Spondias L.

Mombin (en)

Genus

Angiosperms > Sapindales > Anacardiaceae

Characteristics

Trees, wholly or partly deciduous, rarely hemi-epiphytes. Leaves spiral, impari-pinnate, rarely bipinnate (extra-Mal.), or simple (extra-Mal.), petioled. Leaflets alternate, subopposite, or opposite, entire, serrate, crenate, or crenulate, in most spp. with a distinct and slightly thickened, intramarginal vein. Inflorescences paniculate, rarely racemiform, terminal and/or axillary, appearing before the leaves or accompanied by very young ones. Flowers bisexual, or unisexual (extra-Mal.). Calyx 5-(or 4-)lobed. Petals 5 (or 4), valvate, glabrous. Stamens 10 (or 8); filaments subulate or filiform, glabrous, or papillose (extra-Mal.); anthers dorsifixed. Disk intrastaminal, shortly cupular, or round and flat, crenulate, glabrous, or papillose (extra-Mal.). Ovary 5-(or 4-), or 1-celled, glabrous; styles 5 (or 4) and free, or 1; stigma(s) often shortly spathulate. Drupe 5-(or 4-), or 1-celled; endocarp woody, hard, sometimes almost bony when dry. Seed with testa free from the endocarp; embryo straight or slightly curved, cotyledons free, plano-convex.
More
Shrubs to large trees. Leaves odd-pinnate, often crowded toward the branch apex, deciduous, the leaflets alternate or opposite, membranous or subcoriaceous, petiolulate or rarely subsessile. Inflorescences paniculate to racemose or subcapitate, terminal or lateral, large or small. Flowers small, hermaphriditic or less often male or female, pedicellate or sessile; calyx-segment (4)5, small, deciduous, slightly imbricate; petals (4)5, erect to spreading or reflexed, subvalvate in bud; disc intrastaminal, cupular, crenate; stamens (4-)8-10, inserted below the disc; ovary 3-5-locular, the styles 3-5, connivent above but free (rarely united by their stigmas), a distinct stigmatic region apparent or not, the ovules solitary in each locule, apical. Fruit a fleshy drupe, 1-5-locular; seeds with a membranous testa.
Trees, usually deciduous. Leaves spirally arranged, clustered at branchlet tips, large, imparipinnate, with subopposite leaflets, rarely bipinnate or simple (not on Christmas Island); leaflets usually with a distinct intra-marginal vein; petiole much thickened at base. Inflorescence axillary or terminal, often forming a large panicle. Flowers small, actinomorphic, 5-or occasionally 4-merous, bisexual or unisexual. Calyx usually 5-lobed or divided. Petals usually 5, free, reflexed, valvate. Stamens 8 or 10, sometimes staminodal, inserted below disc. Disc annular, deeply 10-lobed, glabrous. Ovary 5-locular, each with 1 ovule. Styles 3–5. Endocarp 1–5-locular, woody, ridged, sometimes with many slender processes. Seeds usually 1–3. A detailed description is provided by Mitchell & Daly (2015: 14–15).
Entirely or partly deciduous trees. Leaves alternate, spirally arranged, petiolate, imparipinnately compound; leaflet margin serrate or entire. Inflorescence paniculate, terminal or axillary. Flowers 4-or 5-merous, bisexual or functionally unisexual. Stamens 8-10; filaments subulate to filiform, equal in length. Disk intrastaminal, 10-crenate to crenulate. Ovary 4-or 5-locular, with 1 ovule per locule; styles 4 or 5, free, or style 1. Fruit drupaceous; mesocarp juicy; endocarp woody or bony, covered by a fibrous matrix; embryo elongate, straight to slightly curved.

Usage

Uses. Cultivated for the edible fruit which is generally sour, though some varieties are sweet or have a mawkish taste; it is eaten, usually after cooking, as pickles or flavouring. All parts of the plants have a foetid smell of turpentine when broken or bruised; the smell differs in each species and is characteristic. The flowers are honey-sweet like those of mango. Hog-plum trees flower and fruit throughout the year, though chiefly after dry weather. The inflorescences develop at the ends of the bare twigs either before the new leaves or with them and the fruits dangle from the leafy twigs. Flower and fruit are generally to be seen together on the same tree ( CORNER Ways. Trees 1940 ).
More
Some species are widely cultivated for their fruit, which is often sour and eaten mainly as a pickle or a flavouring. Some species are also used in traditional medicines and are being been scientifically investigated for their potential medical uses, e.g. Spondias mombin. Economic botany is briefly covered by Mitchell & Daly (2015).
