Aeranthes

Aeranthes is a genus of orchids belonging to the subfamily Epidendroideae. These plants are native to the southwestern Indian Ocean region, primarily found on Madagascar and the Comoros Islands. The name Aeranthes is derived from the Greek words "aer" meaning air and "anthos" meaning flower, a reference to their often aerial or epiphytic growth habit.

Species within the Aeranthes genus are typically characterized by their monopodial growth, meaning they grow from a single apical bud, producing a continuous stem. Their leaves are often strap-like and arranged alternately along the stem. The flowers are usually pendulous and can be quite striking, often featuring slender, elongated petals and sepals. The labellum, or lip, is typically modified and can vary significantly in shape and size among different species, playing a role in attracting specific pollinators.

Aeranthes orchids are generally found in humid, tropical forests, often growing on tree branches or rocks. They prefer moderate temperatures and good air circulation. Many species are epiphytic, relying on the surrounding environment for moisture and nutrients. Their pollination mechanisms are diverse, with some species having adaptations for moth pollination due to their nocturnal fragrance. The genus is relatively small, with a limited number of recognized species, each often having a specific geographic distribution. Conservation efforts are important for some Aeranthes species due to habitat loss in their native regions.
