INTRODUCTION. x VII 
with amazement at their daring and cannot help assuming that 
they then had a greater knowledge of astronomy than they were 
ound to possess at the time of the discovery of the group. It 
is not unlikely that the number of plants thus introduced is in 
reality much greater than has been assumed here. 
Deducting now the 115 species introduced by man since the 
discamaee and the 24 before that perio = there remain 860 species 
of Phanerogams and Vascular Cryptogams as original inhabitants 
species to one genus. Of these 860 species no less than 653 
are endemic, i. e., peculiar to the Islands, or 75.93 per cent., 
and of this number 250 species belong to 40 endemic or peculiar 
genera, with an average of 6.25 species to one genus. The 
proportion of endemic Phanerogams to original Hawaiian Phan- 
erogams is 574: 705, or 81.42 per cent. Restricting the 
computation to Dicoty ledons alone we arrive at the extraordinary 
mi of 500 : 384, or 85.62 per cent. of endemic Dicoty- 
ledon 
The great majority of endemic species inhabit a limited area, 
are confined to a samc island or portion of it. In some of the 
larger genera there are one or a few leading species which extend 
over the whole or ae part of the group, with only slight
