Clustered clover

Trifolium glomeratum, the clustered clover, is an annual herb in the family Fabaceae native to the Mediterranean region, including southern Europe, North Africa, and southwestern Asia. Like other clovers, it has trifoliate leaves and produces small, globe-shaped flower heads composed of numerous tiny pink to purplish-pink pea-type flowers. The specific epithet glomeratum means 'clustered into a rounded mass,' referring to the tightly grouped flowerheads that remain sessile (stalkless) amid the upper leaves. The species grows in dry, disturbed ground, sandy fields, roadsides, grasslands, and coastal areas where soils are thin and nutrient-poor. T. glomeratum has been widely naturalized outside its native range, particularly in Australia, New Zealand, South Africa, and parts of North and South America, where it can become a common weed of agricultural margins and waste ground. Like all clovers, it fixes atmospheric nitrogen through root nodule bacteria, contributing to soil fertility. It has not been formally evaluated by the IUCN for conservation status. The species is palatable to livestock and may be grazed where abundant.

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.
