The Pseudobulbs are densely crowded, ovoid to conical, 10 to 20 mm long by 8 to 15 mm wide, wrinkled and narrowed to a short, slender apex, when young it is covered with white lanose bracts. The leaves are solitary, terminal, oblong-lanceolate to elliptic-lanceolate, 15 to 30 mm long by 5 to 10 mm wide, slightly twisted at the base, thin-textured but tough, dark green on the upper surface with a shallowly sunken mid-vein, paler below, with a shallowly ridged midvein, apex acute to apiculate. The flowers are solitary, thick, fleshy, waxy, white cream or greenish with mauve, dark red or reddish-purple striae. The labellum is greenish to reddish purple. Dorsal sepal 8 to 11 mm long by 3 to 5mm wide with 5 veins prominent. The lateral sepals are 9 to 11 mm long by 9 to 11 mm wide at the base. The petals are 6 to 8 mm long by 2 to 3 mm wide.

Bulbophyllum weinthalii comprises two subspecies, B. weinthalii subsp. weinthalii from the Border Ranges and south to Dorrigo, NSW and B. weinthalii subsp. striatum from Dawes Range and Kroombit Tops, Queensland. Bulbophyllum weinthalii subsp. striatum differs from Bulbophyllum weinthalii subsp. weinthalii in its slightly larger flowers, broader perianth segments and many of the perianth markings being in the form of striae (versus dots or blotches) (Jones, 2001). Spilorchis weinthalii is a synonym.
