Description:
Genus Description - Small to medium-sized, multi-stemmed, generally armed, monoecious plants of understory; the trunks slender, sometimes very short, rarely solitary and inconspicuous. Leaves usually spiny on sheath and petiole; blade pinnate, sometimes entire and bifid in the smallest species, the margins with minute bristles or setae; when pinnate, leaflets disposed at irregular intervals forming clusters along rachis (except in B. rhaphidacantha). Inflorescences 1 or 2(4) per plant, interfoliar or infrafoliar, 1-branched or simple, the peduncular bract spiny or setose, rarely glabrous; pistillate flowers in triads scattered among paired or solitary staminate flowers, borne either throughout rachilla or restricted to base and then only staminate flowers borne distally. Fruits small, usually globose, orange to red and setose or glabrous, or black and smooth at maturity, 1-seeded.
