Fitzroya occurs as genus in the cypress family Cupressaceae with only one species, Fitzroya cupressoides native to the Andes mountains of central Chile and adjoining Argentina, where these are an crucial member of the Valdivian temperate rain forests. A scientific title of the genus honours Robert FitzRoy; common list include Lahuan (a Mapuche Native American name), Alerce (South American Spanish), & Patagonian Cypress.

These are the super big evergreen tree, the big tree mintage within South America, growing to 40-60 m tall & as much as Quint m trunk across. A leaves are in intersecting whorls of Three, 3-6 millimeter yearn (to Eighter from decatur millimeter yearn in seedlings) & 2 millimetre broad, marked using two whiten stomatal lines. A cones are globose, 6-8 millimetre through, opening flat to Dozen millimetre across, by owning nine scales around terzetto whorls of troika. Single a central whorl of scales is fertile, bearing Two-Three seeds on each shell; a lower berth & upper whorls come little & unfertile. the seeds come Two-Three millimetre hanker, flat, using a wing along every side. A seeds come matured 6-8 months when pollenation.

Around 1993 a specimen from Chile wwhen dated as 3622 years old. This gives it a 2nd-greatest fully verified age recorded for any dwelling tree (a oldest existence a Great Basin Bristlecone Pine). Great deal big specimens existed it used to be that prior to a coinage was heavy logged in the 19th & Twentieth centuries; Charles Darwin reported finding the specimen Dozen.Sextet m from side to side, which, whenever accurately measured, would stand mass produced it a stoutest tree ever measured anywhere in the globe.

a team of investigator from either the University of Tasmania found fossilized foliage of Fitzroya on the Lea River of northwest Tasmania. A 35 million season-old fossil has been given a mintage title Fitzroya tasmanensis. A searching for demonstrates a ancient floristic affinities between Australasia and southern South America, which phytologist identify when a Antarctic flora.
