Leaves bipinnate; stipules usually small, rarely larger and caducous; petiole and rachis with glands; leaflets small in numerous pairs or larger in few pairs. Inflorescences of globose heads, arranged in axillary or terminal panicles. Flowers bisexual. Calyx campanulate or funnel-shaped, 5-toothed. Corolla funnel-shaped, upper part 5-lobed. Stamens numerous, connate into a tube at base, free part of filaments long exserted; anthers small. Central flowers of heads with broader calyx and much longer filament tube. Ovary flattened; style long, slender; stigma minute. Legume broadly linear or oblong, straight, plano-compressed, indehiscent, or dehiscent along both sutures, continuous inside.

    ALBIZIA Durazz.

    Por Lourdes Rico (modifications A. Pool, July 2010)

    Arboles o arbustos, en su mayoría inermes; plantas hermafroditas o poligamodioicas. Hojas bipinnadas. Inflorescencias paniculadas o fasciculadas, flores en capítulos, en algunas especies los capítulos son heteromorfos, la flor central es generalmente más desarrollada que las periféricas; estambres más de 10, monadelfos. La mayoría de las especies neotropicales presentan fruto plano, recto, generalmente cartáceo y no septado, dehiscente o indehiscente; semillas aplanadas y elipsoides, cafés o blanquecinas, sin arilo.

    Género con ca 150 especies ampliamente distribuidas en los trópicos, con la mayor diversidad en Africa; 7 especies se conocen en Nicaragua. Albizia continúa siendo uno de los géneros difíciles de separar de Pithecellobium sensu lato, con el que frecuentemente se confunde, especialmente cuando el material carece de frutos. Uno de los principales problemas es la enorme variación en el fruto de las diferentes especies. Para este tratamiento se ha considerado como carácter distintivo para Albizia el tipo particular de inflorescencia como la presente en A. niopoides. Las inflorescencias de A. saman (Samanea saman) y A. guachapele (Pseudosamanea guachapele) son algo diferentes de las del resto de las especies aquí incluidas. Si bien algunos autores tratan a éstas y otras especies en géneros más pequeños, pienso que se requiere un estudio detallado y al momento trato a Albizia en su sentido circumtropical. [We treat here under the segretate genus names for technical reasons]

    Trees or shrubs, mostly unarmed, pubescent or glabrous. Leaves few-ranked, usually large, bipinnate, the pinnae and leaflets few to many pairs; petiole gland- ular, the gland usually borne near or below the middle, less frequently above the middle, -but always below insertion of the lowermost pair of pinnae; petiolar gland concave, longitudinally oblong and sunken in the petiole to orbicular and erect; rachis and pinnular rachis usually also bearing glands, especially towards the tips; leaflets small and linear to moderate and ovate, variously pubescent; stipules usually caducous or lacking. Inflorescence of usually subterminal, axillary, pedunculate heads, spikes, or umbels. Flowers pentamerous, synsepalous and sympetalous, regu- lar, almost invariably perfect, white to pink; calyx campanulate to tubular, toothed apically, usually pubescent; corolla mostly funnelform, valvate; stamens numerous, united below into a staminal tube which is usually included; anthers small, egland- ular. Legume linear to oblong, relatively broad but very flat and thin, straight, dry, not septate, indehiscent or tardily dehiscent, the valves never contorted nor elastically dehiscent, the seeds transverse.
