Clusterspike False Indigo

Amorpha crenulata, known as clusterspike false indigo or crenulate lead plant, is a critically endangered flowering shrub in the family Fabaceae with a highly restricted distribution confined to Miami-Dade County in southern Florida, USA. This species represents one of North America's rarest plants, with remaining populations numbering in the hundreds of individuals occurring in pine rockland habitat, an ecosystem itself ranked among the most imperiled in the United States. Pine rocklands are fire-dependent communities on exposed oolitic limestone, characterized by an open canopy of slash pine over diverse understory, and have been reduced to less than two percent of their historical extent by urban development in the Miami metropolitan area. Amorpha crenulata produces elongated spikes of small purple flowers typical of the genus and was historically more widespread across the Miami Rock Ridge before land development eliminated most habitat. Current populations exist primarily within Everglades National Park and a few private preserves. Its Critically Endangered status reflects the tiny remaining population, extreme habitat restriction, ongoing threats from urbanization, altered fire regimes, and sea-level rise that threatens low-elevation limestone habitats. Conservation efforts focus on habitat protection, controlled burning to maintain pine rockland structure, and ex situ seed banking.

Cockroach berry

The cockroach berry (Solanum capsicoides) is a spiny, semi-woody shrub in the family Solanaceae — the nightshade family — native to eastern Brazil but now established as an invasive or naturalised weed throughout the humid tropics, including parts of Africa, Asia, Australia, and the Pacific islands. Growing to about one metre in height, it is armed with sharp, straight prickles on stems, leaves, and even the calyx, making it unpalatable to grazing animals and difficult to control mechanically. The leaves are lobed and pubescent, resembling those of other weedy solanums, and the plant produces clusters of small white flowers with yellow anthers characteristic of the genus. The globose fruits, around two to three centimetres in diameter, are initially green with white marbling and ripen to orange or red; they superficially resemble small chilli peppers or tomatoes but are toxic to humans and most livestock, containing solanine and related steroidal alkaloids. Birds are primary dispersers of the seeds, facilitating the plant's rapid spread in disturbed habitats including roadsides, forest margins, degraded pastures, and abandoned agricultural land. Solanum capsicoides is Not Evaluated on the IUCN Red List, reflecting its status as a common, widespread, and spreading species rather than one of conservation concern. In its invasive range it can form dense monospecific thickets that suppress native vegetation.
