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.

Coffee

Coffee (Coffea arabica) is a woody shrub or small tree in the family Rubiaceae, native to the montane forests of Ethiopia and Yemen, where it was discovered and first cultivated before spreading globally to become one of the world's most economically important crops. Plants grow 2–10 metres tall in the wild but are typically pruned to 2–3 metres in cultivation, producing glossy elliptical leaves and clusters of fragrant white flowers followed by cherry-like drupes that ripen from green through yellow to deep red. Each fruit contains two seeds—the coffee beans—surrounded by layers of sweet pulp, parchment, and silver skin. Coffea arabica is a diploid tetraploid (2n = 44) that produces smoother, more aromatic coffee than its sibling species Coffea canephora (Robusta). Wild populations in Ethiopian highland forests represent an important reservoir of genetic diversity for the global coffee industry and are threatened by deforestation and climate change, which is altering the geographic suitability of arabica cultivation. Commercial plantations extend from Colombia, Brazil, and Central America through East Africa to India, Indonesia, and Vietnam. As a shade-tolerant understorey plant in its native montane habitat, Coffea arabica supports biodiversity in agroforestry systems. Despite its vast cultivation, wild arabica populations face significant conservation concern.
