Coast Myall

Coast myall (Acacia binervia) is a small to medium tree or tall shrub in the family Fabaceae, native to coastal and near-coastal regions of New South Wales and Queensland in eastern Australia. It grows in coastal heath, dry sclerophyll woodland, and scrubby vegetation on sandy or rocky substrates, often in association with banksias and eucalypts. Like most Australian wattles, coast myall produces phyllodes—flattened leaf-stalks functioning as leaves—rather than true compound leaves in mature plants. The dark green phyllodes are distinctive, with two main veins, giving rise to the species name binervia. Golden-yellow, spherical flower heads are produced in winter to spring, attracting native bees. The genus Acacia sensu lato encompasses hundreds of species across Australia and globally, many of which play important ecological roles in nitrogen cycling through root symbioses. Coast myall is assessed as Least Concern by the IUCN. It is sometimes planted in coastal revegetation projects for its tolerance of poor, sandy soils, drought, and salt-laden winds.

Common Sensitive-Plant

<em>Mimosa pudica</em>, the common sensitive plant, is a pantropical annual or perennial herb in the family Fabaceae, order Fabales, native to South and Central America but now naturalized across tropical Africa, Asia, Europe, North America, Oceania, and South America. This species is best known for its rapid thigmonastic leaf movements — leaflets and petioles fold inward and droop within seconds of being touched or disturbed, a response thought to deter herbivores and reduce water loss. <em>Mimosa pudica</em> typically grows as a sprawling, prickly herb in disturbed habitats including roadsides, pastures, and degraded lands, and produces small pink to purple spherical flower heads. The seeds are dispersed via various vectors and germinate readily, contributing to its success as an invasive species in many regions outside its native range. The species is listed as Least Concern by the IUCN, reflecting its wide distribution and high adaptability. Biological traits for this species remain poorly documented in the scientific literature in terms of standardized averages for lifespan, plant height, and weight, though its growth habit and ecological behavior as a pioneer and potential invasive are well characterized.
