'''Gambeya lacourtiana''', commonly called '''Abam''', is a tropical African fruit tree in the family [[Sapotaceae]]. GBIF accepts ''Gambeya lacourtiana'' as the species name; ''Chrysophyllum lacourtianum'' and ''Chrysophyllum autranianum'' are associated alternative names.[[#cite_note-1|[1]]] Kew records the species as native to Cameroon, the Central African Republic, Congo, the Democratic Republic of the Congo, and Gabon.[[#cite_note-2|[2]]]

== Description ==

Abam is usually evergreen, with a spreading crown and a buttressed bole. It occurs in dense semi-deciduous forest and in sandy-loamy gallery-forest valleys. It can reach about 40 m in forest, a maximum that should not be treated as a prediction for a cultivated specimen.[[#cite_note-3|[3]]]

The fruit is harvested from the wild and sold in local markets. The tree is rarely planted, but it is commonly retained when forest is cleared for agriculture, giving it a semi-cultivated role in its native range.[[#cite_note-3|[3]]]

== Cultivation ==

=== Soil and water ===

The species grows in moist tropical settings with one or two dry seasons, including sandy-loamy gallery-forest valleys, and prefers a deep, rich loam.[[#cite_note-3|[3]]] As a habitat-level cultivation inference, provide a deep, fertile root zone that holds moisture through the dry season without losing the loose structure indicated by its gallery-forest habitat. A species-specific flooding tolerance and irrigation schedule are not established.

=== Sun and humidity ===

The native habitat includes dense forest, and seedlings need some shade.[[#cite_note-3|[3]]] As a habitat-level cultivation inference, establish young plants in bright filtered light with humid conditions before testing stronger exposure. Mature-tree tolerance of full sun outside the native forest environment is not established.

=== Seasonal changes ===

The native climate receives about 1,400–1,500 mm of annual rainfall and has a mean annual temperature near 24 °C, with one or two dry seasons.[[#cite_note-3|[3]]] As a habitat-level cultivation inference, keep the root zone more consistently moist as a dry season develops rather than treating the species as a drought-deciduous plant; it is usually evergreen.[[#cite_note-3|[3]]]

Young plants grow slowly, with an annual increase of only about 6–10 cm during the first three years.[[#cite_note-3|[3]]] This reported rate has no independent grower corroboration and should be treated as a planning indication rather than a fixed rate in every climate.

== Propagation ==

Sow ripe seed promptly. Germination may take up to six weeks, although some seed takes 50–100 days, and seedlings need some shade during establishment.[[#cite_note-3|[3]]] The wide reported interval makes a short germination deadline unsuitable for judging a seed lot.

Greenwood cuttings, air layering, and grafting are also named as propagation options, but their procedures and success rates are not quantified.[[#cite_note-3|[3]]]

== Flowering, fruiting, and harvest ==

Fruiting is regular or sometimes biennial, and fruit development to ripeness takes about 12 months.[[#cite_note-3|[3]]] Flowering can coincide with brief leaflessness during the short dry season.[[#cite_note-3|[3]]] No species-specific harvest index or flowering calendar is established beyond these observations.

The fruit is an apple-shaped berry about 6–11 cm long, dark red to light orange, and may contain up to five large seeds.[[#cite_note-3|[3]]]

== Fruit and uses ==

Abam has juicy, sticky pulp with a sweet to subacid flavor.[[#cite_note-3|[3]]] The fruit is eaten raw: a hole may be made in one end and the flesh sucked out. The pulp is also salted and eaten with cassava and plantain, and the fruit may be dried or used in sauces.[[#cite_note-3|[3]]] These are documented traditional uses, not a complete toxicology or food-safety assessment.
