What is "christensenia"

''For the broad-nosed weevil genus, see '' Christensenia (beetle).

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.

Christensenia is the scientific name of two genera of organisms and may refer to:

• Christensenia (beetle) Brinck, 1945, a genus of beetles in the Curculionidae family
• Christensenia (plant), a genus of ferns in the Marattiaceae family
• Christensia Dózsa-Farkas & Convey, 1997, a genus of oligochaete worms in the Enchytraeidae family, and a junior homonym of Christensenia Brinck, 1945, replaced by Christensenidrilus

Christensenia is a genus of weevils in the Curculionidae family.
