Bulbophyllum raulersoniae

A tiny epiphytic Bulbophyllum known only from Guam and Rota in the Mariana Islands, found by Lynn Raulerson in 1986 and described in 2022. It is smaller than B. guamense, has pseudobulbs that persist with a leaf scar after the leaf drops, and bears solitary flowers that last only about two days, several times a year. It grows in the understory of moist forest on elevated limestone.
