'''Umbu-cajá''' ('''''Spondias bahiensis''''') is a fruit tree of Bahia, Brazil, in the family [[Anacardiaceae]]. The name umbu-cajá is also used for a distinct northern taxon, so the scientific name and regional provenance matter when comparing plants or fruit records.<sup>[[#cite_note-1|[1]]]</sup><sup id="cite_ref-2">[[#cite_note-2|[2]]]</sup><sup>[[#cite_note-3|[3]]]</sup>

Habitat records span wet-tropical and Brazilian semiarid descriptions: Bahia is listed in a wet-tropical biome, while the species is also described as native to Brazilian semiarid areas. Cultivation should therefore be matched to the plant's documented provenance rather than treated as evidence for one universal climate regime.<sup>[[#cite_note-1|[1]]]</sup><sup>[[#cite_note-6|[6]]]</sup>

== Description ==
''Spondias bahiensis'' is associated with managed cultivation in northeastern Brazil and is maintained for its juicy fruit. The 2015 taxonomic study described the southern Bahia lineage after comparing morphology, morphometrics, chloroplast DNA, and nuclear ETS data with related Spondias; later genomic studies likewise support a hybrid or introgressed history, although their sampled taxa and parental interpretations differ.<sup>[[#cite_note-2|[2]]]</sup><sup>[[#cite_note-3|[3]]]</sup><sup>[[#cite_note-4|[4]]]</sup>

The shared vernacular name creates a practical identification hazard. Records labelled only umbu-cajá may combine the Bahia species with a northern taxon, and fruit or cultivation observations should therefore be tied to a verified accession or regional identity.<sup>[[#cite_note-2|[2]]]</sup><sup>[[#cite_note-3|[3]]]</sup>

== Cultivation ==
Habitat records span wet-tropical and Brazilian semiarid descriptions, so no single moisture regime should be treated as universal. Begin with warm conditions, regular attention to water during establishment, and a medium that drains; match irrigation and exposure to the plant's provenance rather than transferring a congener's climate limits.<sup>[[#cite_note-1|[1]]]</sup><sup>[[#cite_note-2|[2]]]</sup><sup>[[#cite_note-6|[6]]]</sup><sup>[[#cite_note-7|[7]]]</sup>

=== Soil and water ===
As a Spondias, and given the contrasting regional habitat descriptions, it is reasonable to begin with regular moisture during establishment and a medium that drains between irrigations; this is a genus-level inference rather than a measured soil prescription for ''S. bahiensis''.<sup>[[#cite_note-1|[1]]]</sup><sup>[[#cite_note-6|[6]]]</sup><sup>[[#cite_note-7|[7]]]</sup>

=== Sun and humidity ===
Because habitat descriptions differ, a bright site with protection from severe drying while young is a cautious genus-level starting inference; adjust exposure to the plant's provenance and avoid treating one exposure regime as a fixed species requirement.<sup>[[#cite_note-1|[1]]]</sup><sup>[[#cite_note-6|[6]]]</sup><sup>[[#cite_note-7|[7]]]</sup>

=== Seasonal changes ===
In a reproductive-biology study from the Recôncavo da Bahia, flowering occurred from September to December and fruiting from October to December; the reported interval from flowering to harvest was approximately 180 days under those study conditions. Keep water available through flowering and fruit development, but treat the calendar as regional rather than universal.<sup>[[#cite_note-6|[6]]]</sup>

== Propagation ==
Spondias bahiensis is propagated by seed and vegetative means. Its hybrid or introgressed background and the value placed on fruit traits make vegetative propagation the safer choice when the goal is to retain a selected tree's identity and fruit characteristics.<sup>[[#cite_note-3|[3]]]</sup><sup>[[#cite_note-4|[4]]]</sup> The Embrapa Spondias germplasm programme reports vegetative propagation of most accessions, but its mixed-taxon bulletin does not provide a species-specific cutting, grafting, or seed-germination protocol.<sup id="cite_ref-7">[[#cite_note-7|[7]]]</sup>

== Flowering, fruiting, and harvest ==
The flowers include hermaphrodite and staminate forms. In the Recôncavo study, anthesis began around 4 a.m., stigma receptivity coincided with anthesis and lasted more than 24 hours, and bees were the main floral visitors. The study found self-incompatibility, preferential allogamy, and a tendency toward self-sterility; a lone tree should therefore not be assumed to set a dependable crop without compatible pollen and pollinator activity.<sup>[[#cite_note-6|[6]]]</sup>

The same study recorded flowering from September through December and fruiting from October through December under its local conditions. It reported approximately 180 days from flowering to fruit harvest, so harvest timing should be linked to the local flowering cycle rather than copied as a universal calendar.<sup>[[#cite_note-6|[6]]]</sup>

== Fruit and uses ==
The fruit is eaten fresh and is also processed. In a 2026 Research Square preprint based on 30 plants in one orchard at Currais Novos, Rio Grande do Norte, fully yellow stage-IV fruit averaged 22.58 g, measured 62% pulp, and had 13.0% soluble solids; that stage was judged most suitable there for fresh consumption and processing. These measurements are one-orchard preprint results, not fixed values for every accession.<sup>[[#cite_note-3|[3]]]</sup><sup>[[#cite_note-5|[5]]]</sup>
