Homoranthus bebo L.M.Copel. (family Myrtaceae) is described as a "Decumbent shrub, 0.05–0.2 m tall, 0.5–2 m wide, producing adventitious roots on prostrate branches, glabrous. Leaves opposite, decussate, punctate, aromatic, 3–7 mm long, 0.2–0.5 mm wide, 0.5–0.8 mm thick, linear, mucronate, shortly petiolate, shiny, lime-green; blade in side view straight to incurved linear; petiole 0.5–0.8 mm long, slightly glaucous. Flowering branchlets undifferentiated, with 3–10 flowers held erect in leaf axils towards branchlet apex. Inflorescence a monad; peduncles 0.7–1.7 mm long; bracteoles caducous, 2.0–3.5 mm long, pale purple. Hypanthium cylindrical, 5-costate, smooth between the ribs, glabrous, 2.0–3.3 mm long, pale yellow–green. Sepals 5, 1.0–2.2 mm long, yellow, the margin entire, the apex long acuminate. Petals 5, yellow, broadly obovate, the apex obtuse, 0.5–1.2 mm long, the margin entire. Stamens 10; filaments ~0.4 mm long; anthers globose, basifixed, yellow-brown. Staminodes 10, alternating with the stamens, distinctly adnate to the adjacent antepetalous stamen. Style 6–9 mm long, exceeding the hypanthium by 3–5 mm at anthesis, minutely hirsute below the papillose stigma, yellow. Ovary unilocular; placenta sessile, axile-basal, bearing 8–10 ovules.
