Taxonomy and naming The pineapple orchid was first formally described in 1868 by Ferdinand von Mueller who gave it the name ''Cirrhopetalum elisae'' and published the description in the ''Fragmenta phytographiae Australiae'' from a specimen collected near Tenterfield. In 1873, George Bentham changed the name to ''Bulbophyllum elisae''. The specific epithet (''elisae'') honours Eliza Kern.
Distribution and habitat ''Bulbophyllum elisae'' grows on the highest branches of rainforest trees, sometimes on cliff faces and boulders. It occurs between the Bunya Mountains in Queensland and the Blue Mountains in New South Wales.
