Part shadeHotWarm LATEFall TO EARLY Winter

Common Name The Tiny Diamond Bulbophyllum [refers to the petals]

Flower Size 1” [2.5 cm]

Found in New Guinea, the Solomon Islands and Vanuatu on trees in forests at elevations around 500 to 1200 meters as a mini-miniature sized, hot to warm growing epiphyte with ovoid to cylindical-ovoid pseudobulbs carrying a single, apical, erect to suberect, ligulate to oblong-ligulate, minutely apiculate, glabrous leaf that blooms in the late fall and early winter on a basal, thin, filiform, 1 to 1.2” [2.5 to 3 cm] long, single flowered inflorescence

Schlechter states that the flowers are red, the lip golden yellow but red at the base. He also says it is similar to B chrysoglossum but B microrhombos differs in the thicker pseudobulb, much shorter leaves, and the small rhombic petals.
