espinho-de-santo-amaro

The cockspur vine (Pisonia aculeata) is a scrambling, often aggressively spiny liana or shrub in the family Nyctaginaceae — the four o'clock family — distributed pantropically in coastal and lowland thickets, forest edges, mangrove margins, and disturbed vegetation across the Americas, Africa, and Asia-Pacific, with documented occurrences in Brazil, Colombia, Mozambique, and Taiwan among many other countries. The plant is named for its hooked spines, which anchor it to neighbouring vegetation and enable it to climb and sprawl across host shrubs and trees, sometimes smothering them. Leaves are simple and opposite; flowers are small, inconspicuous, and unisexual, produced in branched clusters. The sticky fruits of the related genus Pisonia — particularly P. grandis and P. brunoniana — are notorious for entrapping and killing small seabirds in nesting colonies, but P. aculeata's fruits are less dramatically adhesive. The plant colonises disturbed coastal vegetation, roadsides, and secondary growth readily, and can become invasive in some regions outside its native range. It tolerates salt spray and is characteristic of coastal scrub and tropical dry forest ecotones. Some traditional uses have been recorded for leaf preparations. Pisonia aculeata is classified as Least Concern by the IUCN, reflecting its wide pantropical distribution and tolerance of disturbed habitats, though it is seldom abundant and its ecological role in intact native communities is that of a minor woody climber.

Cole's Wattle

<em>Acacia colei</em>, commonly known as Cole's Wattle, is a tree or shrub in the family Fabaceae, subfamily Mimosoideae. The species is assessed as Least Concern on the IUCN Red List, indicating that it is not currently at elevated risk of extinction. It is documented in Kenya and Tanzania, where it is associated with tropical and subtropical grasslands and savannas within the Afrotropic realm. Like many acacias, <em>Acacia colei</em> is likely adapted to seasonally dry conditions, which are characteristic of the East African savanna ecosystems it inhabits. Members of the genus <em>Acacia</em> often play important ecological roles, providing shade, food, and habitat for a range of animals, and some fix atmospheric nitrogen through symbiotic associations with soil bacteria. Diet, population estimates, and biological measurements including length, weight, and lifespan are not specified in available data for this species. Biological traits of this species remain poorly documented in the scientific literature. Its Least Concern status reflects a relatively stable population in East African savanna landscapes.
