Staminate with 4-8 rachillae, these 8-15 cm long, 1.5-2 mm diam., green. Pistillate with 4-8 rachillae, these 6 cm long, ± stiff, erect, paral1el or slightly spreading, green in flower, orange in fruit. Flowers: Staminate in fairly dense spirals, 3.5 x 3 mm, obovoid-subglobose, greenish tinged with yellow, slightly sunken; calyx 1.5 x 2 mm, ± shallowly lobed, green, sepals connate in basal 2/3, broadly acute apically; petals 3 x 3 mm, ovate, valvate, connate in basal 2/3, adnate to stamen filaments and pistillode in a short stipe, free but incurved apically at anthesis and later opening more, acute, fleshy; stamens 1-1.5 mm long, appressed around pistillode, filaments very short, anthers 2-cleft apically; pistillode 3 x 2 mm, broadly columnar or ± swollen at middle, yellowish, terminating in a short nipplelike, 3-angled, greenish yellow apex. Pistillate in ± loose spirals, 3 x 2-2.5 mm, ovoid or depressedglobose, greenish yellow, slightly sunken; calyx 1-1.5 x 2.5 mm, deeply lobed, green, brown-margined, sepals connate in basal 1/3-1/2, broadly rounded apically; petals 3 x 2-2.5 mm, ovate, imbricate to 1/2-2/3 to apex, free, erect or slightly recurved, acute apically, slightly thickened and ± fleshy; staminodes toothlike; pistil 2 x 2-2.5 mm, depressed-globose, green, styles short or lacking, stigma lobes short, recurved, thick, pale.
