Brosimum alicastrum, commonly known as breadnut, Maya nut or ramon, and many others, is a tree species in the family Moraceae of flowering plants, whose other genera include figs and mulberries.

Two subspecies are commonly recognized: Brosimum alicastrum can be monoecious, dioecious or hermaphroditic, changing from female to male as they age.

Large stands occur in moist lowland tropical forests at 300–2,000 m (980–6,560 ft) elevation (especially 125–800 m),[clarification needed] in humid areas with annual rainfall of 600–2,000 mm (24–79 in), and average temperatures of 24 °C (75 °F).

Breadnut may have formed a part of the diet of the pre-Columbian Maya of the lowlands region in Mesoamerica,[7][8] although to what extent has been a matter of some debate among historians and archaeologists: no verified remains or illustrations of the fruit have been found at any Mayan archaeological sites.

[8] Puleston demonstrated a strong correlation between ancient Maya settlement patterns and the distribution of relic stands of ramon trees.

[11] A high density of seeds during the seedling[clarification needed] offsets a reduced viability of the young plants and therefore enables a good yield.

The fresh seeds can be cooked and eaten or can be set out to dry in the sun and roasted and milled into a chocolatey tasting powder.

It can therefore undertake a bacterial-fungal endosymbiosis which assists the oxalate-carbonate pathway (OCP) and especially the chemical reaction of biomineralization, and in this case biocalcification (to produce CaCO3 from CO2 and to store it in the soils).

Furthermore, its oxalogenic activity increases the pH and the amount of organic matter in the soil once well implemented[clarification needed] in the agricultural system.

[22] The plant is known by a range of names in indigenous Mesoamerican and other languages, including: ojoche, ojite, ojushte, ujushte, ujuxte, capomo, mojo, ox, iximche, masica in Honduras, uje in the state of Michoacan Mexico, mojote in Jalisco, chokogou in Haitian Creole and chataigne in Trinidadian Creole.
