INFLORESCENCE: l(-2) per leaf, innermost inflorescence (when in pairs) subtended by prophyll; peduncle 4-12 cm long, c. 1.5 cm diam. at apex; spathe 14-23 cm long, (2.5-)3 - 4.5 cm diam. at middle, decurrent for 2-3 cm, outer surface glossy green to whitish-yellow, red-maculate, reddish towards apex, inner surface ivory white; spadix 13-17(-21) cm long overall, fertile male zone 3.5-6.5 cm long, (1.1-)1.5-2.7 cm diam., subcylindric to ellipsoid, acute, sterile male zone 6-8.5 cm long, 1.5-3.3 cm diam., subcylindric, tapering slightly towards apex, female zone 4-5 cm long, 1.7-2.5 cm diam., tapering towards apex. FLOWERS: stamens 3.5-4.8 mm long, 0.6-1 mm diam. at apex; staminodes c. 7 per flower, 3.3-6 mm long, 0.8-1.5 mm diam. at apex, shorter in apical portion of sterile zone, clavate, truncate at apex, prismatic in section, tapering gradually to base; gynoecium 5.5-14.5 mm long, ovary ± cylindric, 3-8.5 mm long, 3-5 mm diam., raphides frequent to common in axis, locules 17-22 per ovary, ovules 2(-3) per locule, chalaza prominent, hemispheric, darker coloured, raphe produced as an appendage overtopping micropyle, integuments containing raphides, ovules well-spaced from one another and inserted on basal half to two thirds of ovary axis, style body much narrower than ovary and greatly elongated, 2.5-7 mm long including crown, becoming toughened and tanniniferous in lower region, softer and lacking tannin apically, scattered raphide cells present, compitum shallow, not penetrating ovary, as deep as style lobes, style crown 2.5-4 mm diam., distinctly lobed, non-tanniniferous, with conspicuous layer of druse cells immediately bordering stigmatic epidermis, central dome present, lobed, broad, equalling or overtopping style lobes, usually somewhat excavated centrally, stylar canals very long, probably entering locules just above insertion of uppermost ovule in each locule, stigma not seen in well-preserved state. INFRUCTESCENCE: submature berry 1.2-1.4 cm long, 0.7-1.1 cm diam., whitish-yellow, suffused and spotted with dark salmon red, bright red when mature with pineapple odour, style persistent, dark brown; seed 2.4-3 mm long, 1-1.2 mm diam., cylindric-ellipsoid.
