Flueggea neowawraea is a tree that can reach up to 30 meters in height and 2 meters in diameter. The bark is pale brown, rough, and scaly, with abundant whitish lenticels. The shoots are glabrous, and the tree features a reddish-brown sapwood and black heartwood. The sap of the tree is watery. The leaves are simple and alternate, with ovate-elliptic blades measuring 4–14 cm in length and 2–9 cm in width. They have an acute apex and a base that can be truncate, rounded, or oblique. The leaves are glabrous, thin, and chartaceous, with green upper surfaces and pale green, glaucous lower surfaces. The margins are entire, and the leaves are pinnately veined with 0.5–2 cm long petioles. Stipules are present, deltate in shape, 2–3 cm long, with laciniate–ciliate margins. It has axillary flower clusters. Staminate flowers have pedicels 3–4 mm long, while pistillate flowers have pedicels 5–14 mm long. It is either dioecious or rarely monoecious, with unisexual, actinomorphic flowers. Staminate flowers have a calyx with five green sepals with brownish tips, and pistillate flowers have five unequal sepals. There are no petals. Staminate flowers have 4–7 stamens, while pistillate flowers have a superior ovary with two ovules per cell and two-lobed stigmas. The fruit is reddish-brown to black, juicy, globose, 3–6 mm in diameter, and subtended by persistent sepals, borne on 5–20 mm long pedicels. The seeds are slightly curved, approximately 3 mm long, and about 1 mm wide, with a deep subhilar invagination on the seed coat and an embryo embedded in endosperm. It inhabits dry to mesic forests at elevations ranging from 250-1,000 meters.
