Description
editNothofagus macrocarpa is a tree growing 4 to 10 meters tall. It has a stout trunk, either single or with two or three growing from the base. The bark is rough and grayish brown with longitudinal and transverse cracks. It has a leafy and densely-branched crown 3 to 5 meters wide. Leaves are bright green and wavy at the edges, typically oval, and measure 13 to 45 mm long by 7 to 23 mm wide.[3]
Range and habitat
editNothofagus macrocarpa grows at higher elevations of the Altos de Cantillana, in Melipilla Province southwest of Santiago, at approximately 2,200 meters elevation.[3] It is also found to the east in the Andes foothills of Cachapoal Province from 500 to 2,000 meters elevation.[1]
Populations on Cerro El Roble and other nearby mountains once identified as N. macrocarpa were reclassified in 2000 as a distinct species, Nothofagus rutila.[3]
Classification
editIt is sometimes regarded as a subspecies of Nothofagus obliqua.[4] In 2013 Heenan and Smissen proposed renaming N. macrocarpa to Lophozonia macrocarpa.[5]
