September 23, 1964 - Nihoa Island 18
We land at approximately 9 a.m. The surf is high and we land with some difficulty on the rocky ledge at the outlet of east palm canyon.
We set up camp about 100 feet above the ledge in the dry stream bed. Some of the pot holes along this dry stream contain damp mud or an inch or two of water which supports a luxuriant bloom of algae. I walk up east palm gulch to Tanager Peak and about 200 yards east along the cliffs crossing west along the upper ridge of Tanager Peak. I then crossed the eastpalm gulch at its head and continued west along the crest of the north cliffs Sida sp. and Chenopodium are the most common species present on the upper and middle slopes with Portulaca caumii frequent on bare rock areas with soil pockets and Solanum nelsoni commonly found with Sida and Chenopodium. Pritchardia remota is found in the dry stream beds of east palm canyon and west palm canyon, and, at the base of sheltered cliffs - on the east palm canyon, and on the upper west side of west palm canyon. Portulaca lutea grows at lower elevations on the island but is infrequently found on the high rock ledges with P. caumii. I collected lichens (2 sp.) and Rumex on the north face cliffs near the summit of Tanager Peak. These cliffs fall nearly shear 300 feet into the sea except for pockets and chimneys in the cliffs which afford a soil pocket for plants and a handhold for the botanist. The Rumex was sterile at this time. Panicum tar ridum is common on the upper slopes, and, like Eragrostis is in flower and fruit. Both Sesbonia and Tribulus were found - both much flattened and dry - on the south side of the cliff faces.
