Part shade Warm Cool

Common Name The Bright Colored Bulbophyllum [refers to the flowers]

Flower Size .12" [3 mm] wide

Found in Sarawak Borneo in podzolic forests with a mossy forest floor, at elevations around 1000 meters as a mini-miniature sized, warm to cool growing epiphyte with a creeping rhizome giving rise to distinct, .16 to .28" [.4 to .7 cm] between each, ovoid, not laterally flattened pseudobulb carrying a single, apical, ovate, acute, petiolate base leaf that blooms on an erect to patent, peduncle to 1.2 to 1.52" [3 to 3.8 cm] long, provided with 3 to 8 bracts, rachis erect, somewhat thickened, .04 to .06" [.1 to .15 cm] long, 2 flowered inflorescence with ovate, acuminate, shorter to slightly longer than the ovary floral bracts and carrying flowers with the sepals and petals buttercup-yellow and an orange-red lip.

"The flowers are rather similar to those of B. medusae (Lindl.) Rchb. f., but this species is much larger in all parts, and has a many-flowered inflorescence. The general habit of B. laetum is reminiscent of the SECTION Biflorae Garay, Hamer, & Siegrist 1994 species B. biflorum Teijsm. & Binn., and B. hymenochilum Kraenzl., although these species are all larger, and have larger flowers."
