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.
