Spathae tubus convolutus, herbaceus, persistens, faux constricta ; lamina oblonga vel lanceolata, 
mox recumbens et marcescens, (flava). 
Spadix androgynus, erectus, spatha plerumque multo brevior; spica feminea cylindrica, 
. multiflora, densa, stipitata vel substipitata, interdum organis neutris mixta; mascula 
a feminea ob partem neutram interjectam attenuatam, remota, leviter incrassata, 
cylindroidea, plurifora; appendix subulata, longa vel brevis (in cultis quandoque nulla 
vel obsoleta) leviter et irregulariter sulcato-rugulosa; rhachis spicarum omnium cylindrica.

aperientes et tunc quasi e verticis poris pollen emittentes; pollen in farciminulis exsertum; 
f eminei: ovaria unilocularia (summo apice trilocularia) organis neutris saepe permixta 
alternis, stylus in adolescentibus brevissimus, in adultis nullus; stigmata depressa, 3— 4- 
emarginata, brevissime 3—4-suleata, ovariis multo angustiora, distantia; placentae 
2—3-—4,in variis ovariis, parietales, lineares, pluriovulatae ; funiculi longuli, horizontaliter 
protensi ; ovula funiculo sublateraliter affixa, superposita, biserialia, hemi- vel suborthotropa, 
micropyle versus axim idealem loculamenti spectans; neutri sub synandriis, depresse- 
obpyramidati, vertice truncati, leviter a latere compressuli, inter ovaria oblonga, ovaria 
excedentia, stigmatose-coronafa, albida. 
Fructus. Baccae truncato-obconoideae, densae, virentes rubentesque? in spicam cylindricam 
congestae, spathae tubo tandem disrupente obvallatae, stigmatis rudimento coronatae, 
uniloculares, 2—3-—-4-placentiferae, placentis parietalibus, polyspermis. 
Sem en vel semina turbinato-oblongula, longule-funiculata, strophiolo cum funiculo quasi confluente, 
epidermide diaphana, tenui, horizontaliter protensa; testa crassula, acietato-sulcata,
