Bulbophyllum adolinae is similar to B. octarrhenipetalum J.J.Sm. but differs in the terminal callus of the column-foot, which is bilobed, with one lobe pointing upwards and one, almost equally large, lobe pointing downwards (versus only one upwards-pointing callus in B. octarrhenipetalum); rostellum minute, erect (versus rostellum distinctly protruding, porrect); petals only 0.6 mm wide (versus petals 0.09–0.25 cm wide), sepals with glabrous, not ciliate, margins, and the bright yellow lip (versus lip white or purple).
Bulbophyllum adolinae is named at the occasion of the 2018 International Conference on Biodiversity, Ecotourism, and Creative Economy (ICBE), Manokwari, 2018, in honour of Mrs. Juliana Adolina Kiriwenno Mandacan, chairwoman of the West Papua chapter of the Orchid Association of Indonesia; she is the wife of the governor of West Papua Province, Dominggus Mandacan, who is a powerful driver of nature conservation efforts in West Papua Province
