SS INTRODUCTION. 
Species of Austral-Asiatic genera mostly single or few, constant 
on all islands with little variation. Many of them probably 
carried over by aborigines, as they served for food or for some 
purpose of domestic economy. 
Absence of Gymnosperms militates for the view that the 
islands were formed subsequent to the age in which these were 
universally distributed, Ferns having been prevalent in all 
periods 
Importance of the tropic bird (Phaéton phoenicurus) in the 
distribution of species; [also of] another migratory bird, the 
plover, which is known also on the coast of N. America.

The silvery white tomentum a character of high mountain 
plants: Argyroxiphium, Geranium, Raillardia struthioloides. 
he presence of resin in plants seems to be associated mostly 
with narrow and stiff nervate leaves. 
ww size of trees. None, excepting the Cocoanut palm, 
exceeding 100 ft. On Oahu trees are seldom over 50 ft., except 
in deep valleys of Kaala, where Kukui and Koa are seen of 
60—80 ft. height. Knudsen reports the <Alphitonia ponderosa 
as the highest (60 ft.) from Kauai. On Maui (Ulupalakua) and 
Hawaii high trees only on the leeward sides. 
Nearly all native plants perennial and woody. 
Few water plants; mistake of Engler in marking all Cyperaceae 
as such.

Ohia lehua — Ohia ai — Ohia. 
Is this indication of a beginning of generalization or classi- 
fication in the native mind — the word ohia being the general 
appellation for nearly related species? Or is the recurrence 
the > via in ohia ai owing to the circumstance that the 
latter tree was imported after the first settlement by men and 
after the indigenous trees had already received special names,
