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.

Common teatree

<em>Leptospermum petersonii</em>, the lemon-scented teatree, is a shrub or small tree in the family Myrtaceae, native to eastern Australia but noted in distribution records including the Democratic Republic of Congo and the United States, reflecting its cultivation and occasional naturalization in tropical and subtropical regions. It is classified as Least Concern on the IUCN Red List. The plant is prized for its strongly lemon-scented foliage, which yields an essential oil used in perfumery and aromatherapy. It typically grows as a dense, multi-stemmed shrub reaching 3–6 meters tall, bearing small, narrow leaves and white or pale pink five-petaled flowers. Like other teatrees, it is adapted to well-drained, often nutrient-poor soils and full sun conditions. The flowers attract bees and other pollinators. It is sometimes cultivated as an ornamental and for essential oil production. Biological traits such as precise lifespan, seed output, and biomass measurements remain poorly documented in standardized scientific assessments for this species.
