Jensenia
Jensenia is a bryophyte plant genus in the liverwort family Pallaviciniaceae. It has been treated as a subgenus of Pallavicinia by several authors, though a set of features seems to set it apart as a genus. The six or seven species of the genus belong to a southern, possibly Gondwana element.〔 ==General characteristics== Jensenia liverworts are dioicous. Compared to Pallavicinia liverworts,〔 their thallus grows erect, and branches tree-like, rather than trailing the ground. The thallus is perched on an ascending stipe which grows from a creeping rhizome. Slime papillae are absent from the thallus margin, though locally present elsewhere. The midrib of the thallus is broad but ill-defined.
