Cockspur

Cockspur (Casearia aculeata) is a spiny shrub or small tree in the family Salicaceae, native to tropical and subtropical forests and thickets of the Caribbean, Central America, and northern South America, including Colombia, Cuba, and Brazil. The plant typically grows to three to eight metres in height, armed with paired stipular spines at the leaf axils that give rise to the common name. Leaves are alternate, simple, and glossy; small, inconspicuous flowers are produced in dense axillary clusters and are followed by small capsular fruits containing seeds with fleshy arillate coatings that attract birds, the primary seed dispersers. Casearia is a pantropical genus of around 160 species, many of which are important components of tropical dry and moist forests; C. aculeata is characteristic of disturbed and secondary vegetation, forest edges, thickets, and coastal scrub. The species has some traditional medicinal uses in its native range, with bark and leaf preparations employed in folk remedies for skin conditions and inflammatory complaints. Ecological studies of the genus indicate that Casearia species play important roles as pioneer and secondary succession trees, providing food resources for frugivorous birds and mammals. Casearia aculeata is classified as Least Concern by the IUCN, with wide distribution and no known major threats across its range. It is tolerant of moderately disturbed habitats and can regenerate in secondary vegetation.
