cohune palm

The Cohune Palm (Attalea cohune), also known as the Corozo or Manaca Palm, is a large, solitary feather palm in the family Arecaceae, native to the lowland forests and forest margins of Central America, from southern Mexico through Belize, Guatemala, Honduras, El Salvador, Nicaragua, and Costa Rica. It produces enormous pinnate fronds up to 10 metres in length and stands 10–20 metres tall, dominating the forest canopy in areas where it occurs. The cohune palm is among the most useful wild palms of Mesoamerica: its large fruits yield a hard-shelled nut containing cohune oil, a white semi-solid fat historically used for cooking, soap manufacture, and as a cosmetic. Palm hearts from young plants are edible; fronds are used for thatching traditional dwellings; and the hard endocarp shells serve as fuel and for crafting buttons and ornaments. The species grows abundantly on deep, humid soils in forest and successional habitats, and its density is often used as an indicator of high-quality agricultural soils by local farming communities. The IUCN classifies Attalea cohune as Endangered, reflecting historical deforestation and ongoing land conversion across its Central American range. Despite this listing, it remains locally common in some areas and shows some resilience in secondary forest.
