Christensenia (plant)
''Christensenia'' is a genus of ferns in the botanical family Marattiaceae. The genus is confined to the Indo-Malayan region. The basal chromosome number for this genus is 2n=80. ''Christensenia'' is unique in the Marattiaceae, because of its reticulate venation, palmately arranged leaves and radial synangia. ''Christensenia'' produces enormous amounts of spores, up to 7,000 spores per sporangium. The presence of a radial synangium is an archaic character, very similar to some of the fossil Asterothecaceae/ Psaroniaceae, such as '' Scolecopteris''. ''Christensenia'' itself has no fossil record. Species After the 1993 revision by Rolleri, only two species A species () is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction.

They resemble small earthworms and include both terrestrial species known as potworms that live in highly organic Ecoregion#Terrestrial, terrestrial environments, as well as some that are Marine (ocean), marine.
