Lindsaea sect. Pseudolancea
Content
Notes
L. parasitica is probably related to L. oblanceolata in sect. Odontoloma. But L. parasitica has bipinnate fronds on fully developed plants, whereas the fronds of all species of sect. Odontoloma are simply pinnate; the Separation of L. parasitica thus leaves a more clearly natural sect. Odontoloma. It seems probable that the bipinnate condition has arisen on more than one evolutionäry line within subg. Odontoloma; this subject will be further discussed elsewhere.
