    ACACIA Mill.

    VER...Acaciella, Mariosousa, Senegalia y Vachellia

    Una especie adicional, Acacia mangium Willd. (Racosperma mangium (Willd.) Pedley) es cultivada como ornamental y ha sido usada en reforestación cerca de Nueva Guinea (Zelaya). Esta difiere de la especie nativa en las hojas maduras que son filodios (pecíolos expandidos a modo de hojas pero sin láminas verdaderas); los filodios son de hasta 25 cm de largo, 2–4 veces tan largos como anchos y tienen 4 nervios longitudinales fuertes. Esta especie también se caracteriza por sus ramas agudamente triangulares y espigas florales largas.

    Woody plants, usually armed with scattered thorns or stipular spines. Leaves (Central American species) bipinnate, the pinnae few or many, opposite, the leaf- lets mostly small and numerous; petiole in the majority of species bearing some sort of a gland or glandular field; rachis short or elongate, glandular or less often eglandular; stipules usually small and caducous but sometimes modified as promi- nent spines, in the "bull-horn" species these very large and myrmecophilous. In- florescence basically of axillary, solitary or fasciculate, pedunculate heads, spikes, umbels or racemes, often appearing paniculate because of suppression of leaves at terminal and subterminal, floriferous nodes. Flowers small, usually numerous and dense, predominately whitish or yellowish, normally exceeding the bractlets; calyx usually campanulate, sympetalous, 4- or 5-toothed; corolla typically funnelform, sympetalous for most of its length or in some species 4- to 5-cleft nearly to the base; stamens diagnostic, numerous, free or rarely somewhat united at the extreme base; anthers small, rarely glandular; ovary small, the style and terminal stigma scarcely visible among the stamens. Legume usually oblong to linear, terete or more frequently compressed or flattened, usually straight, dehiscent and with slightly elevated margins, the seeds transverse.

    Morphology

    Leaves bipinnate or (in introduced species) often modified to phyllodes (entire, leaf-like often flattened organs, without pinnae or leaflets); pinnae each with one to many pairs of leaflets; gland on upper side of petiole usually present; glands often also present at insertion of pinnae
