Flores morphologice hermaphroditi, sed abortu physiologice unisexuales, perigoniati. Flores masculi: Perigonium 4-tepalum, tepalis cuneatis vel spathulatis, concavis, apice incrassatis depressis; stamina 4; filamenta brevia, dilatata, subclavata, compressa, antherae connectivum superantes, thecis ovato-ellipticis rima longitudinali introrsum dehiscentibus, pollen in farciminulis emittentibus; ovarium breve, oblongum, stigmate sessili coronatum, perigonio superatum, ovulis in loculis fere tota longitudine placentae adnatis vel abortivis. Flores steriles: Tepala pistillodium claviforme includentia. Flores feminei: Tepala vertice magis incrassata, subfornicata; stamina imperfecta; ovarium ovoideum, in stilum brevem attenuatum, 2-loculare, loculis uniovulatis; ovula subamphitropa funiculo brevi placentae centrali basi affixa. Stigma capitatum. – Herba rhizomate horizontali crassissimo, turiones nonnullas cataphyllis 2–4 et folio unico praeditas proferente. (Vide notam.) Folium magnum ad basin petioli vagina fere a basi libera biauriculata instructum; petiolus teres, basi incrassatus, infra laminam demum nodoso-geniculatus, lamina crassa pinnata, pinnis juvenculis imbricatim sese obtegentibus, demum deciduis atque in tubera excrescentibus (Fig. 85 H). (Conf. Lynch in Gard. Chron. XIV. (1880) 375, Engl. in Engler’s Bot. Jahrb. I. 189.) Pedunculus brevis vix spadicem aequans. Spatha extus viridis, intus albida; tubus inflorescentiam femineam involvens, quam lamina cymbiformis, dorso infra apicem cornuta, horizontaliter patens duplo brevior. Spadix cylindricus medio constrictus, densiflorus, inferne flores femineos, superne flores masculos, media parte constricta flores steriles, omnes contiguos, gerens.
Species solitaria, insulas Sansibar et Bourbon atque Africae orientalis partem inhabitans.
Nota. Turiones post cataphylla 2–3 folium unicum, deinde iterum cataphylla 1–3 et inflorescentiam vel inflorescentias duas ex hac formula proferunt:
Sic in specimine jam 20 annos in horto Berolinensi culto. Attamen in specimine a cl. Hildebrandt ex insula Sansibar introducto vidi post folium cataphylla plura et spatham ex formula:
