Suaeda maritima ssp. richii, or herbaceous sea-blite, is an annual member of the Amaranth family. It grows prostrate along the ground, forming dense, highly branched mats up to 2½ feet wide. It has skinny, succulent leaves that range between ½ and 2 inches long. It has small (approximately 1/10th of an inch wide), red or green flowers and produces even smaller seeds. Suaeda maritima ssp. richii is easily confused with another introduced variety of S. maritima, Suaeda maritima ssp. maritima. S maritima ssp. richii has smaller seeds and shorter leaves than ssp. maritima. Suaeda maritima ssp. richii is found in salt marshes, beaches and intertidal zones along the Northeast coast of New England, USA and Canada. It is of conservation concern due to its limited range, and because it tends to be rare where it occurs.
