    Distribution
    Sansibar-Inhambane regional mosaic to south eathern part of the Zambesic region: from Central Tansania to South Mosambic, in the west to Zimbabwe and in the north to South Zaire
    Phenology
    Flowers from October to December.
    Diagnostic
    Basal inner side of the spathe with distinctly raised, parallel running ribs or with platform-like emergences which mimic ribs; open limb of the spathe short to elongate-broadly elliptic (‘oval’) triangular, not twisted along its length axis by 180º; Spadix usually ± as long or somewhat longer than the spathe, basal inner side of the spathe with platform-like and wart-like emergences, these forming ribs which are unevenly high in lateral view and interrupted; Ovary unilocular
    General Description
    Tuber globose, whitish to cream coloured to greenish, roots emerge on the upper surface, 4-8 x 2-4. LEAF 60-70 cm high. Petiole 30-40 cm long. Blade 30-60 cm in diameter, main segments and end leaflets equally frequently divided; rachis broadly winged, broadly elliptic ('oval') to cuneiform ('keilförmig') from the first branching; terminal leaflets broadly elliptic ('oval') to elongate , 7-10 x 2-3 cm, with a distinctly delimited tip, this 1 cm long. Cataphylls 2?, 8-20 x 2-3 cm, outside red brown with whitish spots, inside dark green. INFLORESCENCE distinctly stipitate, emerging before the leaf, up to 60 cm high. Peduncle 12-28 cm long, 0.5-1 cm in diameter. Spathe 15-28 cm long, arranged into a ± cylindrical tube and a broadly elliptic ('oval') to long, triangular open limb. Tube 4-8 x 2-4 cm, ± cylindrical; basally rounded, outside probably green purple to purple, with darker and small spots; inside basally with "ribs" ('"Rippen"'), which are formed of narrow platform-like and irregularly shaped emergences, these appear unevenly high (like mountain chains) from the side, to 1.2 mm high, not running parallel, ribs very congested, red brown, the constriction distinctly set off against the inside as light (1-2 cm wide) ring. Open limb erect, 10-20 cm long, elongate or elongate dreieckig, outside and inside green purple to purple, towards the margin becoming dark purple; margin undulate to frilly lobed. Spadix sessile, 19-28 cm long, ± as long as the spathe. Pistillate zone cylindrical to conical, 2-2.5 x 1-1.6 cm, flowers congested. Staminate zone cylindrical to obconic, 2.5-5 x 1-2 cm, flowers congested. Appendix 13-18 cm long, 1-1.5 cm in diameter at the base, narrowly conical, in the lower third sometimes with very small warts, these loosely and unevenly dispersed; basally slightly constricted, red brown bo purple. Staminodes sometimes as very small, irregular warts in the lower third of the appendix. Sterile zone between the pistillate and staminate zone absent; ratio of pistillate to staminate zone 0.5-0.7 : 1. Pistillate flowers 3-4 mm long; ovary elongate to globose, 2 x 2-3 mm, uni(-bi)locular; stigma sessile, circular form above, broadly elliptic ('oval') to circular from the side, unlobed or rarely with two flat-globose elevations. Staminate flowers: 2-4 stamens forming one flower; anthers free, 1 x 1.5 mm, elongate, rectangular to cylindrical; filament 0.5-2 mm long, free; pores apical, circular to broadly elliptic ('oval') , 1 pore per theca visible; connective channelled, darker coloured than the theca. Pollen inaperturate, 46-36µm, ovoid, exine smooth (psilate). INFRUCTESCENCE unknown. Smell a numbing stench (Garcke 1864).
    Habitat
    Probably not a rare plant of savannas, bush savannas and tree savannas, On sand soils with loam content. Often dispersed in open forest landscapes and tree savannas with Brachystegia, Julbernardia, Terminalia mokllis, Perminalia sericea, Oldfieldia pericopis and Combretum spp. (in sched. Greenway 14761, Condgon 132).
