Cyanea pseudofauriei is a shrub or small treelet ranging in height from 0.9 to 3.7 meters. Its stems are unbranched or occasionally sparingly branched, measuring 0.7–1.1 cm in diameter at the apex. The stems are glabrous, contain chambered pith, and exude white latex when damaged. The leaves are simple and arranged alternately along the stem. Leaf blades are narrowly elliptic or oblanceolate, measuring 11.5–24.5 cm in length and 2.8–5.5 cm in width. The leaf apex is obtuse or acute, and the base is cuneate. The upper surfaces are light green and glabrous, while the lower surfaces are whitish green with either sparse pubescence along the midrib or nearly glabrous overall. Leaf margins are crenulate. Petioles are glabrous, 2.5–11 cm long and 1.2–2.5 mm in diameter, typically comprising one-fifth to one-half the length of the blade. Stipules are absent. The flowers are bisexual (perfect) and arranged in racemes of 9 to 30 flowers. The peduncle ranges from 20 to 75 mm in length and is glabrous, becoming ascending when short and decurved when long. The rachis is 8–10 mm long and glabrous. Bracts are triangular or deltoid, 0.7–1.4 mm long, pubescent, and deciduous, located just beneath the pedicels. The pedicels are ascending, 9–14 mm long, and glabrous, bearing two small, pubescent bracteoles about one-third to halfway up their length. The hypanthium is broadly ellipsoid or hemispherical, 3–5 mm long and 3–4.7 mm in diameter, and glabrous. Calyx lobes are triangular or deltate, 0.3–0.8 mm long, pubescent, and acuminate at the apex. The corolla is 25–31 mm long, white-tinged, or striped with purple, and glabrous. The tube is suberect and varies in diameter along its length, narrowing at the middle and flaring again at the mouth. Dorsal corolla lobes are linear-triangular, 10–14 mm long, acuminate, and may be about half to slightly longer than the tube. The ventral lobes are slightly shorter, measuring 8–11 mm in length, and are connate at their base. The staminal column is exserted, emerging above or between the dorsal corolla lobes. Stamens are five in number, alternate with the corolla lobes, and connate into a slightly downcurved filament tube 18–21 mm long. Dorsal anthers are 7–8 mm long, while ventral anthers are 5–6.5 mm long and bear tufts of hairs 1.2–2.2 mm long at the apex. All anthers are glabrous and open by longitudinal slits. The ovary is inferior and 2-celled, with axile placentation and a bilobed stigma that remains appressed and nonreceptive while the style grows through the anther tube; the stigma becomes receptive only after pollen dispersal. The fruits are purple, globose berries 6–8 mm in both length and diameter. Seeds are numerous, ellipsoid, orangish-brown, and 0.5–0.7 mm long, with a finely papillose seed coat and a glossy appearance. It is found in mesic forests at elevations ranging from 165- 640 meters.
