number of ferns recorded for any single state is not far 
from eighty, and for the whole United States, the number 
is about two hundred. 
Think then of finding upon a single mountain more 
than two fan and fifty species, for that is the num- 
ber Dr, E. B. Copeland records in his recent paper. 
Think of finding on a single mountain thirty-three kinds 
which had not been found anywhere else! Fifteen of 
these are described for the first time in the paper under 
consideration. As only a few botanists have collected — 
on Mt. Apo, it is likely that more will be foun 
Mt. Apo is the highest mountain in the Philippinge: 
_ It is situated in southeastern Mindanao on the west side _ 
of the long Davao Bay, and rises to a height estimated _

— to twenty miles in diameter. : 
_ As Dr. Copeland notes, “Every botanical collector _ 
knows that he can make his richest collections on and 
about high mountains.” He suggests that with its more 
than two hundred and fifty species, Mt. Apo is the rich- 
est in fern species of any known area of similar size. It 
would be interesting to make careful count of the number _
