    Appearance: Evergreen, unarmed tree to 15 m (50 ft) tall, with compact spread, often multi-stemmed; young growth glaucous.

    Leaves: Alternate, simple, reduced to flattened blade-like phyllodes slightly curved, 11–20 cm (5–8 in) long, with 3–7 main parallel veins and a marginal gland near the base; surfaces dark green.

    Flowers: Loose, yellow-orange spikes at leaf axils or in clusters of spikes at stem tips; flowers mimosa-like, with numerous free stamens.

    Fruit: Flat, oblong pod, twisted at maturity, splitting to reveal flat black seeds attached by orange, string-like arils.

    Ecological threat: Has invaded pinelands, scrub, and hammocks in south Florida. Displaces native vegetation, and threatens to shade out rare plants. FLEPPC Category I

    Distribution: SW, SE
