Thirteen species of vascular plants have been recorded and^L-oolle^edr™ 
from Lisianski Island, Vascular plants have been collected by the follow¬ 
ing: G. P. Wilder, May 1925; F. C* Sibley, June 1965; A. Young, August 1964; 
and C. R. Long, September 1964, These collections are housed in the United 
States National Herbarium (USNM), the B. P. Bishop Museum (BISH), and the 
University of Hawaii (UH). 
Gramineae 
Eragrostis variabilis (Gaud.) Steud. 
Wilder 5, 7 (BISH), Young 152 (UH), Long 2516 (UH). Found on most of 
the inner portions of the island commonly with Boerhayia and Ipomoea in 
the central open area and in open Scaevola thickets. Often in pure local 
stands above the beach. Seedlings common especially on sand mounds on the 
interior as the result of shearwater burrowing. 
Palmae 
Cocos nucifera L. 
Two trees on the east side were observed in 1964. 
Casuarinaceae 
Casuarina equisetifalia L. 
Sibley 100 (USNM), Young 155 (UH). Four trees were observed in 1964. 
One specimen was dead on the southwest side. Used as a perch by fairy terns, 
boobies, noddies and frigatebirds. 
Nyctaginaceae 
Boerhayia diffusa L. 
Sibley 101 (USHM), Young 13k (UH), Long 2321, 2324, 2328, 2336, 2350 
(UH). Found over most of the island. In Scaeyola thickets the stems grow 
oyer the surface of the lower shrubs. This species appears to be a pioneer 
in sandy areas. Flowers vary in color from a lavender-pink to white. 
Many seedlings observed in 1964,

Sesuvium portulacastrum L. 
Wilder 6 (BISH), Only one collection exists. It is possible that 
during the denudation of the island the sites on which this common species 
is usually found were drifted with sand thus closing the preferred ecological
