C., Tenn., Tex., Va. Eleocharis tortilis differs consistently from E. tuberculosa only in tubercle size. Most specimens of E. tortilis have culms that are

terete to elliptic in cross section, to 1.1(–1.5) mm wide. Eleocharis tuberculosa 47 Achenes pale gray or greenish when mature, clearly cancellate to honeycomb-reticulate

and waste places in the United States. It is generally similar to A. tuberculosa, but has shorter glumes, calluses, and awns. None. None. window.prope

spines, one above the other, both 3 mm, resembling immature Coryphantha tuberculosa except for subtleties of color, thickness, and orientation of the spines

species are more difficult to discriminate. Sympatric C. dasyacantha and C. tuberculosa are easily misidentified; identification without seeds or fresh flowers
