Aganisia is a small genus of orchids in the family Orchidaceae (subfamily Epidendroideae), comprising four accepted species native to tropical South America and Trinidad. These are dwarf, epiphytic climbing orchids that grow from a creeping rhizome, producing pseudobulbs and small flowers that generally reach about 4 cm in width. Flower color ranges from rose-tinted violet to blue-tinted violet; structurally, the flowers bear a short column foot and an elongate stipe. The genus is found in mountainous or savanna forests and alongside rivers across a wide range including Trinidad, Brazil, Colombia, Venezuela, Guyana, French Guiana, Suriname, and Peru. Aganisia are rarely encountered in cultivation.
