carried out on South Island, 
Below is a short summary of the vegetation of each large island 
and the other islet groups as observed in 1965* 
South Island , Old Cocos groves cover the greater portion of 
South Island, Interspersed in these old groves are thickets of 
Morinda often associated with Inoiaoea tuba. In some open areas 
where Cocos t3?ees have died or been felled by natural oaiises the 
grass Lepturus repens forms a nearly closed stand with Ipomoea , 
A Sxriana — Leptuarus zone forms a fringing association arovind 
South Island, On the north side bordering the lagoon the Sxriana 
forms a dense continuous shrub border (see Fig, 4»)» On the west, 
south and east sides the Suriana shrubs are taller, less compact 
and more scattered (see Fig, 3»), Patches of Lepturus are scat¬ 
tered about often extending well outside and beyond the Siiriana 
zone toward the high tide line. 
Hake Island , Like South Island Hake has been planted to Cocos , 
The groves extend the entire length of the island, (See Pig, 7 and 
Pig, 8,). In open patches of the interior and along the edge of 
the Cocos stands occur associations of Pandanus, Morinda and Tour— 
nefortia . Along the northeast side an almost continuous riming 
stand of Tournefoirfcia lines the area between the groves of Cocos 
and the open sandy beach with scattei^d clumps of Lepttirus and 
the ubiquitous Boerhavia repens . Some of the older Tovtmefortia 
trees may reach almost 3 meters high# In damp muck areas under the 
Cocos groves Taoca is found in scattered groups. 
Long Island . On the north end of Long Island are clumps of 
Morinda and Cordia , As one walks south along the lagoon edge of 
the island Pisonia trees are observed with Cordia and Morinda , 
(See Pig, 6,), On both sides of the island Tournefortia forms a 
fring with open areas supporting Leptxtrus in scattered bunches. 
On the south end of the island occurs an open area among Toxirne- 
fortia shrubs# Here in open sand was found the only Tribulus to 
be found on the entire atoll. On the north side lesser frigate—
