteristics of Sub-Order. 



The characteristics of this sub-order are obscure. Mr. Wilson places in it the 

 genus Brachyodus, but it appears to us that Brachyodus has more affinity with 

 Seligeria, and we therefore only retain in Campylosteleoz the genus CampylosteUum. 



Capsule (a) oblong-, its walls very thin, lid very long, awl-shaped (subulate) . 

 Seta very much bent (geniculate) . Peristome single, of sixteen lanceolate teeth, 

 connected at the base by a membrane ; at the upper part forked unequally. 

 Leaves (c) linear-lanceolate ; cells (areolae) very small at the apex, larger at the 

 base. Monoicous. Plants minute. 



Fig. 1. Campylostelium saxicola. 

 Bent Moss (c) . 



Colour. Dull green. 



Stems. Very short, tufted, sometimes branched in threes. 



Leaves (b) . Lanceolate-subulate; the nerve sharp at the back (keeled), twisted. 

 Capsule. Oblong, lid long, seta bent. Winter. 

 Locality. On sandstone rocks ; but rare. 



The only known species. The bent seta may at first cause it to be mistaken 

 for a species of Campylopus, with which also the calyptra and peristome have an 

 affinity. It may ultimately be removed to that order. 



SELIGERLELE (Figs. 2-11). 



Characteristics op Sub-Order. 



Capsule nearly erect, roundish. Peristome wanting in some cases, when present 

 single, of cloven teeth. Leaves lanceolate, nerved ; plants small. 



This sub-order again is involved in much obscurity. We have removed 

 to it from Dicranece the genera Stylostegium and Blindia.
