As will be noticed several good bryologists unite G. conferta with 

 G. apocarpa, and with some reason as the differences are not very important, 

 still there are several which induce us to keep them apart. These are in 

 G. confeyta the small size and densely pulvinate habit of growth, dark green 

 leaves, with the apex plane and more minute reticulation, and nerve more 

 prominent at back, the orange rimoso-cribrose teeth, which are more fragile 

 and fugacious. 



Schimper's var. obtusifolia is only a form with blunt -pointed leaves, and 

 G. pruinosa may perhaps be regarded as the transition to the next species.

 lane., with short hair-points or muticous, the margin strongly revolute.
