Acampe
Acampe is a genus of monopodial, epiphytic orchids native to tropical Asia and Africa. Known for their slow-growing, vine-like habit and thick, leathery leaves, these orchids produce small to medium-sized, fragrant yellow flowers with orange or red stripes. The genus name "Acampe" comes from the Greek word for "rigid," referring to their inflexible flowers.

About Acampe
Acampe, abbreviated as Acp in the horticultural trade, is a genus of monopodial, epiphytic orchids belonging to the Vandaceous group. These plants are distributed across tropical Asia, with populations found from India eastward to China and southward to Malaysia and the Philippines. Their range also extends to tropical Africa, Madagascar, and the islands of the Indian Ocean. The genus name "Acampe" originates from the Greek word "akampas," meaning "rigid," a descriptor alluding to the small, brittle, and inflexible nature of their flowers.
Characteristics
Acampe orchids are characterized by their slow-growing, vine-like habit, often forming substantial vegetative masses in their natural environments. They possess thick, leathery leaves that are distichous, meaning they are arranged in two opposite rows along the stem. The flowers, while small to medium in size, are notable for their fragrance. They are typically yellow, adorned with orange or red stripes. The inflorescence is a racemose type, bearing a few to many flowers. The sepals and petals are similar and brittle. The labellum, or lip, is ear-shaped, fringed, and saccate (sac-shaped) or has a spur, usually featuring red markings at its base. The column of the flower is short and fleshy, bearing two waxy pollinia, which are the pollen masses.
Cultivation and Distribution
Due to their large growth habit and the relatively small size of their flowers, Acampe species are rarely cultivated by orchid enthusiasts. The genus encompasses eight recognized species as of May 2014, with species like Acampe carinata, Acampe ochracea, and Acampe rigida having broad distributions across various Asian countries. Acampe pachyglossa is notable for its distribution in Africa and islands of the Indian Ocean. Acampe also participates in intergeneric hybridization, forming hybrids such as × Aracampe (with Arachnis) and × Vancampe (with Vanda).
