OTHER HAWAIIAN ENDEMIC GENERA 



263 



by frugivorous birds is that only the hard-coated seeds propagate 

 the plant in a new locality. When, however, as has occurred in 

 the Hawaiian Islands, bird-agency largely ceases to act, this 

 selective influence is removed (see Note 68). 



ENDEMIC HAWAIIAN GENERA, EXCLUDING THOSE OF THE COMPOSITE AND 

 LOBELIACE-dE, AS GIVEN IN HILLEBRAND'S " FLORA OF THE HAWAIIAN 

 ISLANDS.' 



[Those preceded by * are not usually regarded now by botanists as endemic, though they nearly 



take that rank.] 



THE EARLIER GROUP. 



(H) = Hillebrand's Flora of the Hawaiian Islands. 

 (C) = Drake del Castillo's Rentarques sur la. Flore de la, Polynesie. 

 (IK) = Index Kewensis. 



NOTE. Probably Schumann's genus, Pteralyxia, should be placed in the later group (.see p, 154).
