NEED IN SITU PHOTOS. From 1919 to 1936, nine specimens of Suaeda nigra were collected from the Upper Basin, most by Frances Ramaley. Ramaley’s voucher specimens at the University of Colorado Herbarium have been certified as S. nigra by Dina Clark (personal communication). Although Watershed records would lie on the eastern edge of the USA distribution, probably S. nigra still grows in the Watershed. It is an extremely variable plant, and its less shrubby forms can be difficult to tell from S. calceoliformis, sometimes requiring dissection of the leaves. Suaeda nigra is the common seepweed of New Mexico, and it is present in the Rio Grande drainage to just beyond the Big Bend country of Texas, with scattered observations as far as the Gulf of Mexico.
