Inflorescences interfoliar; peduncular bract to 40 cm long, yellowish brown on outer surface, sparsely to moderately covered with yellowish brown spines to 1 cm long; pistillate flowers and fruits with a "staminodial ring" between the calyx and corolla; fruits 3.5-4 × 2-3 cm, ellipsoid or obovoid, rostrate, purple-black, minutely spinulose.

  • Discussion

    The stems are used for making baskets and the fruits are eaten (Balick et al 1428).
