Bartholina burmanniana, the spider orchid, is a species of deciduous, geophytic, flowering plant in the family Orchidaceae. It is one of two species within the Bartholina genus, the other being B. etheliae. The species’ common name refers to its spreading and deeply cut lip that is said to resemble a spider's legs. It is native to the Eastern and the Western Cape Provinces of South Africa, flowering from the end of August to the middle of October and peaking in September. This is one of the species sometimes referred to as "spider orchid".
Bartholina burmanniana is rarely found in colonies, growing in small groups or singly in a variety of habitats and soil types. Mass flowering is observed after summer bush fires remove thick vegetation, creating an opportune environment for attracting pollinators. Work undertaken in 2009 has proposed the long-proboscid tabanid fly, Philoliche rostrate, to be the pollinator of this species.
