Agrostophyllum is a genus with about ninety species from the orchid family (Orchidaceae). The genus name is derived from the Greek words agrostis ("grass") and phyllos ("leaf"), referring to the grass-like appearance of the leaves of some species. These epiphytic orchids occur in tropical lowland forests, growing on trunks or branches of trees. They are found from the Seychelles, Madagascar, India, Sri Lanka, Malaysia, Indonesia to the Pacific Islands. The center of diversity is to be found in New Guinea, with at least 45 species.
