Other fruits noted were oranges, mangoes, papayas, guavas and 
others less frequent. 
. Trips were made to Hawaii and Kauai, respectively the most 
southerly and most northerly islands of the group. 
Attention was drawn to the great difference in the amount of rain- 
fall upon different parts of the islands, especially upon the two sides 
of Hawaii. At Hilo the annual rainfall is 180 inches, and the vegeta- 
tion in consequence extraordinarily luxuriant. Here the ferns reach 
wonderful development and the tree-ferns reach their full size and 
beauty. The ferns belong to much more diverse groups than in the 
United States, and all of the principal groups are represented. 
On Hawaii the largest forests trees were met, but the variety is 
much less than on Kauai, which is much richer, especially in flower- 
ing plants. 
The different geological age of the islands was referred to, Kauai 
being the oldest and Hawaii the youngest. Hawaii is, indeed, still 
in process of formation. 
The islands being so isolated, and never having been connected 
with any other land have developed a most peculiar flora. Of the 
flowering plants and pteridophytes together almost 75 percent. are 
strictly peculiar to the islands, while of dicotyledons the percentage 
is about 85, the highest known in any area of equal size.
