  • Discussion

    Lectotype (chosen by R. Tryon, 1955: 34). Brazil. Praia de San Diego, 1821, Sello s.n. (B, frag. NY!). Selaginella sellowii is distinguished from S. wrightii and S. landii by its glabrous leaf bases and long white awn, and from S. sartorii by the less imbricate leaves, not pubescent at their base in S. sellowii.
