Taxonomy
The two paleotropical species share with the neotropical ones a short-creeping rhizome, a bipinnate lamina with conform terminal pinna, or a simply pinnate lamina, dimidiate pinnules, free veins, and continuous sori. The spores are trilete in most neotropical and both paleotropical species. Otherwise the resemblance is not close, in spite of much habitual similarity between L. borneensis Hooker and L. guianensis (Aubl.) Dryand., and between L. doryphora Kramer and L. lancea (L.) Bedd. It is not at all certain that the paleotropical species are of the same derivation as the neotropical ones.
