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).

American (H). 



Near Colobanthus of the 

 Antarctic islands, tem- 

 perate South America, 

 and Australia (C). 



South American (H). 



Regarded by Gray as a 

 section of Phyllostegia. 



Belong to the tribe Prasias, 

 which is mostly Asiatic. 

 Two other species of 

 Phyllostegia recorded 

 from Tahiti and Pau- 

 motu Islands. 



American (H). 



Allied to Boehmeria, a 

 genus of Old and New 

 Worlds. 



Belongs to Melicope, an 

 Old World genus (IK). 



Malayan (H). 



Referred to Panax, an 

 Old World genus (IK). 



Malayan (H). 

 Pterotropia referred to 

 Heptapleurum of Old 

 World (IK). 



Approaches both Asiatic 

 and American types (C). 



American (C). 



Malayan (H). Genus 

 also in Malaya (IK). 



Near Psychotria, a genus 

 of Asia and America (H). 



Malayan (H). 



Referred to the Aus- 

 tralian Ptilotus(IK).

 (C) = Drake del Castillo's Remarques sur la Flore de la Polyne'sie. 

 (IK) = Index Kewensis. 



Note. — Probably Schumann's genus, Pteralyxia, should be placed in the later group ^see p, 154).
