Lectotype (chosen by Proctor 1977: 95). Plumier, Traite´ Foug. Ame´r., pl. 86, 1705, illustrating a plant from Martinique.
Unverified, Doubtful, or Mistaken Reports. Tab (Becerra s.n., MEXU, cited by Pacheco, 1994, but not verified). Trichomanes crispum is similar to T. galeottii (q.v.). In T. crispum, stipes are non-alate, the proximal pinnae are stalked, and the rachises are non-alate for at least the proximal 1/2 of their length.
