Climbing cactus

Climbing Cactus 2 represents another species in the cactus family Cactaceae that adopts a scandent, climbing, or epiphytic growth form rather than the typically upright, succulent form associated with desert cacti. The evolution of climbing habits in cacti occurred multiple times across the family, primarily in tropical forest environments of the Americas where vertical forest structure provides opportunities for sun-seeking growth strategies. Epiphytic and climbing cacti include species in genera such as Rhipsalis, Lepismium, Disocactus, and Weberocereus, many of which produce pendant or scrambling stems adapted to clinging to bark and mossy tree surfaces in cloud forests and tropical lowland forests. These species often have flattened or cylindrical stems with reduced or absent spines, modified for life in humid, shaded forest environments. Flowers are typically small and numerous in the epiphytic genera, though some climbing ground-level cacti produce large, showy, nocturnal blooms. Several species are used in traditional medicine in their native range. The conservation status of individual climbing cactus species varies greatly; those restricted to threatened cloud forest or dry tropical forest habitats are of conservation concern, while others are widespread and adaptable.

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.
