Flores infimis steriHbus exceptis hermaphroditi, nudi. Fertiles: Stamina 4, fila- 

 menta compressula^ latiuscula, apice repentino in connectivum tenue acuminatum an- 

 gustata, pistillum vix superantia, antherae dithecae thecis oblongis apiculatis connectivum 

 superantibus, loculis suboppositis extrorsum versis, rima longitudinali ad basin non ex- 

 tensa lateralibus dehiscentibus. Ovarium obconice prismaticum, biloculare; ovula in lo- 

 culis 2, anatropa, funiculis brevissimis placentae gibbosae in fundo cavitatis lateraliter 

 affixis, micropyle fundum spectante. Stilus ovario aequilongus, crassior, vertice trun- 

 cato medio leviter elevatus; stigma depresso-oblongatum vel lineare (plerumque spadicis 

 directionem sequens). Flores steriles: Staminodia 4 minuta, conoidea. Ovarii rudimen- 

 tum prismaticum 2-loculare; ovula deficientia; stigma magis depressum. Fructus bac- 

 cati, conferti, partem disciformem sponte solutam abjicientes, membrana tenuissima 

 tunc tantum vestiti, persistentes, molliter pulposi, loculis vix distinguendis semina per- 

 pauca (1 — 3) gerentibus. Semen obverse ovatum vel subcordatum, compressulum, fu- 

 niculo vix conspicuo, epidermide solubili, testa crassiuscula. Embryo macropodus; al- 

 bumen nullum. — Frutices scandentes Americae centralis atque australis tropicae, hinc 

 illinc radicantes, plus minusve dense distiche foliosi, foliis sequentibus inter se vagina 

 atque lamina antidromis. Folia stirpis juvenculae saepe pai-va ovata vel ovato-cordata, 

 brevius petiolata, lamina appressa radices obtegente. Foliorum petiolus ad medium 

 usque vel ultra medium vagina vegeto-persistente vel stupose decomposita vel ex toto 

 decidua instructus, lamina varia, integra, plerumque oblonga inaequilateralis, saepe per- 

 forata, rarius pinnatifida. Pedunculi ad apices ramorum solitarii vel plures sympodium 

 rhipidiforme efformantes. Spatha ovata vel oblongo-ovata, apiculata, cymbiformi-convo- 

 luta, post foecundationem reclusa, serius decidua. Spadix haud stipitatus, liber, subcy- 

 lindricus, dense multiflorus, quam spatha plus minusve brevior, floribus infimis sterilibus, 

 reliquis hermaphroditis obsessus.
