Abstract
During the month of July 1974, various growth parameters were measured forUniola paniculata (sea oats) andAmmophila breviligulata (American beach grass), plants on the dunes of east- and south-facing beaches of Cape Hatteras. The data were grouped based on the exposure and aspect of dunes studied. ForUniola, height of the flowering culm, number of flowering culms/m2, and the height of leaves of non-flowering plants were the most diagnostic parameters. ForAmmophila, the height of the leaves of non-flowering plants was diagnostic. Generally, theUniola plants on the foredunes were taller than those on the backdunes. Plants growing on the southfacing beach were taller than their counterparts on the east-facing beach. On the southfacing beach, the side of the dunes which faces away from the ocean had the taller plants. On the east-facing beach, the side facing the ocean tended to have taller plants. ForAmmophila, the tallest plants were on the back portions of overwash areas. The next tallest occurred on the front of overwash sites. TheAmmophila plants on the ocean side of the dunes were taller than the plants on the back side of the dunes.
