Bulbophyllum raulersoniae is a small epiphytic orchid with pseudobulbs and single-flowered blooms, endemic to the limestone forests of Guam and Rota in the Marianas. As a tropical epiphyte it needs humid, bright but filtered conditions and good air movement, with the roots allowed to dry slightly between waterings.
Bulbophyllum raulersoniae is a species of orchid in the section Codonosiphon. It is endemic to the islands of Guam and Rota in the Marianas Archipelago. The species was named posthumously after Dr. Lynn Raulerson, professor of biology at the University of Guam, who had discovered the species in 1986. After going unnamed for 36 years, the species was first described and named in the OrchideenJournal in 2022 by Banjamin Deloso, Charles Paulino, and Jim Cootes.
The species is only known to occur in moist forests of elevated limestone on the islands of Guam and Rota, where it grows as an epiphyte in the understory. The type specimen was found in northern Guam in Machanao, near Potts Junction at about 140 meters above sea level, growing on Morinda citrifolia. Since then, this habitat has been cleared for development, and there were no observations of the species during a 2016/2017 survey at the nearby Anderson Airforce Base in northern Guam.
