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 Solanum nelsoni , Tribulus , Boerhavia , 
i 
and Sicyos . The extent of these patches varies with location and season.' 
Solanum nelsonl is especially dominant on the southern side and Tribulus 
on the north. Tribulus and Sicyos are mixed with Solanum nelsoni on the 
southern two-thirds, and Tribulus and Boerhavia are mixed with S. nelsoni 
v . * 
on the northwestern side,, A northern area dominated by Tribulus has one 
4 
patch of pure Sicyos and a larger patch of Eragrostls. A second clump of 
this grass grows further east in the £3. nelsoni - Tribulus - Sicyos associa¬ 
tion. Several very stunted Scaevola taccada bushes grow along the margin 
between the vegetated area and the beach on the southwestern and southern 
sides of the eastern section. 
Other plant species recorded in small numbers for Southeast are 
Setaria verticillata, evidently introduced in 1961 (KDFG, 1961); Lepturus 
repens ; Portulaca lutea ; Malvastrum coromandelionum ; and Casuarina 
equisetifolia, introduced in 1963, mostly dead in 1965, and absent in 1969. 
^ The photographs of Frear (Figure ), taken in December 1912, in¬ 
dicate that the flora of the island was chiefly tall bunchgrass, presum- 
ably Eragrostis . Eleven years later, in April 1923 , the photographs of 
Wetmore show the island to have a moderate, open cover of Eragrostis 
(Figure ). Sesuvium grew abundantly on the large reef rock ledge (Figure

). The Tanager Expedition collected six species on Southeast Island 
(Christophersen and Gaum, 1931:15-16)• Eragrostis and Lepturus were dis¬ 
tributed indiscriminately on the island. Sesuvium grew on the reef rock
