Eucephalozia 45 



Taylor calls the leaf-segments merely acute, yet liis own specimens sliowtliem dis- 

 tinctly apiculate, and this, along with the deeper sinus, the absence of flagella and 

 the dioicous inflorescence, aflords the most obvious differences from G. bictispidata ; 

 while the cladogeuous perichsetia separate it from C. Lammersiana.
