The flora is presently .[19651 dominated by ten species, two of which are 
introduced. Seventeen species have been found by the POBSP. One of these, 
an onion ( Allium sp.) growing on the refuse heap, was eradicated by the POBSP

in March 1965* • - - 
The central portion of the western section has a sparse flora of Solanum 
nelsoni , Coronopus didymus , Boerhavia diffusa , Tribulus cistoides , and Lepidium 
o-waihl ense . Several clumps of Eragrostis variabilis grow to a height of about 
three feet near the center of this area. 
- • * 
The ledge of reef rock extending southeastward from the western section 
has a large patch of Sesuyium portuiacastrum in its interior. 
A patch of Sesuyium also grows on the reef rock extension at the southwestern 
comer of the eastern section. 
« 
The area in and, adjacent to the tidal pools in the eastern half of the 
eastern section is dominated by a lush growth of Sesuvium . West of these pools 
is a large area dominated by Coronopus . A large patch of E. variabilis and a 
smaller one of Cynodon dactylon , presumably introduced, grow adjacent to each 
other in the center of the Coronopus area. A few plants of Sonchus oleraceus 
and Solanum nigrum grow among the Cynodon and Coronopus . 
Surrounding the Coronopus area on the north and west is a steadily expanding 
area dominated by an introduced mustard, Brassica campestris . The area also 
has some Cynodon and some Sicyos hispidus . From this central, heavily-vegetated 
area out.'to the beaches is a relatively open coral sand and rubble region with 
patches of £>. nelsoni, Tribulus , Boerhavia , and Sicyos . The extent of these 
patches varies with location and season. 3. nelsoni is especially dominant on 
the southern side and Tribulus on the north. Tribulus and Sicyos are mixed 
with the 3. nelsoni on the southern two-thirds, and Tribulus and Boerhavia are 
mixed with the S. nelsoni on the northwestern side. A northern area dominated
