Aeranthes grandiflora Lindley 1824 is a member of a genus with 47 species, mostly from shady, tropical humid forests in Zimbabwe, Madagascar and islands in the Western Indian Ocean. The name "aeranthes" means 'aerial flower”, because it grows high in the air.. It has a single short, erect, monopodial stem. The leathery, shining, opposite leaves are arranged in two rows of five to seven leaves, with a length of 15–25 cm. New leaves are formed at the top of the stem in a monopodial growth pattern.

A. grandiflora is the type species of its genus. It is native to Madagascar. It is characterized by long, spindly, naturally hanging inflorescences and relatively large, semi-translucent greenish yellow flowers. which open successively over a long period of time and have an agreeable, sweet scent in the evening or early morning. The threadlike flower stalk, after the first flower has faded, shouldn’t be cutted, because these plants rebloom abundantly. Home culture for this species is among the easiest of any orchid.
