 offered to Chapter members, is of medium size and grows on the 

 soil and rocks; it somewhat resembles F. adiantoides Hedw., but 

 the leaves are usually more closely imbricated. F. obtiisijolius

 constituting with F. adiantoides Hedw., F. cristatus Wih. and F. 

 taxifolius Hedw., our most common species. F. osmtindoides
