V. Eu-Fernandezian element. — i (1.9%). 

 Endemic genus without affinities among tlie living ferns: Tiiyrsopteris elegans. 



As could be expected, the Chilean element is stronger among the ferns than 

 among the angiosperms, followed in great distance by the neotropical, which also 

 is comparatively stronger, whereas the Magellanian and the Pacific are less im- 

 portant, especially the latter; long-distance advocates would expect the opposite, 

 because ferns ought to travel across the ocean much more readily than flowering 

 plants. 



III. Musci. 



The following list is based on Brotherus' paper in vol. II {^4) and on his 

 treatment of the group in the 2nd edition of NatiJrl. Pflanzenfam. In many cases 

 the figure for the number of species (in brackets) is too low, as numerous mosses 

 have been described in later years, but I have refrained from searching the litera- 

 ture. Much information was obtained from Herzog's work {i2g) and in pt. 2 of 

 Irmsciier's book [14-3). I am indebted to Dr. HERMAN Perssox for kind assistance.
