Habitat & Geographic Range

cloud-borne aloe

Habitat

Typically found in grasslands, wetlands, forests, and cultivated landscapes.

Rafflesia

Habitat

Found across multiple habitat types including tropical and subtropical moist broadleaf forests, tropical and subtropical dry broadleaf forests, and tropical and subtropical grasslands and savannas, among 5 distinct biome types spanning the Australasia and Indomalayan realms. Populations are also found in montane and highland environments at higher elevations.

Range

Distributed across Indonesia and Malaysia. Currently classified as Endangered on the IUCN Red List, this species faces significant conservation challenges across its range.

cloud-borne aloe

Cloud-borne aloe refers to an Aloe species native to high-elevation montane habitats in eastern or southern Africa, adapted to the misty, cloud-shrouded conditions of afromontane forest margins and rocky highland slopes. Aloe species at altitude typically experience different rainfall patterns, lower temperatures, and higher UV radiation than their lowland relatives, driving adaptations in leaf chemistry, water storage capacity, and root architecture. High-altitude aloes often produce rosettes with thick, succulent leaves containing gel-rich mesophyll tissue for water storage, adapted to both the seasonal dry periods and the fog drip typical of cloud forest margins. Many montane African aloes are important nectar sources for sunbirds and other highland bird species that serve as their primary pollinators. Several cloud forest aloe species face threats from habitat loss as montane forests and grasslands are converted to agriculture, combined with overcollection for the traditional medicine trade and for horticultural markets, contributing to conservation assessments of Vulnerable or Endangered for several highland Aloe taxa.

Rafflesia

Rafflesia arnoldii produces the world's largest individual flower, up to 1 meter in diameter. It is a parasitic plant with no roots, stems, or leaves.
