Radula jonesii

Radula jonesii is a species of liverwort in the family Radulaceae, first described in 1988 from specimens collected in the Anaga Mountains of Tenerife. Endemic to Macaronesia, this dark to olive-green liverwort is known from five locations on Madeira Island and one location on Tenerife, where it grows as both an epiphyte on trees such as Laurus novocanariensis and as a lithophyte on shaded rocks in old growth laurel forest ecosystems between 800–1,000 m (2,600–3,300 ft) altitude. The species is distinguished by its procumbent growth habit, pinnately branched stems measuring 10–15 mm (0.4–0.6 in) in length, and distinctive cellular features including uniformly thin-walled leaf cells. Classified as Endangered due to its restricted range and small population size, R. jonesii faces threats from climate change, habitat degradation, and tourism pressure, though its habitat receives protection through various conservation designations including UNESCO World Heritage status....read more on Wikipedia.
