Inflorescence axillary, a fascicle, the axis ca. 3 mm long, pubescent, the indumentum yellowish; bracts deltate, 0.5 × 0.5 mm, pubescent, caducous after anthesis; pedicels 2–4 mm long, pubescent; bracteoles deltate, 0.5 × 0.5 mm, pubescent, caducous after anthesis; flower buds globose, 5 × 3 mm, not constricted above ovary; calyx-lobes free, four, deltate, 1 × 1.3 mm, pubescent adaxially and glabrous abaxially, not reflexed, persistent in the fruit; ovary not seen. Immature fruit ellipsoid, 1.5–1.9 × 0.8 cm, glabrous, surface with glands marked, no mature fruits examined.

Note:— Eugenia wullschlaegeliana may be recognized by its leaves, which are ovate, elliptic, or broadly elliptic; its inflorescence forming a pubescent fascicle, with yellowish indumentum; and its glabrous, ellipsoid fruit, with marked glands on the surface.
