Plants on rock. Stems long-creeping, threadlike, bearing scattered leaves, covered with dark hairs of 2 types, 2-celled glandular hairs and elongate rhizoidlike hairs; roots absent. Leaves round to obovate, simple to irregularly lobed, 1–3 × 0.5–1.5 cm, with dark stellate hairs on margin, 2-celled glandular hairs on petioles and veins, and dark rhizoidlike hairs on petioles; petioles shorter than blades. Venation repeatedly forking from the base; unconnected false veins few or absent. Soral involucres 1–5 per leaf, terminal on blades, narrowly conic, not flaring at mouth; involucre lips with conspicuous dark marginal band 2–5 cells wide. Gametophytes unknown, presumed to be as others of subgenus. 2n = 68.
Habitat: On rock in limestone sinks
Elevation: below 10 m
Distribution
Fla., Mexico, West Indies, Central America, South America.
Discussion
Trichomanes lineolatum leaves have unusually thick veins that are enlarged toward the margin and conspicuous in dried specimens.
Selected References
None.
