Description:
Species Description - Dwarf, single-stemmed plants of understory, the stem very short, unarmed, 5-30 cm X 5-8 mm, the internodes 1- 2 cm long. Leaves 4-8, erect; sheath fibrous, brown arachnoid- tomentose, 5-12 cm long; petiole 15-45 cm long, both sheath and petiole unarmed or sparsely armed with slender, black spines 0.5-2.5 cm long; rachis 5-20 cm long, unarmed; blade entire, deeply bifid and 20-35 cm wide or pinnate with 2(3) pinnae per side, or entire on one side and pinnate on other; pinnae, when present, broadly sigmoid, long-acuminate, 15—30 X 4-7 cm, the apical segments much wider (8— 10 cm). Inflorescences 1-3, interfoliar, erect; peduncle 5-8 cm long; prophyll 4-6 cm long, glabrous, membranous; peduncular bract 6-12 cm long, erect, fusiform, glabrous; spadix simple, short, 1-2 cm long. Fruits few, ovoid, glabrous, purplish black, 12-20 X 10-15 mm, arranged in a globose head.
Distribution and Ecology - Fl (Jan), fr (Mar-Sep); common everywhere on welldrained slopes
