Hoya griffithii is epiphytic and has climbing shoots up to 1.5 m in length and about 4 mm in diameter. The stalked, relatively thin leaves are lanceolate to oblong-lanceolate and 11 to 14 cm long and 2.5 to 4.5 cm wide. The base is wedge-shaped, the apex pointed. They sit on 1 to 3 cm long, robust stems. The leaves are dark green with occasional whitish spots; only the middle vein of the leaf veins is clearly visible. The inflorescence is umbel-shaped and spherical with a 5 to 7 cm long stem. It has about 5 to 10 individual flowers. The sepals are oblong-ovate and measure 7 to 8 × 4.5 mm. The corolla has a diameter of approx. 3 cm and sits on a 4 to 4.5 cm long flower stalk. The flower is white, slightly yellowish to pale pink. On the outside it has single red speckles or is pink in the middle. The crown lobes are broadly ovate, curved sickle-shaped and spread out widely. The edges and tip are slightly bent back. The outside is smooth, the inside with a weak fluff. The corolla lobes are approx. 5 mm long and concave. The outer extension is rounded, the inner extension is drawn out like a tooth. The follicles are spindle-shaped and measure approx. 15 cm in length and 1 cm in diameter. The flower produces little nectar and has an intense fragrance.
