A New Variety of Pandamis and a New Species of Fimbristylis 
from the Central Pacific Islands. Pacific Plant Studies No. 11^ 
Harold St. John^ 
INTRODUCTION 
Since 1945 the writer has made three ex- 
peditions to the small islands of the Central 
Pacific. The first, in 1945, was backed by the 
University of Hawaii; the second, in 1946, by 
the University of Hawaii and the Pacific 
Science Board; the third, in 1949, by the 
Donaldson Expedition of the Atomic Energy 
Commission. On these trips a number of 
novelties were collected which are worth 
putting on record.
