flagelliform ramuli with densely imbricated, nerveless ovato-lanceolate 

 leaves ; so far as we know it has not been detected in this country. 



Georgia Broivnii most frequently occurs on the upper surface of hori- 

 zontal fissures in sandstone rocks, and then the capsule is of course the 

 lowest part ; when found on the upright faces of rocks the seta stands out 

 horizontally or curves gently upwards. Creeping among the felt-like stratum 

 may also generally be found associated some of the smaller liver-mosses, as 

 Diplophyllum albicans, &c. 



Lindberg aptly compares the radical frondiform leaves to miraature 

 fronds of the elks-horn fern Playtycerium alcicorne.
