Abdominea minimiflora, or the Tiny-flowered Abdominea, is a very rare monopodial epiphytic orchid species and the only species of the monospecific genus Abdominea. It is distributed from Thailand to the Malay peninsula, Java, and the Philippines. The name is derived from the Latin abdomen, meaning belly. It refers to the similarity between the shape of the labellum (lip) and the shape of the abdomen of an insect. The species produces very small flowers, about 0.45 cm wide, on a racemose, many-flowered inflorescence.
