CHAPTER XXIII 



the era of the non-endemic genera of flowering plants 



The Mountain Floras of the Pacific Islands as illustrated by 

 THE Non-endemic Genera 



The mountain-flora of Hawaii. — A third of it derived from high southern 

 latitudes. — An American element.— Compared with Tahiti and Fiji. — 

 Capacities for dispersal of the genera possessing only endemic species. 

 — Acasna, Lagenophora, Plantago, Artemisia, Silene, Vaccinium, &c. — 

 Capacities for dispersal of the genera possessing non-endemic species. — 

 Cyathodes, Santalum, Carex, Rhynchospora. — Fragaria chilensis, Drosera 

 longifolia, Nertera depressa, Luzula campestris. — Summary.

{continued) 



The Mountain-Floras of the Tahitian and Fijian Regions 



The mountain-flora of the Tahitian region, as illustrated by the non-endemic 

 genera, — Derived chiefly from high southern latitudes. — Weinmannia, 

 Coprosma, Vaccinium, Astelia, Coriaria, Cyathodes, Nertera depressa, 

 Luzula campestris. — The mountain flora of Rarotonga. — The mountain- 

 flora of the Fijian region, as illustrated by the non-endemic genera. — 

 Weinmannia, Lagenophora, Coprosma, Astelia, Vaccinium, Nertera 

 depressa. — The Fijian Coniferffi. — Dammara, Podocarpus, Dacrydium. — 

 Not belonging to the present era of dispersal. — The age of dispersal of the 

 Coniferae in the Pacific. — Earlier than the age of Compositae and Lobeliaceas.
