Sept ember 17, 196 4 - Southeast Island 
The soil of the pool depression located on the east half of the 
island is dark with humus, wet and the parent material is coral sand 
and gravel. The Hawaiian monk seal is present with patches of epiphytic 
green.algae. Turtles are also found on the north shore of the island. 
Collections of drift algae and algae in situ on rocks were made. Soil 
samples, cytological material of Bo erhaavia and Scaevola preserved 
materials were secured. On Southeast Island Boerhaavia appears to be a 
pioneer on coral gravel bars. Tribulus is associated with Boerhaavia 
in these bare areas. Eragrostis is found in bare gravel on the outer 
parts of the island as well as on the interior. Seedlings of Sesuvium 
were seen in bare soil of the central depression which appear to be 
former booby or albatross rest sites. 
15* Messersehmidtia - one small plant on the north share of the 
east portion of the island on the west portion of the Southeast Island 
dead stems of a crucifer were found (to 4o inches in length). No live 
plants or seedlings were present. One Casuarlna seedling was uprooted.
