Unverified, Doubtful, or Mistaken Reports. DF (Rose & Painter 6835, US, cited by R. Tryon, 1955, but not verified). Ver (Liebmann 2062, US, cited by R. Tryon, 1955, but not verified). Selaginella sellowii is distinguished from S. wrightii and S. landii by its glabrous leaf bases and long white awns, and from S. sartorii by the less imbricate, non-ciliate leaves.
