The carpels, at first nearly or quite se ile, become elevated on slender spiral ly twisted pedicels radiating from a long peduncle, each making in fruit an obliquely ovoid truncate nutlet with fleshy surface. The only certain species, R. maritima , known in America as ditch - gra , in Great Britain as ta el gra , etc., is one of the very few flowering plants of marine waters, and is found throughout temperate and subtropical regions in salt-marshes, brackish ditches, and inlets of the sea. It grows in submerged tufts of thread-like forking and wiry stems from a filiform rootstock. It bears opposite and alternate leaves, which are long and bristle shaped with a sheathing base, and inconspicuous flowers, usually two, in a terminal spike, at first covered by the sheathing leaf. ruptile (rup'til), a .
