Found in Papua New Guinea on steep slopes in montane forests at unknown elevations as a miniature sized, warm to cool growing epiphyte with 1.2 to 1.4" [3 to 4 cm] between each ellipsoid pseudobulb carrying a single, apical, ovate, acute, petiolate base leaf that blooms on a porrect, .4 to .48" [1 to 1.2 cm] long peduncle, 3 bracted, .72 to 1.2" [1.8 to 3 cm] long, 6 to 9 flowered inflorescence with an acuminate floral bract and carrying nonresupinate flowers.

According to J J Vermuellen - "Bulbophyllum argoxanthum keys out as B. fractiflexum J. J. Sm. in Vermeulen (1993). It differs, however, in having rounded, glabrous, shorter and wider sepals and petals (dorsal sepal index length/width 2.211.4 in B. fractiflexum) and acute stelidia."
