The S. obovata, Hook.f. and Tayl, corresponds with 

 what is understood as the fertile state of 6". rhizobola, 

 the attenuations of the apices of the divisions of the 

 fronds being absent. The specimens gathered by Dr. 

 J. D. Hooker are finely in fruit, and the fertile stems 

 are mixed with others corresponding in structure, but 

 differing in habit, being prostrate and rooting at the 

 apices, like the plants figured in Musci Exotici. See 

 note Fl. Tasm. ii., 239.
