This fern was growing in Mr. W. S. Millard’s 
Fernery on Malabar Hill in 1918. How it 
came to be there Mr. Millard was at a loss to 
explain. He had certainly not cultivated it. 
Possibly some spores finding his fernery a 
congenial place for their development germi-

frond sent to the St. Xavier's College Museum

specimens of this fern in the Victoria Gardens. 
Distribution: Abundant on the Himalayas 
from Chumba to Bhotan, 3,000-8,000 feet; 
Khasya—Philippines, Java and Samoa.
