General Description
Habit: solitary, erect but sometimes decumbent, 0.3-2 m tall. Stem: 2-3 cm diam., green, smooth, conspicuously ringed, internodes 2-5 cm long. Leaves: 4-5, spreading, bifid, 90-125 cm long; sheath 15-25 cm long, obliquely long-open, tubular only in basal 2/3; petiole 15-25 cm long, flattened and green above with lower margins of blade faintly visible as they extend on either side to sheath, rounded and pale below; rachis 20-35 cm long, angled and green above, rounded and pale below; blade 50-70 x 25-35 cm, obovate, incised apically to 1/2 its length, lobes broadly lanceolate, 25-35 x 15-20 cm, cuneate basally, outer margins toothed, 20 primary nerves on each side of rachis. Inflorescences: interfoliar, sometimes infrafoliar in fruit, spicate, erect, pendulous when heavily laden with fruits. Staminate 4-10 per node, middle one developing and opening first; peduncle 20-25 x 0.5-1 cm, rounded, green in flower; bracts 4-5, prophyll 3 cm long, 2nd bract 8 cm, 3rd 15 cm, 4th 15-20 cm, ± loosely sheathing, becoming progressively larger distally, slightly inflated, terminal one equalling or exceeding peduncle, acute-acuminate, bifid, slightly flattened, green when young becoming brownish with age, longitudinally striate-nerved; rachis or flower-bearing portion 10 cm long. Pistillate solitary; peduncle to 30 cm long, 1 cm wide at base, 1.5 cm wide at apex, flattened basally and apically, erect and greenish in flower, downward-curved and orange in fruit; bracts 5, green in flower, similar to those of staminate but fibrous and tattered in fruit; rachis or flower-bearing portion to 15 cm long, ± flattened, I cm wide, 5 mm diam., green and erect in flower, nodding, swollen to 2 cm diam., and orange in fruit. Flowers: Staminate in 6-10 dense spirals, contiguous, 1.5-2 x 2.5-3 mm, depressed-globose, 6-angled by mutual pressure, green, emitting a distinct spicy-anise odor at anthesis, sunken; calyx well developed but not always prominent, often hidden by close packing of flowers, 1-1.5 x 3 mm, lobed, membranous, sepals connate basally, rounded apically; petals varying in width from 1-2 mm, usually 2 wider and 1 narrower per flower, valvate and sometimes slightly imbricate apically, erect for 1.5 mm then abruptly inflexed and tapering to flat pointed tips, tips of adjacent petals closely appressed in bud, opening as slits through which anthers are exserted at anthesis, thick, fleshy; stamens with filaments 1 x 0.75 mm, flattened, fleshy, tapering abruptly apically, anthers 0.75 x 0.3 mm, exserted from between petal slits on distal flat top offlower; pistillode 1.5 mm high, columnar, fleshy, distinctly 3-lobed, rounded tip exposed in center of flower at anthesis. Pistillate in 10-12 dense rows of up to 30 flowers per row, contiguous, 3 x 3 mm, depressed-globose, angled by close packing as those of staminate, greenish changing to greenish yellow, slightly sunken; calyx 1 x 2.5-3 mm, shallowly lobed, sepals connate nearly to apex, broadly rounded apically; petals 2 x 2.5 mm, subreniform, imbricate, tips inflexed to I mm, rounded to straight apically; pistil 3 x 2.5 mm, ovoid, ± 3-sided, greenish, styles short or lacking, stigma 1 mm long, exserted well beyond petals, open, erect, only very slightly if at all reflexed, pale to light yellow. Fruits: 1-1.5 x 0.5-1 cm, ± obovoid-globose and stalked in appearance, contiguous, densely packed, flattened and/or angled by mutual pressure, green when immature becoming red-orange when soft-ripe, finally ageing blackish, epicarp smooth, mesocarp fleshy, endocarp thin; seeds 10 x 7 mm, ovoid; perianth persistent, sepals 1 mm long, petals 2 mm long.
